Timekeeping Mode

Press C.

Radio-controlledAtomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.

This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga).

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.

The first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see “To specify your Home City”.

When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.

The U.S. time calibration signal can be picked up by the watch while in North America. The term “North America” in this manual refers to the area that consists of Canada, the continental United States, and Mexico.

As of December 2009, 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 that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.

3. Press Ato exit the setting screen.

Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You also can perform manual receive or you can set the time manually.

The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Important!” under “Time Calibration Signal Reception” and “Transmitters”.

See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.

You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.

Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow),HNL (Honolulu), andANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off”.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.

Auto Receive

With auto receive, the watch receives the time calibration signal automatically up to six times a day (five times a day for the Chinese calibration signal). When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive”.

Manual Receive

Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.

Important!

When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side pointing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.

Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.

The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within seven minutes before or after the calibration times. Doing so can interfere with correct calibration.

Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.

About the Signal Strength Indicator

The signal strength indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest. The signal strength indicator is displayed while an auto or manual receive operation is in progress.

Signal strength indicator

 

Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the signal strength indicator to indicate signal strength.

Use the signal strength indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.

Following reception of the time calibration signal and calibration of the watch’s time setting, the RCVD indicator will remain on the display in all modes. TheRCVD indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

The RCVD indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.

The RCVD indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that theRCVD indicator disappears from the display each day when the first auto receive operation of the day is performed.

Illumination

 

 

 

 

 

 

 

 

 

This watch has an EL (electro-luminescent)panel that

 

 

 

 

 

 

 

 

causes the entire display to glow for easy reading in the

 

 

 

 

 

 

 

 

dark. The watch’s auto light switch turns on illumination

 

 

 

 

 

 

 

 

automatically when you angle the watch towards your

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

face.

 

 

 

 

 

 

 

 

The auto light switch must be turned on (indicated by

 

 

 

 

 

 

 

 

the auto light switch on indicator) for it to operate.

information about using illumination.

 

 

 

 

 

 

 

 

To illuminate the display manually

In any mode (except when a setting screen is on the display), press B to turn on illumination.

The above operation turns on illumination regardless of the current auto light switch setting.

About the Auto Light Switch

Turning on the auto light switch causes illumination to turn on, whenever you position your wrist as described below in any mode. Note that this watch features a “Full Auto EL Light”, so the auto light switch operates only when available light is below a certain level. It does not turn on the backlight under bright light.

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.

Wear the watch on the outside of your wrist.

Warning!

Always make sure you are in a safe place whenever you are reading the display of the watch using the auto light switch. 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 the auto light switch does not startle or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury.

To turn the auto light switch on and off

In the Timekeeping Mode, hold down Bfor about three seconds to toggle the auto light switch on (A.EL displayed) and off (A.EL not displayed).

The auto light switch on indicator is on the display in all modes while the auto light switch is turned on.

Power Supply

This watch is equipped with a solar cell and a rechargeable battery that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.

Example: Orient the watch so its face is

Solar cell

pointing at a light source.

 

The illustration shows how to position a

 

watch with a resin band.

 

Note that charging efficiency drops when

 

any part of the solar cell is blocked by

 

clothing, etc.

 

You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is

covered only partially.

Important!

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 rechargeable battery power to run down. Be sure that the watch is exposed to bright light whenever possible.

This watch uses a rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.

Never try to remove or replace the watch’s rechargeable battery yourself. Use of the wrong type of battery can damage the watch.

All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.

Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

Function Status

All functions enabled.

All functions enabled.

Auto and manual receive, illumination, and beeper disabled.

Except for timekeeping and the CHG (charge) indicator, all functions and display indicators disabled.

All functions disabled.

The flashing LOW indicator at Level 3 tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.

At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the current time, date, and other settings.

The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5. With this Home City code setting, the watch is configured to receive the time calibration signals of Japan. If you are using the watch in North America, Europe, or China, you will need to change the Home City code setting to match your location whenever the battery drops to Level 5.

Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.

Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.

Charging Precautions

If you use the light or alarms a number of times during a short period, all segments of the battery power indicator flash and the following operations become temporarily disabled as battery power recovers.

-Display illumination

-Alarm and hourly time signal

-Time calibration signal reception

After some time, the battery power indicator should stop flashing to indicate that battery power is back to normal. At this time the watch should return to normal operation.

If the battery power indicator frequently flashes, it means that battery power is low. Leave the watch in bright light to allow it to charge.

Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.

Warning!

Leaving the watch in bright light to charge its rechargeable battery 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
