Battery pack care
• Remove the battery pack from the video TV recorder after use, and keep it in a cool place.
When the battery pack is installed on a video TV recorder, a small amount of current flows to
the recorder even if the POWER switch is turned off. This causes overdischarge and,

charged before each use.

Charging under a temperature ranging from 10‘C to 30°C (50°F to 86°F) is recommended.

charging and discharging cycles, the battery
life will recover its original capacity.
