   * Packing inside of the lid is used to ensure splash-resistance for the battery compartment. Therefore, make sure to close the battery compartment lid securely.
   
2. Close the lid.
   

* Measured by JEITA (Japan Electronics and Information Technology Industries Association) standards.
The actual battery life may vary depending on circumstances of use.

Replace the batteries
When the batteries become weak, the sound may become weak or distorted, and "E" will flash in the display. After that, when the batteries are used up, "" will light up and clock time display appears. And then the cycle-computer function will be stopped so that any button functions will not work. The Radio function will be also turned off if it is on. If this happens, replace the batteries with new ones. After the batteries are replaced, press RADIO POWER, RESET, or install the unit on the Mount. ("" turn off in the display.)
Note on replacing the batteries
Do not take more than 5 minutes to replace the batteries, otherwise, the clock setting will be initialized. Should that happen, reset the functions.

Notes on batteries

• Do not charge the dry batteries.
• Do not carry the dry batteries together with coins or other metallic objects. It can generate heat if the positive and negative terminals of the batteries accidentally come into contact with metallic objects.
• When you are not going to use the unit for a long time, remove the batteries to avoid damage from battery leakage and corrosion.
• Do not use different types of batteries at the same time.
• When you replace the batteries, replace all with new ones.

Installing the unit on the bicycle

Install the Wheel Magnet

1. Remove the screw of the wheel magnet and open.
2. Attach the magnet between two spokes of the front wheel with the head of the screw facing inward, and tighten the screw.

Install the Mount

1. Choose the appropriate rubber pads according to the diameter of the handlebar and attach them. Use one or two rubber pads depending on the diameter of the handlebar. You can attach the Mount clamps without the rubber pads if not required.
   
   The Mount clamps are adjustable. You can adjust the width of the clamps to fit your handlebar.
2. Install the Mount on the rubber pads and secure with the 4 screws.
   
   
3. Wind the sensor cord around the break cable.
   
   Note
   Be sure to allow enough cord slack to ensure full movement and unhindered operation of the handlebar, and not to wind it too loosely as this may interfere with the unit's operation.
4. Temporarily attach the Sensor to a fork using the attached Double-sided tape.
   
   • When attaching, align the center of the sensor and that of the magnet (triangle mark).
   • Ensure a clearance not exceeding 4mm (except Sensor and Magnet touching) between the Sensor and the Wheel magnet (when aligned).
   • Attach the unit on the Mount, and then check the reaction of the sensor by revolving the wheel (See fig. "Install the unit").
5. After determining the position of the Sensor, secure it with the zip tie to front fork and cut any surplus. Install the Sensor cord with zip ties such that it does not become tangled with the wheel.
   Note
   Be careful that the position of the Sensor does not shift when tightening the zip tie.

Install the unit
Install the unit on the Mount, sliding from the front until it clicks into position.

Remove the unit
Pull the unit forward while pushing down the lever.

Note
Ensure that the contact points between the Mount and the unit are clean for proper operation.

For safe and proper use of the cycle-computer, check whether the Mount, the sensor and its cord and the wheel magnet are set properly before riding.

* There is a tactile dot beside VOL to show the direction to turn up the volume.

For the initial setting (with the radio off)

The cycle-computer needs initial set up before using. If the wheel size you set into the cycle-computer is not suitable for using actual wheel size, it is not possible to measure speed and distance correctly.

1. Press and hold BAND/SET for a few seconds to select "mile" or "km".
   "mile" flashes in the display.
   
   Each press of the ENTER/SELECT toggles between "mile" and "km".
   The unit of speed is "MPH" for miles, and "km/h" for kilometers.
   Select and show the desirred unit.
2. Press BAND/SET to set a wheel size.
   The wheel size flashes.
   
   Press ENTER/SELECT repeatedly to select your wheel size (inches). Each press changes the display as follows.
   
   Note
   The "mm" values shown on the display are approximate. Adjust the accurate size of the wheel using Jog lever + or - after measuring diameter of your wheel.
   It is recommend to set the wheel size in "mm" because the cycle-computer calculates in "mm". If you set the wheel size in "mm", the range is from 300 to 750 mm.
   Push and hold Jog lever to change the value rapidly.
3. Press BAND/SET.
   "ODO" appears in the display, and the last digit of the total distance (odometer) flashes.
   If you do not change the odometer, jump to step 4.
   To change the total distance
   You can change the default setting of the total distance (odometer) using Jog lever + or - (to increase or decrease) and ENTER/SELECT (to select another digit).
4. Press BAND/SET again.
   The initial setting is completed.

Tips

• When you choose the "mile", the range is from 0.0 to 99 999.9 miles.
• When you choose the "km", the range is from 0.0 to 159 999.9 kilometers. And the maximum digit range is from 0 to 15.

Notes

• If you do not make any selections, for within about 65 seconds, or do press TUNE/MODE button during the initial setting mode, the setting mode will be canceled and the unit returns to the previous mode.
• If you press the LIGHT button for within about 65 seconds during the initial setting mode, the setting mode will be extended.
• If you cancel during initial setting mode, the value of the unit, wheel size and total distance entered will be erased. The unit will revert to the previous setting.
• The cycle-computer will not activate during the initial setting mode.
• If you press RADIO POWER to turn on the unit during the initial setting mode, the mode is canceled and the radio will activate.
• If you change the unit in the initial setting mode, the values showed in the total distance (odometer) setting mode will be automatically converted into the new setting unit. However, when you convert the unit from miles to kilometers, any value over 159 999.9km is shown as 159 999.9km.

Displaying data

While cycling, current speed is always displayed and updated every second.
