Casio 5130 (OC) Operation Manual

MA1003-EA
Congratulations upon your selection of this CASIO watch.
This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of
this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland,
Canada.
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by
you or any third party arising through the use of this product or its malfunction.

This User's Guide uses numbers shown above to identify watch hands and
indicators.
Things to check before using the watch
1. Hold down C at least two seconds to enter regular timekeeping, and then observe the
movement of the x Second Hand.
Is the x Second Hand moving smoothly at one-second intervals?
NO
Is the x Second Hand moving at two-second intervals
or is it stopped completely?
YES
Power is low. Charge the watch by placing it in a
location where it is exposed to light. For details, see

"Charging the Watch".

2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under "To configure Home City settings" to configure your Home City and daylight
saving time settings.
Important!
Proper time calibration signal reception and World Time settings depend on correct Home City, Home
Time, and Home Date settings. Make sure you configure these settings correctly.
3. Set the current time.
• To set the time using a time calibration signal
See "To get ready for a receive operation".
• To set the time manually
See "Configuring Current Time and Date Settings Manually".
The watch is now ready for use.
•
For details about the watch's radio controlled timekeeping feature, see "Radio Controlled Atomic
Timekeeping".
Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not
wearing the watch, leave
it in a location where it is
exposed to light.
• Best charging
performance is achieved
by exposing the watch to
light that is as strong as
possible.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot. Take care when
handling the watch to avoid burn injury. The watch can become particularly hot when exposed to
the following conditions for long periods.
• On the dashboard of a car parked in direct sunlight
•
Too close to an incandescent lamp
• Under direct sunlight
Important!
• Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps
to ensure that power does not run down.
• Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to
bright light whenever possible.
Power Levels
You can get an idea of the watch's power level by observing the movement of
the x Second Hand.
• If the x Second Hand is moving normally at one-second intervals, power is
at Level 1.
• If the x Second Hand is moving at two-second intervals, power is at Level
2, which is quite low. Expose the watch to light as soon as possible so it
can charge.

YES
The watch is charged sufficiently. For details
about charging, see "Charging the Watch".
NEXT
Go to step 2.
When wearing the watch, make
sure that its face is not blocked
from light by the sleeve of your
clothing.
• The watch may enter a sleep
state if its face is blocked by
your sleeve even only partially.
Function Status
All functions enabled
Time calibration signal reception
disabled
All functions disabled
•
When power drops to Level 3, all functions will be disabled but the watch will continue to keep time
internally for about one week. If you recharge the battery sufficiently during this period, the analog
hands will move automatically to the correct setting and regular timekeeping will resume. After one
week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
Charging Times

Outdoor sunlight (50,000 lux)
Window sunlight (10,000 lux)
Window sunlight on cloudy day (5,000 lux)
Indoor fluorescent lighting (500 lux)
* 1 Approximate exposure each day to generate power for normal daily operation
* 2 Approximate exposure to take power up one level
• The above times are for reference only. Actual times depend on lighting conditions.
• For details about the operating time and daily operating conditions, see the "Power Supply" section of
the Specifications.
Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area
where it is dark. The table below shows how watch functions are affected by Power Saving.
• There actually are two sleep state levels: "second hand sleep" and "function sleep".
Elapsed Time in Dark Operation
60 to 70 minutes (second hand sleep) x Second Hand only stopped at 12 o'clock, all other functions enabled
• All functions, including analog timekeeping, disabled
6 or 7 days (function sleep)
• Internal timekeeping maintained
• The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
To recover from the sleep state
Move the watch to a well-lit area or press any button.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See "Configuring Current Time and Date Settings Manually" for more information.
This section explains how the watch updates its time settings when the city code selected as the Home
City is in Japan, North America, Europe, or China, and is one that supports time calibration signal
reception.
If your Home City Code setting is this:
LONDON (LON), PARIS (PAR), ATHENS (ATH)
HONG KONG (HKG)
TOKYO (TYO)
HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX),
DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC)
Important!
• The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
• When HONOLULU (HNL) or HONG KONG (HKG) is selected as the Home City, only the time and date
are adjusted according to the time calibration signal. You need to switch manually between standard
time and daylight saving time (DST) if required. See "To configure Home City settings" for information
about how to do this.

Even when the watch is within range of a transmitter, signal reception may be impossible due to the
effects of geographic contours, structures, weather, the time of year, the time of day, radio interference,
etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the
influence of the above conditions becomes even greater.
• Signal reception may not be possible at the distances noted below during certain times of the year or
day. Radio interference may also cause problems with reception.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
−
− Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
− Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
Shangqiu (China) transmitter: 500 kilometers (310 miles)
−
• As of January 2010, China does not use Daylight Saving Time (DST). If China does go to the Daylight
Saving Time system in the future, some functions of this watch may no longer operate correctly.
•
Using this watch in a country covered by a time calibration signal that is different from the countries it
supports may result in incorrect time indication due to local application of summer time, etc.
