Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to carefully read this manual and keep it on hand for later reference when necessary.

Expose the watch to bright light to charge its battery before using it.

You can use this watch even as its battery is being charged by exposure to bright light.

• Be sure to read “Battery” of this manual for important information you need to know when exposing the watch to bright light.

If the display of the watch is blank...

If the SLEEP indicator is on the display, it means that the display is blank because the watch’s Power Saving function has turned off the display to conserve power. Power Saving automatically turns off the display and puts the watch into a sleep state whenever your watch is left for a certain period where it is dark.

• The initial factory default setting is Power Saving on.

• The watch recovers from the sleep state if you move it to

a well-lit area*, if you press any button, or if you angle the watch towards your face for reading.

It can take up to five seconds for the display to turn on.

Backlight

Auto light switch on indicator

causes the entire display to glow for easy reading in the dark. The watch’s auto light switch automatically turns on the backlight when you angle the watch towards your face.

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

• See “Backlight Precautions” for other important information about using the backlight.

To turn on the backlight manually

In any mode, press B to illuminate the display for about one second.

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

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on for about one second, whenever you position your wrist as described below in any mode.

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

Parallel to ground

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 surprise 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 the Timekeeping Mode, hold down D for about two seconds to toggle the auto light switch on (AUTO EL displayed) and off (AUTO E L not displayed).

• The auto light switch on indicator (AUTO EL ) is on the display in all modes while the auto light switch is turned on.

Battery

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

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

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

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 normally exposed to bright light whenever possible.

• This watch employs a solar cell that converts light into electricity, which charges a built-in rechargeable battery. Normally, the rechargeable battery should not need replacement, but after very long use over a number of years, the rechargeable battery may lose its ability to achieve a full charge. Should you notice problems with getting the rechargeable battery to a full charge, contact your dealer or CASIO distributor about having the rechargeable battery replaced.

• The rechargeable battery should be replaced with a CASIO-specified CTL1616 battery only. Other rechargeable batteries can cause damage to 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.

Battery Power Indicator

The battery power indicator on the display shows you the current status of the rechargeable battery’s power.

Battery power indicator

• The flashing indicator at Level 4 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. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time, date, and all other settings after the battery is recharged to Level 3 from Level 5. Though the time appears on the display after the battery is charged to Level 4, you will not be able to change the time setting until the battery reaches Level 3.

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

• If you use the backlight or any of the alarm functions a number of times during a short period, RECOVER appears on the display and the following operations become disabled until battery power recovers.

Backlight Beeper tone

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