ABOUT THE BACKLIGHT

GENERAL GUIDE

Pressing L illuminates the display for about two seconds. If you hold down L, the light automatically disappears after five seconds.

• The backlight of this watch employs an electroluminescent (EL) light, which loses its illuminating power after very long term use.

• The watch emits an audible sound whenever the display is illuminated. This is caused because the EL light vibrates slightly when lit. It does not indicate malfunction of the watch.

• Frequent use of the backlight shortens the battery life.
