Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to carefully read this manual and keep it on hand for later reference when necessary.

••

• 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 and World Time functions will not display the correct time for Newfoundland, Canada.

Expose the watch to bright light to charge its battery before using it.

You can use this watch even as its battery is being charged by exposure to bright light.

• Be sure to read “Battery” of this manual for important information you need to know when exposing the watch to bright light.

About This Manual

If the Power Saving indicator (PS) is flashing on the display, it means that the display is blank because the watch’s Power Saving function has turned it off to conserve power. Power Saving automatically turns off the display and enters a sleep state whenever your watch is left for a certain period in an area where it is dark. If the watch is kept in the dark for a longer period, the analog hands will also stop moving after a few days.

• The initial factory default setting is Power Saving on.

• The watch will recover from the sleep state if you move it

to a well-lit area or if you press any button.

• See “Power Saving Function” for more information.

• Button operations are indicated using the letters shown

in the illustration.

• Each section of this manual provides you with the information you need to perform operations in each mode. Further details and technical information can be found in the “Reference” section.

Current Time Setting

This watch automatically adjusts its time setting 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 set your Home City, which is the city where you will normally use the watch. For more information, see “To set your Home City” below.

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

• The analog time of this watch is synchronized with the digital time. Because of this, the analog time setting is automatically adjusted whenever you change the digital setting. See “Analog Timekeeping” for more information.

4. Press A twice to exit the setting screen.

• The first press of A displays the 12/24-hour setting screen. Pressing A again exits the setting screen.

• The second hand will advance at high speed to the correct position in accordance with seconds count of the digital time, and resume normal movement from there.

• 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 (in the middle of the night). You can also perform manual receive or you can set the time manually.

• If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.

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

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) and the time calibration signals transmitted in Japan.

• 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.

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

• Manual Receive

Last Signal Screen

With auto receive, the watch automatically picks up the time calibration signal five times a day at 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more information, see “About Auto Receive”.

Manual receive lets you start time calibration signal reception with the press of a button. For more information, see “To perform manual receive”.

• Signal reception is normally better at night than during the day.

• Time calibration signal reception takes from two to seven minutes. Take care that

you do not perform any button operations or move the watch during this time.

• When within range of the applicable transmitter, this watch can receive either the U.S. (Fort Collins, Colorado) or Japanese (Fukushima or Fukuoka/Saga) time calibration signal. The signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

Fukuoka/Saga

• Under good reception conditions, signal reception is possible within a radius of about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.

• 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.

• At distances further than about 500 kilometers from the Fukushima and Fukuoka/ Saga transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.

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

About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches 0:00 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 will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive are successful.

Note

• Auto receive is performed only if the watch is in the Timekeeping Mode or World Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while an alarm is sounding, or while you are configuring settings (while settings are flashing on the display).

• When a reception starts, the second hand will move at high speed to the 12 o’clock position where it will stop until the reception is complete.

• 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 easily receive the signal.

• When auto receive is turned on, the watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the five calibration times. Do not perform any button operation within seven minutes before or after any of the five calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the time kept in the digital display. The reception will be performed whenever the display shows one of the five calibration times, regardless of whether or not the displayed time is actually the correct time.

• When two, three, four, or five receptions are successful, the watch uses the data of the last reception for calibration. When only one reception is successful, the watch uses the data of the successful reception.

About the Receiving Indicator

The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest.

Receiving indicator

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.

• Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal reception.

• The Level 4 receiving indicator appears on the Timekeeping Mode’s Receiving Indicator and Seconds Count screen only. The Level 4 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.

• The Level 4 receiving indicator indicates that at least one of the five calibration signal reception was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at 3:00 a.m. each day.
