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.

General Guide

• Press C to change from mode to mode.

• In any mode (except when a setting screen is on the display), press B to illuminate

the display for about one second.

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.

Important!

• 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 can also 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 “Home City Codes and Transmitters”.

• Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow), HKG (Hong Kong), BJS (Beijing), HNL (Honolulu), and ANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off”.

• You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.

• See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.

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

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. Make sure there are no metal objects nearby.

• Make sure the watch is facing the right way.

Operation Guide 3089

• 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 one to 13 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.

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 one to 13 minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing any button operation within 13 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 actually is the correct time.

• Calibration signal reception is disabled while a countdown timer operation is

in progress.

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

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

• 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.

During signal reception, a transmitter indicator will flash to show you which signal is currently being received by the watch. After signal reception is complete, the indicator of the transmitter from which the signal was received will remain on, without flashing.

• The following shows the meaning of each of the transmitter indicator names.

JP40: Fukushima (Japan) JP60: Fukuoka/Saga (Japan) US60: Fort Collins, Colorado (the United States) GE77.5: Mainflingen (Germany) UK60: Anthorn (England)

• The transmitter indicator turns off automatically at the start of the first auto receive operation of a new day. The time of the first auto receive operation of a new day depends on your currently selected Home City.

1. Enter the Timekeeping Mode.

2. Place the watch on a stable surface so its 12 o’clock

side is facing towards a window.

3. Hold down D for about two seconds until RC! appears

on the display.

• The indicator of the transmitter whose signal the watch is attempting to receive will flash.

• Time calibration signal reception takes from one to 13 minutes. Take care that you do not perform any button operations or move the watch during this time.

• If the receive operation is successful, the reception date and time appear on the display, along with the GET indicator. The indicator of the transmitter whose signal the watch received will also be indicated. The watch will enter the Timekeeping Mode if you press D or if you do not perform any button operation for about two or three minutes.

• If the current reception fails but a previous reception was successful, the display shows the previous reception’s date and time, and the ERR indicator.

- - : - - indicates that none of the reception operations were successful. The watch will enter the Timekeeping Mode without changing the time setting if you press D or if you do not perform any button operation for about two or three minutes.

1. In the Timekeeping Mode, press D to display the Last

Signal screen.

2. Hold down A for about two seconds until RCV

appears on the display.

• The current auto receive setting (on or OFF) will flash.
