Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See “To specify
the temperature unit” (page E-25).
Temperature Sensor Calibration
The temperature sensor built into the watch 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.
