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.

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.

• This watch switches automatically between Standard Time and Daylight Saving Time in accordance with the time calibration signal it receives. There is no indicator showing whether the time currently shown by the watch is Standard Time or Daylight Saving Time.

• This watch is designed to pick up the time calibration signal transmitted in Germany (Mainflingen) and 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, when necessary.

• The first thing you should do after purchasing this watch is to specify a GMT differential, which is the time differential between GMT and the location where you normally will use the watch. For more information, see “To specify a GMT differential” below.

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

To specify a GMT differential

value (+1)

• Normally, your watch should show the correct time as soon as you select a GMT differential. 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.

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

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

GMT differential value (+2)

• The GMT differential value indicates the time difference in hours from Greenwich Mean Time.

2. Use A to move the second hand to the GMT

differential setting you want to use.

GMT +0 (12 o’clock): London GMT +1 (1 o’clock): Paris, Berlin, Milan, Rome,

Amsterdam, Hamburg, Frankfurt, Vienna, Barcelona, Madrid

GMT +2 (2 o’clock): Athens

3. Press B to exit the setting mode.

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

• 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 GMT differential values and transmitters, see “Transmitters”.

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

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.

Operation Guide 4325 4326

• 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

1,500 kilometers

Anthorn

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 also may cause problems with reception.

• 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 the currently selected GMT differential, and whether standard time or Daylight Saving Time is selected for it.

GMT Differential Auto Receive Start Times

GMT +0 Standard Time 1:00 am 2:00 am 3:00 am 4:00 am 5:00 am Midnight

Daylight 4:00 am 5:00 am Midnight 1:00 am 2:00 am 3:00 am Saving Time next day next day next day

Note

• The auto receive operation is performed only if the watch is in the Timekeeping Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while you are configuring settings.

• 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 seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven 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. 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.

To adjust the time setting manually

Use the Timekeeping Mode to set and view the current time. This section also explains how to set the current time manually.

• If you become confused and lose your way during the following procedures, simply put the watch down and do not perform any button operation for two or three minutes. This will cause the watch to enter the Timekeeping Mode (indicated by normal one-second movement of the second hand) automatically. After that, you can try performing the manual setting procedure again from the beginning.

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

seconds.

• This operation causes the second hand to move to AM or

PM in accordance with the current time setting. This is the setting mode.

• The hour and minute hands do not move in the setting mode.

2. Press B to move the time setting forward by one minute.

• Holding down B for about two seconds starts high-speed hand movement. High-speed hand movement will continue until the hands complete a 12-hour cycle, or until you stop them by pressing B.

• If you exit the setting mode after changing the time setting, the second hand will restart timing from 12 o’clock (0 seconds) automatically.

• The AM/PM setting will not change even if you move the hour hand past 12 o’clock in step 2. Use step 3 below to switch between AM and PM.
