About The Ac Adaptor - Panasonic HDC-SD40 Owner's Manual

≥ Extremely high temperatures or low
temperatures will shorten the life of the
battery.
≥ If the battery is kept in 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.
Bring spare batteries when going out for
recording.
≥ Prepare batteries enough to last for 3 to 4
times the period you are planning to
record for. Cold places such as a ski resort
can shorten recording time.
If you drop the battery accidentally,
check to see if the terminals are
damaged.
≥ Inserting a battery with damaged terminals
can damage the unit.
Do not throw an 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.
