Switch On Backup Battery

Locate the backup battery switch inside the battery
compartment on the left-hand side. Please ensure that
it is in the "ON" position before charging the main
battery.

Supply Power to the HT680

Connect the USB/Charging Cable to the HT680 and connect the AC adapter to
the cable's power jack and an electrical outlet.
Or place the HT680 into the Docking Station (first connect the power supply to
the Docking Station).
First Time Charging the Main & Backup Battery
Unitech recommends charging the battery at least up to 16 hours for the first
time to use. While it normally only takes about 4 hours to charge the battery
after it's been drained, when charging the battery for the first time please allow
at least 16 hours. While charging the main battery the backup battery should
also be charged. It is imperative the backup battery has been switched "ON".
