Warning! Be sure to only use the power supply included with your
unit. Use of other adapters may void the product warranty.
Changing the battery: The unit was designed to be able to change
the battery quickly without resetting it. The unit saves enough
power (in Replace Battery mode) that if you swap the battery within
approximately one minute, it will not trigger a reset.
WARNING: 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 settings 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. Enter the
Replace Battery
mode (ensures that alarms will not
wake up the unit while changing the battery). Press and hold
the
Power
key and tap
Replace Battery
. See page 16.
4. Use the supplied stylus or a small #1 Philips head screwdriver
to loosen the four screws in the battery door.
5. Remove the battery from the unit.
6. Quickly insert the replacement
battery onto the unit.
7. Place the battery door over the
battery, with the flat side of the
battery door at the top of the unit.
Use the stylus or screwdriver to finger-tighten the four screws.
8. Replace the hand strap.
9. Turn on the unit to resume operation.
Calibrating the battery: The battery has an internal gauge that
provides an estimate of the amount of energy in the battery as it
charges and discharges. If your battery is showing inaccuracy in the
power gauge or large jumps in capacity, (i.e. the power is reading
50% and goes dead shortly thereafter) it may need calibration.
Tap Start / Settings / System / Power / Calibration to see if the
message reads Calibration recommended or Calibration not
necessary. If calibration is recommended or the battery is reporting
inaccurately, perform the following:
