Recharge the battery pack after long storage.
If the battery pack is charged fully but not used for a long time (about 1 year), it becomes discharged.
Charge it again but in this case the battery duration will be shorter than normal. After several charging and
discharging cycles, the battery will recover its original capacity.
Keep the Terminals Clean [f]
If the terminals (metal parts on the back) are not clean, the battery duration will be shortened,
When the terminals are not clean or when the battery pack has not been used for a long time, install and
remove the battery pack from time to time. This will improve the contact condition. Also, wipe the + and -
terminals with a soft cloth or paper.
Notes on the Rechargeable Battery Pack
Why the battery pack heats up? [g]
During charging or recording, the battery pack heats up. This means energy has been generated and
chemical change has occurred inside the battery pack, and this is not dangerous.
How to care for the battery pack
• Detach the battery pack from the camcorder after using it, and keep it in a cool place. When the battery pack
is on the camcorder, a small amount of current flows to the camcorder even when it is turned off, This
gradual discharge shortens battery life,
• The battery pack is always discharging even when it is not in use after charging. Thus, it is recommended
that you charge the battery right before using.
How to use the switch on the battery pack [h]
This switch is provided so that you can remember the charging status. Set the switch to the "no mark" position
when charging is completed. Set the switch to the "red mark" position when the battery is used up.

How many times can the battery pack be recharged?
The battery pack can be fully charged and discharged about 500 times under normal temperatures. If the __\_
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,
Recommended temperatures during charging
The temperature range of charging is 5°C to 35°C (41°F to 95°F). However, to provide maximum battery
efficiency, the recommended temperature range when charging is 10°C to 30°C (50°F to 86°F).
Be sure to observe the followings:
• To prevent an accident caused by a short circuit, do not allow metal objects such as a necklace to
touch the battery terminals. Carry the battery pack attaching to the terminal cover.
• Keep the battery pack away from fire.
• Keep the battery pack dry,
• Do not open nor convert the battery pack.
• Do not expose the battery pack to any mechanical shock,
