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 turn on the backlight under bright light.

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

•Wear the watch on the outside of your wrist.

Warning!

•Always make sure you are in a safe place whenever you are reading the display of 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 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.

Power Supply

This watch is equipped with a solar cell and a rechargeable 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 is	Solar cell
pointing at a light source.

•The illustration shows how to position awatch 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 only partially.

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. Be sure that the watch is exposed to bright light whenever

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

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.

Exposure Level (Brightness)	Approximate
	Exposure Time
Outdoor Sunlight (50,000 lux)	5 minutes
Sunlight Through a Window (10,000 lux)	24 minutes
Daylight Through a Window on a Cloudy Day (5,000 lux)	48 minutes
Indoor Fluorescent Lighting (500 lux)	8 hours

•For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications.

•Stable operation is promoted by frequent exposure to light.

Recovery Times

The table below shows the amount exposure that is required to take the battery from one level to the next.

times depend on lighting conditions.

possible.

• This watch uses a 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 rechargeable battery to charge fully, contact your dealer or

CASIO distributor about having it replaced.

• Never try to remove or replace the watch’s rechargeable battery yourself. Use of the

wrong type of battery can damage the watch.

• All data stored in memory is deleted, and 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.

•The flashing LOW indicator at Level 3 tells 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. Once the battery reaches Level 2 after falling to Level 5, reconfigure the current time, date, and other settings.

•The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5. 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, or China you will need to change the Home City code setting to match your location whenever the battery drops to Level 5.

•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.

•Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.
