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 Greenwich

••

Mean Time differential 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 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.

Time/Date Adjustment

• Whenever you enter the Timekeeping, Countdown Timer, World Time, or Alarm Mode, the hands of the watch move to the applicable time for that mode. Even if the hands are moving, you can press C to move to another mode (except for the Stopwatch Mode), if you want. Note, however, that all other buttons are disabled while the hands are moving.

Radio-controlled Atomic Timekeeping

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

• Supported time calibration signals: Germany (Mainflingen), England (Anthorn), United States (Fort Collins), Japan (Fukushima or 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, which is 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 “Timekeeping” 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.

• In addition to the above, you also can select city codes that are outside the ranges of the time calibration signal transmitters supported by this watch.

• Note that this watch does not have a city code that corresponds to Newfoundland.

3. After the Home City setting is the way you want, press A to return to the

Timekeeping Mode.

• Normally, your watch should show the correct time as soon as you specify your Home City code. If it does not, it should adjust automatically after the next auto receive operation. You also can perform manual receive or you can set the time manually.

• Even if the time calibration signal is received correctly, there are some times when the analog hands may not indicate the correct time. If this happens, use the procedures under “Adjusting the Home Positions” to check the home positions of the hands, and make adjustments as required.

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time. The time calibration signals transmitted from Mainflingen (Germany), Anthorn (England), or Fort Collins (the United States) include both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the signals.

• Though the time calibration signal transmitted by the Fukushima and Fukuoka/Saga, Japan transmitters include summer time data, summer time currently is not implemented in Japan (as of 2007).

• The default DST setting is Auto DST (AT/AUTO) whenever you select LON, PA R, ATH , ANC, LAX, DEN, CHI, NYC, or TYO as your Home City code.

• If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually. For more information, see “To set the time and date manually”.

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. 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.

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

below.

Inside or among buildings

• Signal reception normally is 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 during this time.

• The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below. If you use the watch in Japan or Europe (each of which has two different transmitter locations), it will try to receive the time calibration signal from one of the transmitters in your current location. If it cannot receive the signal, it will then try to receive the time calibration signal from the other transmitter.

U.K. signal transmitter approximate reception range as of April 2007

• In April 2007, the U.K. signal transmitter was moved from Rugby to Anthorn, which resulted in a slight shift in the approximate reception range of the signal. The shift is so slight that there is virtually no change in the ability to receive the signal.

• Even when the watch is within the reception range of a transmitter, signal reception may be impossible at times due to the effects of geographic contours, structures, weather, the season of the year, the time of day, radio interference, etc. Note that the signal becomes weaker at distances of approximately 500 kilometers from the transmitter, which means that the influence of the conditions listed above becomes even greater.

About Auto Receive

The watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home City, and whether standard time or Daylight Saving Time is selected for your Home City.

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 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 receive the signal easily.

• The watch receives the calibration signal for two to 14 minutes every day when the time in the Timekeeping Mode reaches each of the calibration times. 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 the Timekeeping Mode.
