Getting Acquainted

Congratulations upon your selection of this CASIO watch. T o get the most out of your purchase, be sure to read this manual carefully.

• This watch does not have a time zone that corresponds to the Greenwich

Mean Time differential of -3.5 hours. Because of this, the radio-controlled timekeeping 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 cause some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. T o 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.

Charge

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

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

when exposing the watch 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,

Radio-controlled Atomic Timekeeping

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 in the United States (Fort Collins, Colorado).

• 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.

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.

• The first thing you should do after purchasing this watch is to specify your Home Time Zone, which is the time zone where you will normally use the watch. For more information, see “T o specify your Home Time Zone” below.

• When using the watch outside the range of the U.S. time signal transmitter, you have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.

3. Press A eight times to exit the setting mode.

• The watch will also return to the Timekeeping Mode if you do not perform any operation for about two or three minutes.

• Normally, your watch should show the correct time as soon as you specify your Home Time Zone. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You can also 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.

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 9 o’clock side facing towards a window. Make sure there are no metal objects nearby.

9 o’clock

• The watch should not be facing the wrong way.

Operation Guide 4383

• 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 four to seven minutes, but in some

cases it can take as long as 14 minutes. T ake care that you do not perform any button operations or move the watch during this time.

• This watch is designed to pick up the time calibration signal transmitted in the United States (Fort Collins, Colorado).

Reception Range

• At distances further than about 600 miles (1,000 kilometers) from the Fort Collins transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.

• Even when the watch is within the reception range of the transmitter, signal reception will be impossible if the signal is blocked by mountains or other geological formations between the watch and signal source.

• Signal reception is affected by weather, atmospheric conditions, and seasonal changes.

• See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

The watch starts to receive the time calibration signal automatically when the time in the Timekeeping Mode reaches 0:01 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch also will perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful. 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 Time Zone, and whether standard time or Daylight Saving Time is selected for your Home Time Zone.

Note

• The auto receive operation is performed only if the watch is in the Timekeeping Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while you are configuring settings.

• Auto receipt of the calibration signal is 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 four to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of 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. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time is actually the correct time.

To perform manual receive

Note

• To interrupt a receive operation and return to the Timekeeping Mode, press any button.

• If reception is not successful, the second hand will move to N (NO). One or two minutes later, the second hand will resume normal operation, without any adjustment of the hand setting.

• If the second hand is pointing to Y (YES) or N (NO), you can return to the Timekeeping Mode by pressing any button.

1.Place the watch on a stable surface so its 9 o’clock side is facing towards a window.

2.In any mode, hold down B for about two seconds until the watch beeps.

3.When you release B, the second hand will move to R

(READY) to indicate that the watch is setting up for time calibration reception.

• The second hand will move to W (WORK) and stay there

while actual reception is in progress.

• The hour and minute hands continue to keep time

normally.

• Time calibration signal reception takes from four to

seven minutes, but in some cases it can take up to 14 minutes. T ake care that you do not perform any button operations or move the watch during this time.

• If reception is successful, the second hand will move to

Y (YES). One or two minutes later, the hands will move to the correct time.

times.

• The current receive result is cleared when the first auto receive operation is performed on the following day. This means Y (YES) indicates successful signal reception since the start of the current day.

• Y (YES) continues to be indicated even if an attempt at manual receive fails after auto receive is successful.

• If you adjust the time or date setting manually, the second hand will move to N (NO).
