BACKLIGHT
The backlight uses an EL (electro-luminescent)
panel that cause the entire display to glow for
easy reading in the dark. The watch’s auto light
switch automatically turns on the backlight when
you angle the watch towards your face.
• The auto light switch must be turned on
(indicated by the auto light switch on indicator)
for it to operate.
Note
• The electro-luminescent panel loses
illuminating power after very long use.
• The illumination provided by the backlight may be hard to see when viewed
under direct sunlight.
• The watch will emit an audible sound whenever the display is illuminated.
This is caused by vibration of the EL panel when it is lit. It does not indicate
malfunction of the watch.
• The backlight automatically turns off whenever an alarm sounds.

To manually turn on the backlight
Depending on the mode, pressing L or D turns on the backlight for about two
seconds. See the sections that cover each mode for information on whether
you should press L or D.
• The backlight remains lit for about two seconds from the point you press the
button, even if it is already lit when you press the button. If you keep the
button depressed for five seconds or more, the backlight automatically turns
off.
• The above operation turns on the backlight regardless of the current auto
light switch setting.
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on whenever you
position your wrist as described below. Note that the auto light switch of this
watch will operate only when available light is below a certain level. It does not
turn on the backlight under bright light.
• Avoid wearing the watch on the inside of your wrist. Doing so causes the
auto light switch to operate when it is not needed, which shortens battery life.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes the backlight to light.
