When within range of the applicable transmitter, this watch can receive either the Germany (Mainflingen) or England (Rugby) time calibration signals.

See “Transmitters” for more information.

1,500 kilometers

Rugby

 

500 kilometers

Mainflingen

 

This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany. Signal reception is possible within the area represented by a circle with a radius of about 1,500 kilometers.

At distances further than about 500 kilometers from a transmitter, signal reception may not be possible during certain times of year or times of day. Radio interference may also cause problems with reception.

See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

With auto receive, the watch receives the time calibration signal automatically five or six times a day. When the second or third receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home City Code, and whether standard time or Daylight Saving Time is selected for your Home City Code.

Note

Auto receive is turned on whenever LON,PAR,BER, orATH is selected as the Home City code. For information about turning off auto receive, see “To select the transmitter mode”.

Note

Auto receive works only while the watch is in the Timekeeping Mode or World Time Mode. Auto receive is not performed if an auto receive time is reached while an alarm is sounding, while a countdown timer operation is in progress, or if a setting screen (a screen with a flashing setting) is on the display.

Auto receipt 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.

When auto receive is turned on, the watch receives the calibration signal for two to six minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Do not perform any button operation within six minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

Remember that reception of the calibration signal depends on the time kept 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 Timekeeping Mode time is actually the correct time.

If more than one auto receive is successful, the watch uses the data from the last successful receive to adjust settings. When only one reception is successful, the watch uses the data of the successful reception.

About the Receiving Indicator

The receiving 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.

Receiving indicator

Weak

Strong

(Level 1)

(Level 4)

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

Use the receiving 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 Level 4 receiving indicator will remain on the display in all modes. The Level 4 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

The Level 4 receiving 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 Level 4 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at the next successful reception each day.

To perform manual receive

1. Place the watch on a stable surface so its top (12 o’clock side) is facing towards a window.

2. In the Timekeeping Mode, hold down Dfor about two seconds until the watch beeps.

Release Dand the messageRC! appears to indicate

that signal reception has started.

Time calibration signal reception takes from two to six minutes. Take care that you do not perform any button operations or move the watch during this time.

After signal reception is complete, the display of the watch changes to the Last Signal screen.

Note

To interrupt a receive operation and return to the Timekeeping Mode, press D.

If the receive operation is unsuccessful, the message ERR appears on the display for about one or two minutes. After that, the watch returns to the Timekeeping Mode.

You can also change from the Last Signal or ERR screen to the normal timekeeping screen by pressing D.

Illumination

Auto light switch indicator

The 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 illuminates the display automatically when you angle the watch towards your face.

The auto light switch must be turned on (indicated by the auto light switch indicator) for it to operate.

See “Illumination Precautions” for other important information.

To turn on illumination manually

In any mode, press Lto illuminate the display.

You can specify 1.5 seconds or 2.5 seconds as the illumination duration. See “To set the time and date” for more information.

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 illuminate the display under bright light.

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

Wear the watch on the outside of your wrist.

Parallel to

More than

ground

40°

Warning!

Always make sure you are in a safe place whenever you are reading 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 on 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 any mode, hold down Lfor about two seconds to toggle the auto light switch on (auto light switch indicator displayed) and off (auto light switch indicator not displayed).

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

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary 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

Solar cell

is 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 only partially covered.

Operation Guide 2972 2973

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. Make sure that the watch is normally exposed to bright light whenever possible.

This watch uses a special 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 special rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.

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

The current time and all other settings return to their initial factory defaults whenever battery power drops to Level 4 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.

The flashing charge indicator ( CHG ) 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 4, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 3 (indicated by the flashing charge indicator) from Level 4. You will not be able to configure any of the other settings until the battery reaches Level 2 (no charge indicator) after dropping to Level 4.

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

If you use the light or alarms a number of times during a short period, the recover indicator (RECOV) appears and the following operations become disabled until battery power recovers.

Illumination Beeper tone

After some time, battery power will recover and the recover indicator will disappear, indicating that the above functions are enabled again.

Charging Precautions

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.

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

The time calibration signals transmitted from Rugby and Mainflingen includes both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the Rugby and Mainflingen signals.

The default DST setting is Auto DST (A) whenever you selectLON,PAR,BER, orATH as your Home City code.

If you experience problems receiving the time calibration signal in your area, it is probably best to switch between Standard Time and Daylight Saving Time (summer time) manually.

To change the Daylight Saving Time (summer time) setting

1.In the Timekeeping Mode, hold down Auntil the city code starts to flash, which indicates the setting screen.
