3. Press A to exit home position correction and return to regular timekeeping.
   Note
   After performing home position adjustment, enter the Timekeeping Mode and check to make sure that the analog hands and the upper display indicate the same time. If they do not, perform home position adjustment again.

Using the Digital Compass

You can use the Digital Compass Mode to determine the direction of north, and to check your bearing to a destination.

• For information about what you can do to improve digital compass reading accuracy, see "Calibrating the Bearing Sensor" and "Digital Compass Precautions".

To perform a digital compass operation

1. Place the watch on a fl at surface. If you are wearing the watch, make sure that your wrist is horizontal (in relation to the horizon).
2. Point the 12 o'clock position of the watch in the direction you want to check.
3. In any mode (except a setting mode), press C to perform a digital compass operation.

• This will cause the mode dial hand to move to COMP.
• COMP will appear in the lower display to indicate that a digital compass operation is in progress.
• After about two seconds, the second hand will point in the direction of magnetic north, and the display will show the direction or the bearing angle that 12 o'clock is pointed.

• See "Digital Compass Readings" for information about how direction readings are indicated by the watch.

Note

• If there is an angle value in the lower display, it means that the bearing memory record is displayed. If this happens, press E to exit the bearing memory record.

4. To return to the mode you were in immediately before entering the Digital Compass Mode, press D. To enter the Timekeeping Mode, hold down D for at least two seconds.

Digital Compass Readings

• When you press C to start a digital compass operation, COMP will initially appear on the lower display. About two seconds after you start a digital compass operation, an indicator will appear in the lower display to indicate what direction the 12 o'clock position of the watch is pointed. The second hand will point to magnetic north.
• After the fi rst reading is obtained, the watch will continue to take digital compass readings automatically each second for up to 20 seconds. After that, the digital compass operation will stop automatically.
• The direction indicator and angle value will show - - - to indicate that the digital compass operation is complete.
• Auto light is disabled during the 20 seconds that digital compass readings are being taken.
• The following table shows the meanings of each of the direction abbreviations that appear on the lower display.

Direction	Meaning	Direction	Meaning	Direction	Meaning	Direction	Meaning
N	North	NNE	North-northeast	NE	Northeast	ENE	East-northeast
E	East	ESE	East-southeast	SE	Southeast	SSE	South-southeast
S	South	SSW	South-southwest	SW	Southwest	WSW	West-southwest
W	West	WNW	Westnorthwest	NW	Northwest	NNW	Northnorthwest

• The margin of error for the angle value and the direction indicator is ±15 degrees while the watch is horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 300 to 330 degrees.
• Note that performing a digital compass operation while the watch is not horizontal (in relation to the horizon) can result in large error.
• You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
• Any ongoing digital compass operation is paused temporarily while the watch is performing an alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by pressing B). The digital compass operation resumes for its remaining duration after the operation that caused it to pause is fi nished.
• See "Digital Compass Precautions"for important information about taking direction readings.
• The direction indicated by the Digital Compass is magnetic north.
  You can use Magnetic Declination Correction to configure the watch to indicate true north, if you want. For details, see "Magnetic Declination Correction" below, "To perform magnetic declination correction", and "Magnetic North and True North".

Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. You can use any one of two different bearing sensor calibration methods: bidirectional calibration or magnetic declination correction.

• Bidirectional Calibration
  Bidirectional calibration calibrates the bearing sensor in relation to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed to magnetic force. This type of calibration should be used if the watch becomes magnetized for any reason.

• To ensure correct direction readings by the digital compass, be sure to perform bidirectional calibration before using it. The digital compass may produce incorrect direction readings if you do not perform bidirectional calibration.
• Magnetic Declination Correction
  With magnetic declination correction, you select a declination angle direction and input a magnetic declination angle (difference between magnetic north and true north), which allows the watch to indicate true north. You can perform this procedure when the magnetic declination angle is indicated on the map you are using.

Precautions about bidirectional calibration

• You can use any two opposing directions for bidirectional calibration. You must, however, make sure that they are 180 degrees opposite each other. Remember that if you perform the procedure incorrectly, you will get wrong bearing sensor readings.
• Do not move the watch while calibration of either direction is in progress.
• You should perform bidirectional calibration in an environment that is the same as that where you plan to be taking direction readings. If you plan to take direction readings in an open fi eld, for example, calibrate in an open field.

