About the Backlight
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.
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.

Caution
The backlight of this watch employs an electro-luminescent (EL) light, which loses itsx
illuminating power after very long term use.
Frequent use of the backlight shortens the battery life.x
The watch emits an audible sound whenever the display is illuminated. This isx
because the EL light vibrates slightly when lit. It does not indicate malfunction of
the watch.

after turning the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.

Static electricity or magnetic force can interfere with proper operation of the autox
backlight function. If the auto backlight does not illuminate, try moving the watch

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.
