First Step with HT680
Before first using the HT680, please ensure the battery is fully charged. There
are three ways to charge your HT680:
Docking Station
USB/Charging cable
Rechargeable Lithium-Ion battery pack
NOTE: Data loss may occur if the HT680's backup battery is not adequately
charged. Before charging the main battery, make sure the backup
battery switch is ON.
Install the Battery Pack
1. Remove the battery cover.
2. Move the backup battery switch to the ON position (see the description
below).
3. Insert the battery pack so that the contacts on the battery pack line up
with the contacts in the battery compartment. Fully seat the battery.
