This watch features an electroluminescent (EL) backlight that helps you easily read the face, even in total darkness. Its Auto Light Switch function automatically lights the watch face whenever you turn your wrist towards your face. Notes

� � � �

� The backlight of the watch employs an electroluminescent (EL) light, which loses illuminating power after very long use. 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 transistor 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.
