TOUCH SCREEN PRECAUTIONS
The touch screen of this watch shows a button menu that lets you select the
function you want by simply pressing the correct on-screen button with your
finger.
• The button menu shows only the functions that are currently available in
the mode you are in. Buttons for unavailable functions are not displayed.
• Take care that you touch the part of the touch screen that contains the
button whose function you want to perform.
• The following illustrations show the correct way to press an on-screen
button.
Important!
• Never press the touch screen with a sharp object, which can damage the
screen. Use your finger only.
• 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
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.
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.
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.
• 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.
• 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.
