are three ways to charge your HT680:

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 door.
2. Move the backup battery switch to the ON position (see the description

compartment on the left-hand side. Please ensure that
it is in the “ON” position before charging the main
battery.
