ABOUT THE BACKLIGHT
About the Auto Backlight Function
When the auto backlight function is turned on, the backlight automatically turns on for
two seconds under the conditions described below. Avoid wearing the watch on the
inside of your wrist. Doing so causes the auto backlight to operate when not needed,
which shortens battery life.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you approximately 40 degrees causes the backlight to illuminate.
Parallel to
ground
• 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.
• 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.
• 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.

To switch the auto backlight function on and off
In the Timekeeping Mode, hold down for one or two seconds to turn the auto
backlight function on and off.
• The auto backlight indicator is shown on the display in all modes while the auto
backlight function is on.
• 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 at any time illuminates the display for about two seconds, regardless of
the auto backlight's on/off setting.

Caution
• The backlight of this watch employs an electro-luminescent (EL) light, which loses its
illuminating power after very long term use.
• Frequent use of the backligfht shortens the battery life.
• The watch emits an audible sound whenever the display is illuminated. This is because the
EL light vibrates slightly when lit. It does not indicate malfunction of the watch.
Warning!
• Never try to read your watch when mountain climbing or hiking in areas that are dark
or in areas with poor footing. Doing so is dangerous and can result in serious
personal injury.
• Never try to read your watch when running on a roadside or in any other location
where there might be vehicular or pedestrian traffic. Doing so is dangerous and can
result in serious personal injury.
• Never try to read your watch when riding on a bicycle or when operating a motorcycle
or any other motor vehicle. Doing so is dangerous and can result in a traffic accident
and serious personal injury.
• When you are wearing the watch, make sure that its auto backlight function is turned
off before riding on a bicycle or operating a motorcycle or any other motor vehicle.
Sudden and unintended operation of the auto backlight can create a distraction,
which can result in a traffic accident and serious personal injury.
THERMOMETER MODE
A built-in temperature sensor measures temperature and shows the measured value
on the display. The readout from the temperature sensor can also be switched
between Celsius (˚C) and Fahrenheit (˚F). The thermometer can be calibrated to
correct for errors.
Important!
Temperature measurements are affected by your body temperature (while you are
wearing the watch), direct sunlight, and moisture. To achieve a more accurate
temperature measurement, remove the watch from your wrist, place it in a well
ventilated location out of direct sunlight, and wipe off all moisture from the case. It
takes approximately 20 to 30 minutes for the case of the watch to reach the actual
surrounding temperature.
Accurate temperature measurements cannot be achieved while you are wearing the
watch. The following graph illustrated affects of body temperature on actual
temperature.

About Temperature Measurement
• A temperature graph which is automatically updated every five minutes, is shown on
the display in all modes (except when making settings). Measured temperature
values can be viewed in the Thermometer Mode only.
• Pressing while in the Thermometer Mode
performs temperature measurement and causes
the measured value to appear on the display.
The display shows “– – . – ˚C (or ˚F)” if a
measured value falls outside the range of –20˚C
to 60˚C (–4˚F to 140˚F). The normal display will
return as soon as the temperature returns within
the allowable range.
