Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

Keep the watch exposed to bright light

Bright light

• The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will cause some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Battery charges in the light. Battery discharges in the dark.

Charge

• The actual level at which some functions are disabled depends on the watch model.

• Be sure to read “Power Supply” for important information you need to know

when exposing the watch to bright light.

The electricity generated by the solar cell of the watch is

stored by a built-in battery. Leaving or using the watch

where it is not exposed to light causes the battery to run down. Make sure the watch is exposed to light as much as possible.

• When you are not wearing the watch on your wrist,

position the face so it is pointed at a source of bright light.

• You should try to keep the watch outside of your sleeve as much as possible. Even if the face of the watch is only partially blocked from light, charging will be reduced significantly.

If the analog hands aren’t moving, it means that the power saving mode has stopped them to save battery power.

• See “Power Saving” for more information.

• The hands also stop whenever the battery level reaches Level 3.

Your watch switches automatically between Standard Time and Daylight Saving Time (summer time). Note, however, that switching cannot be performed correctly if the watch is not able to receive the time calibration signal. If you notice that the current time is not displayed properly, use the procedure under “To perform manual receive” or “To set the time and date manually” to correct it.

Radio-controlled Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.

• Supported time calibration signals: Germany (Mainflingen), England (Rugby).

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You can also 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, which is the city where you will normally use the watch. For more information, see “To specify your Home City” below.

• When using the watch outside the range of the time signal transmitter, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.

1. In the Timekeeping Mode, hold down A for about five

seconds until the stopwatch second hand moves to the currently selected GMT differential value and stops. This is the setting mode.

• The GMT differential value indicates the time difference in hours between Greenwich Mean Time and the currently selected city code.

2. Press D to select the city codes you want to use as

your Home City.

• The following are the city codes for major cities in the Western Europe time zones.

Milan, Rome, Madrid, Amsterdam, Algiers, Hamburg, Frankfurt, Vienna, Stockholm, Berlin

Cairo, Jerusalem, Helsinki, Istanbul, Beirut, Damascus, Cape Town

3. Press A to return to the Timekeeping Mode.

• The watch will also return to the Timekeeping Mode if you do not perform any operation for about two or three minutes.

• Normally, your watch should show the correct time as soon as you specify 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 can also perform manual receive or you can set the time manually.

• Even if the time calibration signal is received correctly, there are some times when the analog hands may not indicate the correct time. If this happens, use the procedures under “Adjusting the Home Positions” to check the home positions of the hands, and make adjustments as required.

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. 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 facing towards a window. Make sure there are no metal objects nearby.

12 o’clock

• Make sure the watch is facing the right way.

Operation Guide 4365

• Proper signal reception can be difficult or even impossible under the conditions listed below.

Inside or among buildings

• Signal reception is normally better at night than during the day.

• Time calibration signal reception takes from four to seven minutes, but in some

cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

• 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.

• 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 Rugby (England) transmitters: 500 kilometers (310 miles)

• Even when the watch is within the reception range of the transmitter, signal reception will be impossible if the signal is blocked by mountains or other geological formations between the watch and signal source.

• Signal reception is affected by weather, atmospheric conditions, and seasonal changes.

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

About Auto Receive

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

Note

• Auto receive is turned on whenever LON, PAR, or ATH is selected as the Home City code.

LON Standard Time (GMT +0)

PAR (GMT +1)

ATH Standard Time (GMT +2)

Note

• Auto receive is supported in all modes except while a stopwatch elapsed time operation is in progress.

• 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.

• The watch receives the calibration signal for two to 14 minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing any button operation within ten 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 current time in the Timekeeping Mode.

Signal Reception Troubleshooting

Check the following points whenever you experience problems with signal reception.

1. In the Timekeeping Mode, press A.

• If the watch was able to perform a successful signal receive operation since midnight, the stopwatch second hand will move to Y (YES). If the watch has been unable to receive any signal successfully, the second hand will move to N (NO).

• The watch will return to the Timekeeping Mode after five seconds or when you press A.

• The current receive result is cleared when the first auto receive operation is performed on the following day. This means Y (YES) indicates successful signal reception since the start of the current day.
