Notes
• The backlight of the watch employs an electroluminescent (EL) light, which
loses illuminating power after very long use.
• Frequent use of the backlight shortens the battery life.
• 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. It
does not indicate malfunction of the watch.
• The backlight automatically turns off whenever an alarm sounds.

In any mode (except for the Recall Mode), press B to illuminate the display
for about two seconds.

GENERAL GUIDE

• The auto light switch on indicator is shown on the display in all modes while
the auto light switch is on.
• In order to protect against running down the battery, the auto light switch is
automatically turned off approximately six hours after you turn it on. Repeat
the above procedure to turn the auto light switch back on if you want.
• Pressing B in any mode (except for the Recall Mode) illuminates the
display for about two seconds, regardless of the auto light switch on/off
setting.
About the auto light switch
While the auto light switch is turned on, the backlight automatically lights for
about two seconds in any mode whenever you position your wrist as described
below.
Important!
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 illuminate.
• The backlight may not illuminate if the face of the watch is more than 15
degrees off parallel as shown below. Make sure that the back of your hand
is parallel to the ground.
