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

Solar cell

• 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.

Solar cell (Converts light to electrical power.)

Charge

Rechargeable battery

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.

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.

• 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.

• Make sure the watch is facing the right way.

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.

• The watch receives the calibration signal for two to 14 minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within 14 minutes before or after the calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the current time in your Home City, as kept in the Timekeeping Mode.

Swapping your Home City and World Time City

You can use the procedure below to swap your Home City and World Time city. This changes your Home City to your World Time city, and your World Time city to your Home City. This capability can come in handy when you frequently travel between two cities in different time zones.

• If your current World Time city supports receipt of a time calibration signal, making it your Home City enables calibration signal reception.

• For information about which cities support time calibration signal reception, see “To specify your Home City”.

To swap your Home City and World Time city

1. In the World Time Mode, use D to select the World Time city you want.

2. Hold down A and B until the watch beeps.

• This will make the World Time city (which you selected in step 1), your Home City. At the same time, it changes the Home City you had selected prior to step 2 your World Time city.

• After swapping the Home City and World Time city, the watch stays in the World Time Mode with the city that was selected as the Home City prior to step 2 now displayed as the World Time city.

World Time shows the current time in 48 cities (29 time zones) around the world. A simple operation swaps your Home City with the currently selected World Time city.

• The times kept in the World Time Mode are synchronized with the time being kept in the Timekeeping Mode. If you feel that there is an error in any World Time Mode time, check to make sure you have the correct city selected as your Home City. Also check to make sure that the current time as shown in the Timekeeping Mode is correct.

• Select a city code in the World Time Mode to display the current time in any particular time zone around the globe. See the “City Code Table” for information about the UTC offset settings that are supported.
