Changing the battery: The battery is designed to be quickly
changed (if you have additional batteries). The unit saves enough
power that if you swap the battery within approximately one
minute, it will not trigger a reset. If the saved power runs out
before the new battery is installed, the unit will reset. This will not
impact saved data, programs or configuration, however unsaved
data will be lost and the time will need to be reset.
To change a battery, perform the following steps:
1. Close open applications and save data in case the battery
exchange takes too long.
2. Remove the hand strap from the unit.
3. Turn the unit off using
