ABOUT THE BACKLIGHT

Pressing 

L

 illuminates the display for about two seconds. If you hold down 

L

, the light

automatically disappears after five seconds.

TELEMEMO MODE

The backlight of this watch employs an electro-
luminescent (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 indi-
cate malfunction of the watch.

Frequent use of the backlight shortens the battery
life.
