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 result in 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.

General Guide

• Press C to change from mode to mode.

• About 1.5 seconds after you enter the Dual Time Mode, Alarm Mode, or Hand

Setting Mode the hands will move the position that indicates the current setting of the mode. You cannot change to another mode while the hands are moving. To change to another mode, either press C before the hands start to move, or wait until the hands stop before pressing C.

• In the Timekeeping Mode (except when a setting screen is on the display), press B to illuminate the face of the watch.

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,

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

Radio-controlled Atomic 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 (Anthorn).

• See the information under “Signal Reception Troubleshooting” if you experience

problems with time calibration signal reception.

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 Time Zone, which is the time zone where you normally will use the watch. For more information, see “To specify your Home Time Zone” 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.

To specify your Home Time Zone

1. In the Timekeeping Mode, hold down A until the GMT

differential value starts to flash, which indicates the setting screen.

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

• The second hand will move at high speed to the 12

o’clock position, where it will stop.

• The DST indicator indicates that Daylight Saving Time (summer time) is turned on for the currently selected time zone.

2. Use B (+) to select the time zone you want to use as

your Home Time Zone.

• The following are the GMT differential values for major cities in the Western Europe time zones.

3. Press A to exit the setting screen.

• The second hand will advance at high speed to the correct position and resume normal movement from there.

• Normally, your watch should show the correct time as soon as you specify your Home Time Zone. 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.

• Selecting +0.0, +1.0, or +2.0 (+1.0, +2.0, or +3.0 while DST is turned on) as your Home Time Zone automatically turns on auto receive. When auto receive is turned on and you are within the reception range, the watch will receive the time calibration signal from the applicable transmitter automatically (in the middle of the night) and update its settings accordingly. For information about the relationship between time zones (GMT differential values) and transmitters, see “Transmitters”.

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

• If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.

• 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. 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.

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

• Time calibration signal reception takes from two 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 (Anthorn) time calibration signals.

See “Transmitters” for more information.

Approximate Reception Ranges

• 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)

• 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.

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 Time Zone, and whether standard time or Daylight Saving Time is selected for your Time Zone.

Note

• Auto receive is turned on whenever +0.0, +1.0, or +2.0 (+1.0, +2.0, or +3.0 while DST is turned on) is selected as the Home Time Zone.

+ 0.0 (DST +1.0)

+ 1.0 (DST +2.0)

+ 2.0 (DST +3.0)

Note

• Calibration signal reception is performed automatically whenever a calibration time is reached while the watch is in the Timekeeping Mode or Dual Time Mode. Note, however, that auto receive is not performed if a calibration time is reached in the following cases:

• 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 14 minutes every day when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing any button operation within 14 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.
