5. USING THE THERMOMETER
The thermometer indicates the current or last measured temperature in all
modes except the chronograph mode.
Temperature is measured in two ways:
1. By button operation at any time
2. Automatically measured every hour, on the hour
Temperature can be indicated either in centigrade (°C) or on Fahrenheit (°F).
<Automatic temperature measurement>
Temperature is automatically measured every hour, on the hour and when the
mode changes from chronograph to race timer.
However, if the watch is in the setting status (blinking indication) in time mode or
chronograph mode at the moment of measurement, no temperature is
measured.
<Temperature measurement by button operation>
If button
B
is pressed in the normal time mode or calendar mode, temperature
is repeatedly measured for 3 minutes at intervals of 2 seconds.

<Temperature measurement range and accuracy>
(Note)
• If the watch is worn on the wrist durning temperature measurement, the body
temperature affects measurement.
For accurate temperature measurement, take the watch off and leave it in the
measuring environment at least for 20 to 30 minutes. The influence of body
temperature depends on environmental conditions such as difference between
atmospheric temperature and body temperature before taking the watch off,
etc.
