Tips for using the battery pack
Why the remaining battery indication does not match the
continuous recording time in the operating instruction
The recording time is affected by the environmental temperature and conditions. The
recording time becomes very short in a cold environment. The continuous recording time in
the operating instruction is measured under the condition of using a fully charged (or
normal charged
2) ) battery pack in 77
°
F (25
°
C). As the environmental temperature and
condition are different when you actually use the camcorder, the remaining battery time is
not same as the continuous recording time in the operating instruction.
1) Full charge: Charging for about 1 hour after the charge lamp of the AC power adaptor goes
off.
2) Normal charge: Charging just until the charge lamp of the AC power adaptor goes off.
Notes on charging
A brand-new battery pack
A brand-new battery pack is not charged. Before using the battery pack, charge it
completely.
Recharge the battery pack whenever you like
You do not have to discharge it before recharging. If you charged the battery pack fully but
you did not use it for a long time, it becomes discharged. Then recharge the battery pack
before use.
Notes on the terminals
If the terminals (metal parts on the back) are not clean, the battery charge
duration will be shortened
When the terminals are not clean or when the battery pack has not been used for a long time,
repeatedly install and remove the battery pack a few times. This improves the contact
condition. Also, wipe the +, – and C terminals with a soft cloth or paper.
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.
