1.6 Battery Storage and Safety Precautions
Batteries should be stored at normal room temperature. Avoid placing them in any situation where
explosion or damage could possibly occur. The Li-Ion batteries may lose their charge if not used for
several months due to back up and internal resistance. If this happens, we suggest recharging prior to
use.
Remove Main Battery
To remove the main battery, press down on the release button while pushing out the cover on the unit.
We suggest that the battery not be removed, if possible.
Charging
When starting to operate the HT580, the main battery must be fully charged before the first use. The
HT580 is equipped with a 3.7V 600m.A.h Lithium-Ion battery. It takes 8 hours to fully charge the main
battery when empty. We suggest users recharge the battery regularly after long hours of use.
This icon shown in the menu is to indicate the current battery capacity status.
There are 2 ways to charge the main battery:
1. Mount the unit in the cradle and connect power adaptor between the back of the cradle and any
power outlet.
2. Or, use the standard USB cable and connect it to your PC’s USB port.
