About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on whenever you position your wrist as described below. ∙ Avoid wearing the watch on the inside of your wrist. Doing so causes the

auto light switch to operate when it is not needed, which shortens battery life.

∙ Static electricity or magnetic force can interfere with proper operation of the auto light switch. If the backlight does not light, try moving the watch back to the starting position (parallel with the ground) and then tilt it back toward you again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.

∙ Under certain conditions the backlight may not light until about one second or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

Warning!

∙Never try to read your watch when mountain climbing or hiking in areas that are dark or in areas with poor footing. Doing so is dangerous and can result in serious personal injury.

∙Never try to read your watch when running where there is danger of accidents, especially in locations where there might be vehicular or pedestrian traffic. Doing so is dangerous and can result in serious personal injury.

∙Never try to read your watch when riding on a bicycle or when operating a motorcycle or any other motor vehicle. Doing so is dangerous and can result in a traffic accident and serious personal injury.

∙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		for two seconds to turn the auto
light switch on (	displayed) and off (	not displayed).

∙In order to protect against running down the battery, the auto light switch is automatically turned off approximately three hours after you turn it on. Repeat the above procedure to turn the auto light switch back on if you

want.

∙ The indictor is on the display in all modes while the auto light switch is turned on.

Backlight Precautions

∙The electro-luminescent panel loses illuminating power after very long use.

∙The illumination provided by the backlight may be hard to see when viewed under direct sunlight.

∙The watch will emit an audible sound whenever the display is illuminated. This is caused by a transformer that vibrates when the EL panel lights up. It does not indicate malfunction of the watch.

∙The backlight automatically turns off whenever an alarm sounds.

∙Turning on the backlight in the Timekeeping Mode causes animated figures to appear on the display.
