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

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

l	l	l	l	l	l	l	l	l	l	l	where it is not exposed to light causes the battery to run

Solar cell											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. Charging is reduced significantly if
											the face is only partially covered.

• 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 Atomic Timekeeping

PM indicator

DST indicator

Hour : Minutes : Seconds

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 Fort Collins, Colorado (USA). Reception is possible within North America*.

*The term “North America” in this User’s Guide refers to the area that consists of Canada, the continental United States, and Mexico.

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.

Important!

•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 operation (in the middle of the night). You also can 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.

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 picks up the time calibration signal automatically six

times a day at midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m.

For more information, see “About Auto Receive”.

• Manual Receive

•The first thing you should do after purchasing this watch is to set your Home City, which is the city where you normally will use the watch. For more information, see “To set your Home City” below.

•When using the watch outside of the range of the transmitter in Fort Collins, you need to adjust the time manually as required. See “Timekeeping” for information about manual settings.

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.
