Module No. 5678
Calibrating Temperature Readings (Offset)
The watch’s temperature sensor is adjusted at the factory and normally does not require calibration. However, you can calibrate the displayed value if you notice major errors in readings.
Check to make sure that the value you use for calibration produces correct temperature readings.
Before calibrating the temperature reading, remove the watch from your wrist and leave it in the area where you plan to measure temperature for about 20 or 30 minutes to allow the case temperature to become the same as the air temperature.
Enter the Temperature Mode.
Pull out the crown.
Rotate the crown to calibrate the temperature value.
Push the crown back in to complete the setting operation.
This displays the current temperature.
Calibration unit: 0.1 °C (0.2 °F)
To return the barometric pressure setting to its initial factory default, press (A) and (C) at the same time.
If you do not perform any operation for about two minutes after pulling out the crown, crown operations will automatically become disabled. If that happens, push the crown back in and then pull it out again.
