Getting the Most from the Battery Pack
How to Prepare the Rechargeable Battery Pack
Have sufficient battery pack power to do 2 or
3 times as much necordirtg than you have
pfanited.
“Battery life" as indicated in the instruction
manual or catalogue of the camcorder is
measured by the continuous recording time of
the camcorder, placed at a room temperature
using a full-charged battery.
Leaving the unit In the starrdby mode will
consume power and shorten the available
battery life. To consenre power, turn the
STANDBY switch off between recordings. A
srTKwth transition between scenes cart be
made even if recording Is stopped and started
again.
While positioning the subject or selecting an
angle, by viewing through the viewfinder, and
in using autofocus, the battery is being
expertded. The battery is also being expended
when a tape is Inserted or removed.
Battery life is shorter in a cold climate
Battery efficiency is decreased and the battery
will be used up more quickly.

Notes on Charging
Before using the battery pack, charge it
sufficientlly. A brand-new battery pack is
not charged-
Recharge the battery pack only when It is
exhausted.
• If recording is completed before the mark
CXI appears In the viewfinder, it Is
recommecded that you remove the tape,
set POWER to CAMERA, slide up the
STANDBY, and leave the camcorder until
the cXi mark blinks rapidly.
• Repeated charging while some capacity
remains causes a lowering of battery
capacity. However, the original battery
capacity can be recovered if you fully
charge and discharge the battery again.
Recharge the battery pack before using.
If the battery pack is charged fully but not
used for a long time (about
1 yeaq. it
becomes discharged. Charge it again but in
this case the battery life will be shortened
than normal. After several charging and
discharging cycles, the battery life will
recover its original capacity
Keep the Tenninals Clean
If the terminals (metaf parts on the back)
are not cfaan, 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 lime 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
During charging or recording, the battery
pack heats up. This means energy has been
gerwrated and chemical change has
occurred Inside the battery pack and this Is
not dangerous.
How to care tor the battery peck
• Remove the battery pack from the
camcorder after using it, and keep it in a
cool place. When the battery pack is
attached to the camcorder, a smalt
amount of current flows to the camcorder
even If the POWER switch Is turned off.
It causes overdischarging arnl shortens
battery life.
• The battery pack is always discharging
even when It is not In use after charging.
Thus it is recommernfed you charge the
battery before using.
How to use the switch on the battery pack
This switch is provided so that you can
remember the charging condition. 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
It can be fully charged and discharged about
500 times under normal temperatures. If the
cX! mark blinks rapidly just after turnlr>g on
the camcorder with a fully charged battery
pack, .the battery pack should be replaced
with a new fully charged one.
Temperatures during charging
Lower temperatures require a longer charging
time. Charging under temperatures ranging
from 10®C to 30°C is recommefKled.
