Important!

• Never press the touch screen with a sharp object, which can damage the

• The touch screen is installed on top of the glass. This type of construction
may produce a rainbow effect on the display. The appearance of such
phenomenon does not indicate any problem and there is no need for
concern.

• You may experience problems with touch screen operation if the watch is
left for a long time in an area subjected to temperatures above 60°C
(140°F).

• This watch is not water resistant, so avoid high humidity and direct contact
with water. Also, do not wear the watch during activities that may cause
you to sweat a lot.

• The touch screen becomes convex at high temperatures and high altitudes.
This watch can still be used normally, and the screen will become flat again
when the temperature or altitude return to normal.

BACKLIGHT

Auto light switch on

Turning on the backlight manually

In any mode, press to illuminate the display for about two seconds.

• The above operation turns on the backlight regardless of the current auto
light switch setting.

• The backlight remains lit for about two seconds from the point you press

, even if it is already lit when you press . If you keep depressed for

five seconds, the backlight will automatically turn off.

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.

• 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.

The backlight uses an EL (electro-luminescent)
panel that causes 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.

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.

Parallel to
ground

• The backlight turns off in about two seconds, even if you keep the watch
pointed towards your face.

• The backlight may not light if the face of the watch is more than 15 degrees
off the parallel as shown below. Make sure that the back of your hand is
parallel to the ground.

Parallel to ground

• Static electricity or magnetic force can interfere with proper operation of
the auto light switch. If the backlight does not light, 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.

• Under certain conditions the backlight may not light until about one second
or less after turn the face of the watch towards you. This does not
necessarily indicate malfunction of the backlight.

accidents, especially in locations where there might be vehicular or
pedestrian traffic. Doing so is dangerous and can result in serious

Backlight Precautions

• 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.

It does not indicate malfunction of the watch.

• The backlight automatically turns off whenever an alarm sounds.

• Turning on the backlight in the Timekeeping Mode causes animated

figures to appear on the display.
