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.

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

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.

Fort Collins (United States) transmitter: 600 miles (1,000 kilometers) Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)

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 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. The reception schedule (calibration times) depends on your currently selected Home City, and whether standard time or Daylight Saving Time is selected for your Home City.

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 five minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing any button operation within five 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.

(Level 3)

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: Rugby (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.

The flashes on the display in the Timekeeping Mode when battery is at Level 3.
The at Level 3 and the flashing charge indicator (CHG) at Level 4 tell you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.
At Level 5, 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 4 (indicated by the flashing charge indicator (CHG)) from Level 5. You will not be able to configure any of the other settings until the battery reaches Level 3 (no charge indicator) after dropping to Level 5.
Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to show a reading that is momentarily higher than the actual battery level. The correct battery power indicator should appear after a few minutes.
If you use the illumination or alarms a number of times during a short period, the charge indicator (CHG) flashes and the following operations become disabled until battery power recovers.

Time calibration signal reception
After some time, battery power will recover and the charge indicator (CHG) 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

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 5 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.

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 only partially covered.

Illumination

Module 3050 (A)

Auto light switch indicator

Module 3061

The watch has an EL (electro-luminescent)panel that causes the entire display to glow for easy reading in the dark. The watch’s auto light switch illuminates the display automatically when you angle the watch towards your face.

The auto light switch must be turned on (indicated by the auto light switch indicator) for it to operate.

See “Illumination Precautions” for other important information.

To turn on illumination manually

In any mode press L to illuminate the display.

The above operation turns on illumination regardless of the current auto light switch setting.

About the Auto Light Switch

Turning on the auto light switch causes illumination to turn on whenever you position your wrist as described below in any mode. Note that this watch features a “Full Auto EL Light,” so the auto light switch operates only when available light is below a certain level. It does not illuminate the display under bright light.

Moving the watch to a position that is parallel to the ground and then tilting it towards you at more than 40 degrees causes illumination to turn on.

Wear the watch on the outside of your wrist.

40°

Warning!

Always make sure you are in a safe place whenever you are reading the watch using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding on a bicycle, or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury.

To turn the auto light switch on and off

In Timekeeping mode (except when a setting screen is on the display), hold down L for about three seconds to toggle the auto light switch on (auto light switch indicator displayed) and off (auto light switch indicator not displayed).

The auto light switch indicator remains in all modes while the auto light switch is turned on.
