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.

•This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.

Keep the watch exposed to bright light

			Bright Light					The electricity generated by the solar cell of the watch is
								stored by a rechargeable battery. Leaving or using the
	l						l
		l	l l l	l	l l l	l		watch where it is not exposed to light causes the battery
	Solar cell							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. Charging is reduced significantly if
								the face is covered only partially.

•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.

•The U.S. time calibration signal can be picked up by the watch while in North America. The term “North America” in this manual refers to the area that consists of Canada, the continental United States, and Mexico.

•As of March 2010, China does not use Daylight Saving Time (DST). If China does go to the Daylight Saving Time system in the future, some functions of this watch may no longer operate correctly.

•Using this watch in a country covered by a time calibration that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.

To specify your Home City

1.In the Timekeeping Mode, hold down A for about three seconds. You can release the button after “ADJ” appears on the display.

•At this time, “12H” (12-hour timekeeping) or “24H” (24hour timekeeping) also will be flashing on the display.

E-12

4. Press Ato 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 operation (in the middle of the night). You also can perform manual receive (page E-25) or you can set the time manually (page E-54).

•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 city codes and transmitters, see page E-18 and “Transmitters” (page E-72).

•See the maps under “Approximate Reception Ranges” (page E-19) for information about the reception ranges of the watch.

•You can disable time signal reception, if you want. See “To turn auto receive on and off” on page E-27 for more information.

•Under factory default settings, auto receive is turned off for all of the following city codes: HNL (Honolulu) and ANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off” on page E-27.

E-14

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 pointing 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.

12 o’clock

or

• Make sure the watch is facing the right way.

E-16

•The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

	Home City Code	Transmitter	Frequency
	LON, PAR, ATH	Anthorn (England)	60.0 kHz
		Mainflingen (Germany)	77.5 kHz
	HKG	Shangqiu City (China)	68.5 kHz
	TYO	Fukushima (Japan)	40.0 kHz
		Fukuoka/Saga (Japan)	60.0 kHz
	HNL*, ANC*, LAX,	Fort Collins, Colorado	60.0 kHz
	DEN, CHI, NYC	(the United States)

* The areas covered by the HNL and ANC city codes are quite far from the time calibration signal transmitters, and so certain conditions may cause problems with signal reception.

• Calibration signal reception is disabled while a countdown timer operation is in progress.

Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.

•This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga).

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 City (the city where you normally will use the watch). For more information, see “To specify your Home City” (page E-12).

•When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See “Timekeeping” (page E-53) for more information about manual time settings.

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 6 times a day (5 times a day for the Chinese calibration signal). When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive” (page E-22).

• 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” (page E-25).

Note

•When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.

•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.

•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.
