(Notes)
• 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.
• Do not use the thermometer out of the display range. Extremely hot or cold
temperature may cause malfunction of the watch.
