When to Replace the Battery Pack
While you are using your camcorder, the remaining battery indicator decreases gradually as battery
power is used up.
When the remaining battery indicator reaches the lowest point, the i indicator appears and starts flashing
in the viewfinder. [b] on page 33.
When the _-X_ i ndicator in the viewfinder changes from slow flashing to rapid flashing while you are
recording, slide the POWER switch to OFF on the camcorder and replace the battery pack. Leave the tape
in the camcorder to obtain smooth transition between scenes after the battery pack is replaced.
Note on the remaining
battery indicator
The remaining battery indicator of the camcorder may indicate a different remaining capacity from that
of the battery pack with the remaining battery indicator (not supplied). The indicator of the battery pack
is more accurate.
The Battery 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.
Battery Care
• Remove the battery pack from the camcorder after using the battery pack, and keep it in a cool place.
When the battery pack is attached to the camcorder, a small amount of current flows to the camcorder
even if the POWER switch is set to OFF, which shortens battery life.
• The battery pack is always discharging even when it is not in use after charging. Therefore, you should
charge the battery right before using the camcorder.
How to Use the Switch on the Battery Pack
This switch is provided so that you can mark the charged battery. 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 (or in whichever direction you want to remind yourself). [c] on page 33.
The Life of the Battery Pack
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 camcordrer 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 50°F to 86°F (from 10°C to 30°C ). Lower temperatures
require a longer charging time.