To perform bidirectional calibration

1. In the Digital Compass Mode, hold down A.

• The second hand will move to 12 o'clock, indicating the bidirectional calibration mode.
• At this time the lower display will show an upward pointing arrow () and the upper display will show -1-. These indicate that the watch is ready for calibration of the fi rst direction.

2. Place the watch on a level surface facing any direction you want, and press C.

• This will start calibration of the fi rst direction.
• -- is shown on the upper display while calibration is being performed.
• When calibration of the fi rst direction is successful, OK appears on the lower display. After that, the arrow changes to downward pointing () and the upper display will show 2, indicating that the watch is ready for calibration of the second direction.

3. Rotate the watch 180 degrees.
4. Press C again.

• This will start calibration of the second direction.
• -- is shown on the upper display while calibration is being performed.
• After calibration is successful, OK appears on the lower display and then the watch will start a digital compass operation.
• ERR will appear on the lower display for a short while if an error occurs. After that, the screen will automatically return to the fi rst direction calibration screen (the one that appears after A is held down in step 1).

To perform magnetic declination correction

1. In the Digital Compass Mode, hold down A.

• The second hand will move to 12 o'clock, indicating the bidirectional calibration mode.

2. Press D.

• The watch will enter the magnetic declination correction mode.
• The lower display will show the current magnetic declination direction, and the upper display will show the current magnetic declination angle value.

3. Use B and E to change the magnetic declination direction and angle setting as required.

North Setting	Setting
Magnetic North	0° (OFF)
True North	E 90° to W 90° E: East declination (Magnetic north is east of true north.) W: West declination (Magnetic north is west of true north.)

• Note that you can input the declination angle in whole degree units only, so you may need to round off the value specifi ed on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.
• You can turn off (0° (OFF)) magnetic declination correction by pressing B and E at the same time.
• The illustration (page E-26) shows the value you should input and the direction setting you should select when the map shows a magnetic declination of 7° West.

4. When the setting is the way you want, press A to exit the setting screen.

Using Bearing Memory
You can save the bearing to a particular destination in bearing memory and use it to ensure you are headed in the correct direction.

To store a direction angle reading in Bearing Memory

1. Point the 12 o'clock position of the watch in the direction of your reference bearing.
2. Press C to start a digital compass operation.

• If a bearing memory direction angle value is already displayed in the upper display, it means that there is a reading already stored in Bearing Memory. If this happens, press E to clear the Bearing Memory reading and exit the bearing memory screen before performing the above step.

3. During the 20 seconds that digital compass readings are being taken, press E to store the current reading in Bearing Memory.

• The Bearing Memory direction angle flashes for about one second in the upper display as it is stored in Bearing Memory. After that, the angle value will stop flashing (indicating that it is Bearing Memory data), and a new 20-second direction reading operation will start.
• You can press C at any time while the Bearing Memory angle value is displayed, to start a new 20-second direction reading operation. Doing so will display the direction angle for the direction that the 12 o'clock position of the watch is pointed. The direction angle of the current reading will disappear from the display after the 20-second direction reading operation is complete.

• The direction stored in Bearing Memory is indicated by Digital Meter in the following cases only.
  • During the first 20 seconds after you display Memory data
  • During a direction reading operation triggered by pressing C while Bearing Memory data is displayed in the lower display
• Pressing E while the Bearing Memory data is displayed will clear the reading currently in Bearing Memory and start a new 20-second direction reading operation.

Bearing Memory Pointer
Digital Meter indicates the bearing stored for a Bearing Memory record.

Bearing straight ahead

Bearing display area (Indicates a bearing within ±60° of 0.)

Bearing outside of display area (Bearing more than 60° left of 0.)

Bearing outside of display area (Bearing more than 60° right of 0.)

Bearing straight back

• To position yourself to move in the direction of the recorded bearing, move around until the Bearing Memory Pointer points straight ahead of you, as shown above.

Example: Advancing to an objective while monitoring your bearing
Even if you lose sight of your objective, you can use a map to store the required bearing in bearing memory and refer to the memorized information to advance to your objective.

