Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark.
In any mode, press L to illuminate the display for about three seconds.
" The electro-luminescent panel that provides illumination loses power after very long
use.
" The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
" The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
" The backlight automatically turns off whenever an alarm sounds.
" Frequent use of the backlight shortens the battery life.
