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 and keep it on hand for later reference when necessary.

Expose the watch to bright light to charge its batteries before using it.

You can use this watch even as its batteries are being charged by exposure to bright light.

• Be sure to read “Power Supply” of this manual for important information you need to know when exposing the watch to bright light.

General Guide

• Press C to change from mode to mode.

• In any mode, press L to illuminate the digital dials.

If the Power Saving indicator ( ) is flashing on the top dial, it means that the digital dials are blank because the watch’s Power Saving function has turned them off to conserve power. Power Saving automatically turns off the digital dials and enters a sleep state whenever your watch is left for a certain period in an area where it is dark. If the watch is kept in the dark for a longer period, the analog hands will also stop moving after a few days.

• The initial factory default setting is Power Saving on.

• The watch will recover from the sleep state if you move it

to a well-lit area, if you press any button, or if you angle the watch towards your face for reading.

• See “Power Saving Function” for more information.

Current Time Setting

This watch automatically adjusts its time setting 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 set your Home City, which is the city where you will normally use the watch. For more information, see “To set your Home City” below.

• When using the watch in an area that is outside of the range of the transmitters in Rugby and Mainflingen, you need to manually adjust the time as required. See “Timekeeping” for information about manual settings.

• The analog time of this watch is synchronized with the digital time. Because of this, the analog time setting is automatically adjusted whenever you change the digital setting. See “Analog Timekeeping” for more information.

3. Press A to 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 (in the middle of the night). You can also perform manual receive or you can set the time manually.

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

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 is designed to pick up the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany.

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

code starts to flash in the bottom dial, which indicates the setting screen.

2. Use D (east) and B (west) to scroll through the city

codes until the one you want to use as your Home City is displayed.

• The following are the city codes for major cities in the

Western Europe time zones.

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 automatically picks up the time calibration signal five times a day at midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more information, see “About Auto Receive”.

• Manual Receive

Manual receive lets you start a time calibration signal reception 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.

• The watch should not be on its side or facing the wrong way.

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

below.

Operation Guide 3360 3361

• Signal reception is normally 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 while time calibration signal reception is in progress.

1,500 kilometers

Rugby

500 kilometers

• 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

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful.

Note

• Auto receive is performed only if the watch is in the Timekeeping Mode or World Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while an alarm is sounding, or while you are configuring settings (while a setting is flashing in a digital dial).

• 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 easily receive the signal.

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

• Remember that reception of the calibration signal depends on the digital time kept by the Timekeeping Mode. Reception will be performed whenever the Timekeeping Mode time reaches one of the five calibration times, regardless of whether or not the Timekeeping Mode time is actually the correct time.

• When two, three, four, or five receptions are successful, the watch uses the data of the last reception for calibration. 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 0)

• 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 reception.

• The Level 3 receiving indicator remains displayed on the top dial in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The Level 3 receiving indicator is not displayed on the top dial if signal reception was unsuccessful or after manual adjustment of the current time setting.

• The Level 3 receiving indicator indicates that at least one of the five calibration signal receive operations was successful. Note, however, that the Level 3 receiving indicator is cleared at 3:00 a.m. each day.
