Panasonic NV-GS250GN Operating Instructions Manual page 58

Do not use this movie camera for surveillance
purposes or other business use.
≥If you use the movie camera for a long time, the
internal temperature increases and,
consequently, this may cause malfunction.
≥This movie camera is not intended for business
use.
About the flash
≥Since there are high-voltage sections inside the
flash, do not disassemble it to avoid electric
shock.
ª About the battery
The battery used in the movie camera is a
rechargeable lithium ion battery. This battery is
susceptible to temperature and humidity, and the
effect of temperature increases with increasing or
decreasing temperature. In the low temperature
range, the fully charged indication may not
appear, or the low battery indication may appear
about 5 minutes after the start of use. At high
temperature, moreover, the protection function
may work, disabling use of the movie camera.
Be sure to detach the battery after use
≥If the battery is left attached to the movie
camera, a minute amount of current is
consumed even when the movie camera power
is [OFF]. If the battery is left attached to the
movie camera for a long time, over-discharge
takes place. The battery may become unusable
after it is charged.
Prepare spare batteries when going out for
recording.
≥Prepare batteries appropriate to 3 to 4 times the
period during you want to record pictures in. In
cold places such as a ski resort, the period
during which you can record pictures is
shortened.
≥When you travel, do not forget to bring an AC
adaptor so that you can recharge the batteries
at your destination.
If you drop the battery accidentally, check to
see if the terminals are deformed.
≥Attaching a deformed battery to the movie
camera or AC adaptor may damage the movie
camera or AC adaptor.
After use, be sure to take the cassette out and
detach the battery from the movie camera or
pull out the AC mains lead from AC mains
socket.
≥The battery should be stored in a cool place free
from humidity, with as constant temperature as
possible. (Recommended temperature: 15oC to
25oC, Recommended humidity: 40% to 60%)
≥Extremely high temperatures or low
temperatures will shorten the life of the battery.

≥If the battery is kept in a high-temperature, high-
humidity, or oily-smoky places, the terminals
may rust and cause malfunctions.
≥To store the battery for a long period of time, we
recommend you charge it once every year and
store it again after you have completely used up
the charged capacity.
≥Dust and other matter attached to the battery
terminals should be removed.
Do not throw old battery into fire.
≥Heating a battery or throwing it into a fire may
result in an explosion.
≥If the operating time is very short even after the
battery has been recharged, the battery has
worn out. Please purchase a new battery.
ª
About the AC adaptor
≥If the battery is warm, charging requires more
time than normal.
≥If the temperature of the battery is extremely
high or extremely low, the [CHARGE] lamp may
continue flashing, and the battery may not be
charged. After the battery temperature has
decreased or increased sufficiently, recharging
starts automatically. So, wait for a while. If the
lamp still continues flashing even after the
recharging, the battery or AC adaptor may be
faulty. If so, please contact a dealer.
≥If you use the AC adaptor near a radio, radio
reception may be disturbed. Keep the AC
adaptor 1 metre or more away from radio.
≥When using the AC adaptor, it may generate
whirring sounds. However, this is normal.
≥After use, be sure to pull out the AC mains lead
from the AC mains socket. (If they are left
connected, a minute amount of current is
consumed.)
≥Always keep the electrodes of the AC adaptor
and battery clean.
ª
About the cassette
Never place the cassette in a high temperature
place.
≥The tape may be damaged, producing
mosaic-like noise at the time of playback.
When storing the cassette after use, be sure
to rewind the tape to the beginning and take it
out.
≥If the cassette is left for more than 6 months
(depending on the storage condition) in the
movie camera or stopped midway, the tape may
sag and be damaged.
≥Once every 6 months, wind the tape to the end
and then rewind it to the beginning. If the
cassette is left for 1 year or longer without
winding or rewinding, the tape may be deformed
by expansion or shrinkage attributable to
temperature and humidity. The wound tape may
stick to itself.
