Tips for using the battery pack
Notes on the rechargeable battery pack
Caution
Never leave the battery pack in temperatures above 60°C (140°F), such as in a car
parked in the sun or under direct sunlight.
The battery pack heats up
During charging or recording, the battery pack heats up. This is caused by energy that
has been generated and a chemical change that has occurred inside the battery pack.
This is not cause for concern and is normal.
Be sure to observe the following
•Keep the battery pack away from fire.
•Keep the battery pack dry.
•Do not open nor try to disassemble the battery pack.
•Do not expose the battery pack to any mechanical shock.
The life of the battery pack
If the battery indicator flashes rapidly just after turning on the camcorder with a fully
charged battery pack, the battery pack should be replaced with a new fully charged one.
Charging temperature
You should charge batteries at temperatures from 10°C to 30°C (from 50°F to 86°F).
Lower temperatures require a longer charging time.
