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

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. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Battery charges in the light.

Solar cell (Converts light to electrical power.)

Solar cell

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. Even if the face of the watch is only partially blocked from light, charging will be reduced significantly.

Chinese Time Calibration Signal

The Chinese time calibration signal (BPC) is maintained by the National Time Service Center (http://www.ntsc.ac.cn/) of the Chinese Academy of Sciences, and is transmitted from a transmitter (68.5 kHz) located in Shangqiu. The time data of the Chinese time calibration signal is maintained by the National Time Service Center.

• Note that transmission of the calibration signal may be interrupted occasionally due to maintenance, lightning, etc.

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

• This watch is designed to receive the time calibration signal transmitted from Shangqiu City, Henan Province, China (Call Sign: BPC, Frequency: 68.5 kHz).

• As of July 2007, 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.

• 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.

• When using the watch in an area the Chinese time calibration signal does not reach or outside the China time zone (GMT +8), you will need to adjust the watch’s time setting manually. For information about adjusting the time setting manually, see “Timekeeping”.

• The watch interprets any manual change of the time setting by more than 30 minutes or manual switching between Standard Time and Daylight Saving time as a change to another time zone. At this time the watch turn off auto receive automatically.

• If you successfully perform a manual receive operation after auto receive is turned off automatically by one of the events described above, the watch will turn auto receive back on automatically.

• 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.

Operation Guide 5019

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 five 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. Take

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

Approximate Reception Range

500 km

• 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.

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

About Auto Receive

The watch starts to receive the time calibration signal automatically when the time in the Timekeeping Mode reaches 1:00 a.m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m. each day (calibration times). When any auto receive is successful, the remaining auto receive operations are not performed.

Note

• Auto receive is supported in all modes except while a stopwatch elapsed time operation is in progress.

• 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 seven minutes every day 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.

To perform manual receive

Second hand

Day hand

Note

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

• If reception is not successful, the day hand will move to N. Five seconds later, the day hand will resume normal operation, without any adjustment of the hand setting.

Viewing the Latest Signal Reception Results

You can use the procedure below to check whether or not the last signal receive operation was successful.

1. Place the watch on a stable surface so its 12 o’clock side is facing towards a window.

2. In the Timekeeping Mode, hold down B for about two seconds until the day hand moves to R. This will cause the watch to prepare for signal reception.

• At this time the second hand will move to 60

and stop.

• The day hand will move to W and stay there

while actual reception is in progress.

• If signal reception is unstable during reception,

the day hand may move between W and R.

• The hour and minute hands continue to keep

time normally during manual receive.

• 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.

• If reception is successful, the day hand will

move to Y. Five seconds later, the hands will move to the correct time.

To check the latest signal reception results

Day hand

• Y 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 day hand will move to N.

In the Timekeeping Mode, press B.

• If the watch was able to perform a successful signal receive operation since midnight, the day hand will move to Y. If the watch has been unable to receive any signal successfully, the day hand will move to N.

• The watch will return to the Timekeeping Mode after five seconds or when you press B.

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