1. Set the map.

• For information about how to set a map, see "Positioning a map in accordance with actual surroundings (setting a map)" below.

2. Place the watch on the map at your current location, and point 12 o'clock at your desired objective on the map.
3. Press E to store the direction to your objective in bearing memory. Now you can advance towards your objective while observing the stored direction on the watch display.

• As you progress, the direction to your bearing will change, so you need to keep updating the information in bearing memory.

Positioning a map in accordance with actual surroundings (setting a map)
You can align a map with the northerly direction indicated by the watch, and then compare what is shown on the map with your actual surroundings. This is helpful for checking your current location and the location of your objective. This process is called "setting a map".

• When setting a map, be sure to align the watch with true north. See "Magnetic North and True North" and "Magnetic Declination Correction".

Digital Compass Precautions Magnetic North and True North

The northerly direction can be expressed either as magnetic north or true north, which are different from each other. Also, it is important to keep in mind that magnetic north moves over time.

• Magnetic north is the north that is indicated by the needle of a compass.
• True north, which is the location of the North Pole of the Earth's axis, is the north that is normally indicated on maps.
• The difference between magnetic north and true north is called the Earth"declination". The closer you get to the North Pole, the greater the declination angle.

Location

• Taking a direction reading when you are near a source of strong magnetism can cause large errors in readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.)
• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures picks up magnetism from appliances, etc.
• Accurate direction readings are impossible while in a train, boat, air plane, etc.

Storage

• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of this, you should store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), and household appliances (TVs, personal computers, washing machines, freezers, etc.)
• Whenever you suspect that the watch may have become magnetized, perform the procedure under "To perform bidirectional calibration".

Taking Temperature Readings

This watch uses a temperature sensor to measure temperature.

To take temperature readings

1. While in the Timekeeping Mode, press E to enter the Thermometer Mode.

• The watch will continue to take temperature readings every fi ve seconds for one or two minutes.

2. Press E to return to the Timekeeping Mode.

• The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about one or two minutes after entering the Thermometer Mode.

Temperature

• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to - - - °C (or °F) if a measured temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear as soon as the measured temperature is within the allowable range.

Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See "To specify the temperature unit".

Temperature Sensor Calibration
The temperature sensor built into the watch is calibrated at the factory and normally require no further adjustment. If you notice serious errors in the temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

• Incorrectly calibrating the temperature sensor can result in incorrect readings. Carefully read the following before doing anything.
  • Compare the readings produced by the watch with those of another reliable and accurate thermometer.
  • If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the temperature of the watch time to stabilize.

To calibrate the temperature sensor

1. Take a reading with another measurement device to determine the exact current temperature.
2. With the watch in the Timekeeping Mode, press E to enter the Thermometer Mode.
3. Hold down A for about two seconds until the temperature reading disappears from the upper display. Release A at this time, which will cause the temperature reading to flash, which indicates the setting mode.

4. Use E (+) and B (–) to calibrate the temperature value with the reading of another instrument.

• Each press of a button changes the temperature value in units of 0.1°C (0.2°F).
• To return the currently flashing value to its initial factory default setting, press E and B at the same time.

5. Press A to complete calibration and restart the temperature reading operation.

Thermometer Precautions
Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.

• Always make sure you are in a safe place whenever you are reading the display of the watch using auto light. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by auto light does not startle or distract others around you.
• When you are wearing the watch, make sure that auto light is disabled before riding on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of auto light can create a distraction, which can result in a traffi c accident and serious personal injury.

Note

• Auto light is always disabled, regardless of its enabled/disabled setting, when any one of the following conditions exists. While an alarm is sounding While the watch is in the Digital Compass Mode

To enable or disable auto light
In the Timekeeping Mode, hold down B for about three seconds to toggle auto light between enabled (LT shown on the lower display) and disabled (LT not displayed).

• The auto light enabled indicator (LT) is on the lower display in all modes while auto light is enabled.
• Auto light remains enabled for about six hours. After that it becomes disabled automatically.

Illumination Precautions

• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.

Auto light precautions

• Illumination may not turn on if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground.
• Illumination turns off after the preset illumination duration, even if you keep the watch pointed towards your face.
• Static electricity or magnetic force can interfere with proper operation of auto light. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.
• You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of auto light, and does not indicate a problem with the watch.

