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.

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-configurewatch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

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

Supported time calibration signals: Germany (Mainflingen), England (Rugby), United States (Fort Collins), Japan.

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 City (the city where you normally will use the watch). For more information, see “To specify your Home City” below.

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 Timekeeping Mode can be used to display the current time and date in your Home City, or the current time in your Home City (Home Time) and in one more time zone (Zone 2 Time). You can even specify a city code that supports time calibration signal reception as the Dual Time Zone 2 city code. For details about Dual Time, see “Timekeeping”.

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.

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), andANC (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 “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.

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

Time calibration signal reception takes from one to seven minutes, but in some cases it can take as long as 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 seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing 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 actually is the correct time.

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.

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.

Transmitter indicator

The watch has transmitter names along the bottom of the display. The transmitter indicator flashes during signal reception above the name of the transmitter from which the watch is currently receiving a signal. After signal reception is complete, the indicator will remain, without flashing, above the name of the transmitter from which the signal was received.

The following shows the meaning of each of the transmitter names along the bottom of the display.

JP40: Fukushima (Japan)JP60: Fukuoka/Saga (Japan)

US60: Fort Collins, Colorado (the United States)GE77.5: Mainflingen (Germany)

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.

Example: Orient the watch so its face

Solar cell

is pointing at a light source.

 

The illustration shows how to position a watch with a resin band.

Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc.

You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered even

partially.

Operation Guide 3019 3039

Important!

Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause rechargeable battery power to run down. Make sure that the watch is exposed to bright light whenever possible.

This watch uses a special rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the special rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.

Never try to remove or replace the watch’s special battery yourself. Use of the wrong type of battery can damage the watch.

The current time and all other settings return to their initial factory defaults whenever battery power drops to Level 4 and when you have the battery replaced.

Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

The LOW indicator flashes on the Timekeeping Mode Time/Date screen whenever the battery is at Level 2. You cannot change from the Time/Date screen to the dual time screen while the battery is at Level 2.

The LOW indicator at Level 2 and the flashing charge indicator (CHG) at Level 3 tell you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.

At Level 4, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 3 (indicated by the flashing charge indicator) from Level 4. You will not be able to configure any of the other settings until the battery reaches Level 1 after dropping to Level 4.

The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 4. With this Home City code setting, the watch is configured to receive the time calibration signals of Japan. If you are using the watch in North America or Europe, you will need to change the Home City code setting to match your location whenever the battery drops to Level 4.

If you use the light or alarms a number of times during a short period, the recover indicator (RECOV) appears and the following operations become disabled until battery power recovers.

Time calibration signal reception

After some time, battery power will recover and the recover indicator will disappear, indicating that the above functions are enabled again.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.

Warning!

Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

On the dashboard of a car parked in direct sunlight

Too close to an incandescent lamp

Under direct sunlight

Charging Guide

After a full charge, timekeeping remains enabled for up to about 9 months.

The following table shows the amount of time the watch needs to be exposed to light each day in order to generate enough power for normal daily operations.

You can also use the Timekeeping Mode setting screen to specify the 12/24-hourformat and to toggle power saving on and off.

All of the operations in this section are performed in the Timekeeping Mode, which you enter by pressing C.

Dual Time

The Timekeeping Mode can be used to display the current time in your Home City (Home Time) and in one more time zone (Zone 2 Time).

The minute and second setting of the Home Time and Zone 2 Time are synchronized with each other. If the time setting of either the Home Time or the Zone 2 Time is changed manually or by a signal receive operation will cause the other time setting to be changed accordingly.

You can change the time and city code setting only of the time that is currently in the Home Time position on the Dual Time screen. You cannot change the settings of Zone 2 Time position. If you want to change the time or city code setting of the Zone 2 Time, first move it to the Home Time position. After making the changes, you can move the time back to the Zone 2 Time position.

Alarm operations are performed in accordance with the time that is currently in the Home Time position on the Dual Time screen.

To switch the Dual Time screen times between the Home Time and Zone 2 Time positions

In the Timekeeping Mode, hold down Dfor about three seconds until the two times switch positions. Both of the city codes will flash for about two seconds after they switch positions.
