A WORD ON THE EXCLUSIVE NB-P4U/NB-P3U BATTERY PACKS (optional)
The NB-P4U/NB-P3U are nickel-cadmium batteries. Give
attention to the following to make the most of their
characteristics.
Terminals
Do not short-circuit
Temperature ranges:
The recharging time is based on room temperature of
20°C. The lower the temperature, the longer the recharg-
ing time.
For charging: 10°C to 35°C
For operating: -10°C to 40°C
For storing: -10°C to 30°C
CAUTION
The terminals are exposed on the bottom of the battery
pack. DO NOT short-circuit these terminals,
@ If they are shorted, a great amount of current flows.
This is not only very dangerous, but also makes the
battery pack unusable.
®@ When transporting or storing the battery pack, exercise
Special care so that no metallic object touches the
terminals.
When left attached to the recorder, the battery pack
discharges naturally, When not in use, make it a rule
to remove the battery pack.
The battery pack has been kept in the uncharged
state for shipment. Therefore, before use, charge it.
© Avoid repeated charging.
Charging the battery pack repeatedly without using it
may cause over-charging and shorten its service life.
© Recharge using only a specified charger at 10°C to
35°C,
Especially avoid recharging in a place under 10°C,
as it may cause over-charging.
© After use, store in a discharged condition.
© Do not store in places of high temperatures.
Choose a dry place with temperatures between -10°C
and 30°C for optimum storage.
@ The battery pack becomes warm immediately after
being charged. This is not due to any defect.
@ Always keep the terminals clean, !f they become dirty,
wipe them with a piece of soft cloth,
@ The fully charged NB-P4U battery pack provides power
to the HR-SIOEG/EK and a video camera (whose
power consumption is about 6 watts) for about 60
minutes of continuous recording; the NB-P3U, for
about 30 minutes.
