Data Recall, Alarm, Receive, Digital Compass, or Barometer/Thermometer Mode. • If you do not perform any button operation while in the Altimeter Mode, the watch returns to the Timekeeping Mode automatically after nine or 10 hours (altitude measurement type: 2’00) or after one hour (altitude measurement type: 0’05).
To recover from the sleep state Perform any one of the following operations. • Move the watch to a well-lit area. It can take up to two seconds for the display to turn on. • Press any button.
