Note: Verify that the battery is installed prior to connecting the wall
charger. If both the wall charger is connected and the battery is
not installed, the handset will power cycle continuously and
prevent proper operation. Failure to unplug the wall charger
before you remove the battery, can cause the device to become
damaged.
