• Frequent use of the backlight shortens the battery life.

• 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.

To manually turn on the backlight

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

To turn the Auto Light Switch function on and off

In the Timekeeping Mode, hold down C for one or two seconds to turn the Auto Light Switch function on and off.

• The Auto Light Switch on indicator is shown on the display in all modes while the Auto Light Switch function is on.

• In order to protect against running down the battery, the Auto Light Switch function is automatically turned off approximately two hours after you turn it on. Repeat the above procedure to turn the Auto Light Switch function back on if you want.

• Pressing L in any mode illuminates the display for about one second, regardless of the Auto Light Switch function on/off setting.

About the Auto Light Switch function

While the Auto Light Switch function is turned on, the backlight automatically lights for about one second in any mode whenever you position your wrist as described below.

Important!

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.

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 illuminate.

Parallel to ground

• The backlight may not illuminate if the face of the watch is more than 15 degrees off parallel as shown below. Make sure that the back of your hand is parallel to the ground.

Parallel to ground

• Static electricity or magnetic force can interfere with proper operation of the Auto Light Switch function. If the backlight does not illuminate, 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 on a roadside or in any other location 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 function 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 function can create a distraction, which can result in a traffic accident and serious personal injury.