Button Operation Tone

When enabled, the button operation tone sounds any time you press one of the watch's buttons. You can enable or disable the button operation tone as desired.

• Even if you disable the button operation tone, the alarm, Hourly Time Signal, and Countdown Timer Mode alarm all operate normally.

To enable or disable the button operation tone

1. In the Timekeeping Mode, hold down A until ADJ appears in the lower display.

• When you release A (after ADJ appears), SET will be flashing in the upper display.

2. Use D to cycle through settings on the lower display until the current button operation tone setting (MUTE or KEY ) is shown.

• See the sequence in step 2 of the procedure under "To change the current time and date settings" for information about how to scroll through setting screens.

3. Press E to toggle the button operation tone setting between enabled (KEY ) and disabled (MUTE).
4. After the setting is the way you want, press A to exit the setting screen.
   Note

• The mute indicator is displayed in all modes when the button operation tone is disabled.

Low Battery Indication

A low battery indicator appears on the display when the power of the batteries is low. Have the batteries replaced as soon as possible.

Note

• For guidelines covering the life of the batteries and supported battery types, see "Specifications".

The conditions below are in effect while the low battery indicator is flashing.

• All hands are stopped.
• Except for the low battery indicator, all other display functions are disabled.
• Watch tones are disabled.
• Display illumination is disabled.
• Watch operations are disabled.

Note

• Sequentially or repeatedly performing sensor, light, alarm, and other power intensive operations over a short period can cause a sudden drop in battery power, which will make the low battery indicator flash. Even though the low battery indicator may disappear and watch functions may become re-enabled, battery replacement is recommended.

Troubleshooting

Time Setting

• The current time setting is off by a couple of hours.
  Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary.
• The current time setting is off by one hour.
  You may need to change your Home City's standard time/daylight saving time (DST) setting. Use the procedure under "To change the current time and date settings".

World Time Mode

• The time for my World Time City is off in the World Time Mode.
  This could be due to incorrect switching between standard time and daylight saving time. See "To configure World Time City and summer time settings" for more information.

Batteries

• The low battery indicator is flashing on the digital display.
  The watch's battery power is low. Have the batteries replaced as soon as possible. See "Low Battery Indication".
  

Direction and Temperature Readings

• The temperature unit setting won't change.
  The temperature unit setting is always Celsius (°C) whenever TOKYO is selected as the Home City. In this case, the setting cannot be changed.
• "ERR" appears while a sensor operation is in progress.
  Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal circuitry. When this happens, ERR (error) will appear on the display and sensor operations will be disabled.
  

  • If ERR appears while a measurement operation is being performed in a sensor mode, restart the measurement. If ERR appears on the display again, it can mean there is something wrong with the sensor.

  • If ERR keeps appearing during measurement, it could mean there is a problem with the applicable sensor.

"ERR" appears on the display following bidirectional calibration.
If - - appears and then changes to ERR (error) on the calibration screen, it means that there is something wrong with the sensor.

• If ERR disappears after about one second, try performing the calibration again.

• If ERR keeps appearing, contact your original dealer or nearest authorized CASIO distributor to have the watch checked.

Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized CASIO distributor as soon as possible.

Incorrect direction readings.

• Incorrect bidirectional calibration. Perform bidirectional calibration.
• Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move away from large metal objects and try again.

Different results produced by direction readings taken at the same location.
Magnetism generated by nearby high-tension wires is interfering with detection of terrestrial magnetism.
Move away from the high-tension wires and try again.

Problems taking direction readings indoors.
A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism readings. Move away from the object causing the interference or take the direction reading outdoors. Indoor direction readings are particularly diffi cult inside ferro-concrete structures. Remember that you will not be able to take direction readings inside of trains, airplanes, etc.

City Code Table

* As of July 2015, the offi cial UTC offset for Santiago, Chile(SCL) has been changed from -4 to -3, but this watch still uses an offset of +3 (the old offset) for SCL. Because of this, you should leave the summer time setting turned on (which advances the time by one hour) for the SCL time.

• This table shows the city codes of this watch.
• The rules governing global times (GMT differential and UTC offset) and summer time are determined by each individual country.
