ABOUT THE BACKLIGHT

The EL backlight of this watch is designed to start working on December 25, 1999. The backlight will not work until this date, even if you try to set the date setting ahead to December 25. All the backlight operations described in this User’s Guide can be performed after December 25, 1999.

direct sunlight.

• The backlight automatically turns off whenever an alarm sounds.

About the Auto Light Switch Function

When the auto light switch function is turned on, the backlight automatically turns on for two seconds under the conditions described below. Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when not needed, which shortens battery life.

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

More than 15 degrees too low

Moving the watch to a position that is parallel to the ground and then tilting it towards you approximately 40 degrees causes the backlight to illuminate.

• Static electricity or magnetic force can interfere with proper operation of the auto backlight function. If the auto 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.
