Operation Guide 3071 ( B )
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after
very long use.
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• The watch may emit an audible sound whenever the display is illuminated.
This is due to vibration of the EL panel used for illumination, and does not
indicate malfunction.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• The auto light switch is turned off automatically whenever battery power is
at Level 4.
• Wearing the watch on the inside of your wrist, movement of your arm, or
vibration of your arm can cause frequent activation of the auto light switch
and illumination of the display. To avoid running down the battery, turn off
the auto light switch whenever engaging in activities that might cause
frequent illumination of the display.
• Note that wearing the watch under your sleeve while the auto light switch is
turned on can cause frequent illumination of the display and can run down
the battery.
• Illumination may not turn on if the face of the
More than 15 degrees
too high
watch is more than 15 degrees above or below
parallel. Make sure that the back of your hand
is parallel to the ground.
• Illumination turns off in about one second, even
if you keep the watch pointed towards your
face.
• Static electricity or magnetic force can interfere with proper operation of the
auto light switch. If illumination does not turn on, try moving the watch back
to the starting position (parallel with the ground) and then tilt it back towards
your face 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, illumination does not turn on until about one
second after you turn the face of the watch towards you. This does not
necessarily indicate malfunction.
• You may notice a very faint clicking sound coming from the watch when it is
shaken back and forth. This sound is caused by mechanical operation of
the auto light switch, and does not indicate a problem with the watch.
Barometer and Thermometer Precautions
• The pressure sensor built into this watch measures changes in air
pressure, which you can then apply to your own weather predictions. It is
not intended for use as a precision instrument in official weather prediction
or reporting applications.
• Sudden temperature changes can affect pressure sensor readings.
• 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 all
moisture from the case. It takes approximately 20 to 30 minutes for the
case of the watch to reach the actual surrounding temperature.

Pressure Sensor and Temperature Sensor Calibration

The pressure sensor and temperature sensor built into the watch are
calibrated at the factory and normally require no further adjustment. If you
notice serious errors in the pressure readings and temperature readings
produced by the watch, you can calibrate the sensor to correct the errors.
Important!
• Incorrectly calibrating the barometric pressure sensor can result in incorrect
readings. Before performing the calibration procedure, compare the
readings produced by the watch with those of another reliable and accurate
barometer.
• Incorrectly calibrating the temperature sensor can result in incorrect
readings. Carefully read the following before doing anything.
Compare the readings produced by the watch with those of another
reliable and accurate thermometer.
If adjustment 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.
To calibrate the pressure sensor and the temperature sensor
1. Press B to enter the Barometer/
Thermometer Mode.
2. In the Barometer/Thermometer Mode, hold
down E for about two seconds until either
OFF or the reference temperature value starts
to flash. This is the setting screen.
• If you want to calibrate the barometric
pressure sensor, press D to move the
flashing to the middle display area. This is
the pressure sensor calibration screen.
• At this time, OFF or the barometric pressure
value should be flashing on the display.
3. Use A (+) and C (–) to set the calibration value in the units shown below.
0.1 ° C (0.2 ° F)
Temperature
Barometric Pressure
1 hPa (0.05 inHg)
• Pressing A and C at the same time returns to the factory calibration
(OFF).
4. Press E to return to the Barometer/Thermometer Mode screen.
To select the temperature, barometric pressure, and altitude units
1. Enter the Timekeeping Mode.
2. Hold down E until the city code starts to
flash, which indicates the setting screen.
3. Use D to select the setting screen for the unit
you want to change.
• See step 3 under "To set the time and date"
for information about how to scroll through
setting screens.
4. Press A to change the unit setting.
• Each press of A changes the selected unit setting as shown below.
