22.3. Battery Replacement
The internal Lithium-Ion battery does not require any special maintenance. If the
battery is no longer holding a charge, it may need to be replaced. Under normal
conditions of use, the battery lifetime is around three years.
The procedure for replacing the battery is as follows:
1. Power down the device.
2. Remove the battery access door on the bottom of the device.
3. Remove the old battery by pulling on the strap that is attached to the battery.
4. Insert the new battery, taking care to face the label-side of the battery towards the
front of the device. (The battery will not fully insert, otherwise.)
5. Reattach the battery access door.
WARNING – APPROVED BATTERIES. Only use batteries that are
