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

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,

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 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.

• The actual level at which some functions are disabled depends on the watch model.

• Frequent display illumination can run down the battery quickly and require charging.

The following guidelines give an idea of the charging time required to recover from a

single illumination operation.

Approximately 5 minutes exposure to bright sunlight coming in through a window

Approximately about 8 hours exposure to indoor fluorescent lighting

• Be sure to read “Power Supply” for important information you need to know

when exposing the watch to bright light.

If the display of the watch is blank...

If the display of the watch is blank, it means that the watch’s Power Saving function

has turned off the display to conserve power.

• See “Power Saving Function” for more information.

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).

• 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 City (the city where you normally will use the watch). For more

information, see “To specify your Home City”.

• 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 “To set the time

and date manually” for more information about manual time settings.

• 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 January 2008, 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.

To specify your Home City

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

seconds until the left dial hand points to T1 and the city

code flashes on the upper display. This is the setting

screen.

2. Press D (east) and B (west) to select the city code

you want to use as your Home City.

3. Press A twice 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

operation (in the middle of the night). You also can perform manual receive or you

can set the time manually.

• 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

“Important!” under “Time Calibration Signal Reception” and “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 (five times for the China signal). 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.

12 o’clock

• Make sure the watch is facing the right way.
