BACKLIGHT
This watch features an electroluminescent
(EL) backlight that helps you easily read the
face, even in total darkness. Its Auto
Backlight function automatically lights the
watch face whenever you turn your wrist
towards your face.
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.
This is caused by a transistor that vibrates when the EL panel lights up. It
does not indicate malfunction of the watch.
• The backlight automatically turns off whenever an alarm sounds.
To manually turn on the backlight
In any mode, press E to illuminate the display for about two seconds.
To switch the auto backlight function on and off
In the Timekeeping Mode, hold down D for one or two seconds to turn the
auto backlight function on and off.

• In order to protect against running down the battery, the auto backlight
function is automatically turned off approximately three hours after you
turn it on. Repeat the above procedure to turn the auto backlight function
back on if you want.
• Pressing E in any mode illuminates the display for about two seconds,
regardless of the auto backlight function on/off setting.
About the Auto Backlight function
While the Auto Backlight function 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 Backlight 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 to the left or right. Make sure that the back of your
hand is parallel to the ground.
• The auto backlight indicator is shown on the display in all modes while
the auto backlight function is on.
• Static electricity or magnetic force can interfere with proper operation of
the auto backlight function. If the auto backlight does not illuminate, try
moving the watch back to the starting position (parallel with the ground)
and then tilt it back toward you 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.
GENERAL GUIDE
• Press C to change from mode to mode. Hold down C for one or two
seconds in any mode to switch back to the Timekeeping Mode.
• In addition to the modes illustrated below, this watch is also equipped
with a Digital Compass Mode. See “Digital Compass Functions” for
