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.
Parallel to ground More than 15 degrees
too high More than 15 degrees
too low
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.

•Compare the readings produced by the watch with those of another reliable,
accurate thermometer.
•If calibration is required, remove the watch from your wrist and wait for 20 or 30
minutes to give the temperature of the watch time to stabilize.
•Perform the temperature calibration before procedure as quickly as possible to avoid
