to enter the
Thermometer Mode and start a temperature reading
operation.

2. To stop the temperature reading operation, press
D
to return to the Timekeeping
Mode.
• The watch will stop taking temperature readings and return to the Timekeeping
Mode automatically if you do not perform any operation for about one or two hours.
Temperature
• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to
- - -
°C (or °F) if a measured
temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The
temperature value will reappear as soon as the measured temperature is within the
allowable range.
Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature
value. See “To specify the temperature unit” (page E-21) for more information.

Temperature Sensor Calibration
The watch’s temperature sensor is calibrated at the factory and normally requires no
further adjustment. If you notice serious errors in the temperature readings produced
by the watch, you can calibrate the sensor to correct the errors.
Important!
• 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.
E-19
To calibrate the temperature sensor
1. Enter the Thermometer Mode, which will start a
temperature reading operation and display the results
(page E-16).
2. Hold down
A
for about two seconds.
• Holding down
A
will initially cause Hold to appear
on the screen. Keep
A
depressed until Hold
disappears.
• This will cause the temperature reading operation to
re-start, and display the sensor calibration screen
shown in the illustration nearby.
3. Use
D
(+) and
B
(–) to change the displayed calibration by 0.1°C (0.2°F) steps.
• To return the currently fl ashing value to its initial factory default setting, press
D
and
B
at the same time. OFF will appear in place of the fl ashing temperature
