The battery used in this unit is a rechargeable lithium-ion battery. It is
susceptible to humidity and temperature and the effect increases the
more the temperature rises or falls. In cold areas, the full charge
indication may not appear or the low battery indication may appear about
5 minutes after starting use. At high temperatures, the protection function
may be triggered, making it impossible to use the unit.
Be sure to detach the battery after use.
≥
If the battery is left attached, a minute amount of current continues to
flow even if the unit is off. Keeping the unit in this state may result in
over discharge of the battery. This may result in you not being able to
use the battery even after it is charged.
≥
The battery should be stored in the vinyl bag so metal does not come
into contact with the terminals.
≥
The battery should be stored in a cool place free from humidity, with as
constant temperature as possible. (Recommended temperature: 15
o
C
to 25
o
C, Recommended humidity: 40%RH to 60%RH)
≥
Extremely high temperatures or low temperatures will shorten the life
of the battery.
≥
Do not contaminate the terminal portion of the battery attachment
portion or the battery terminals.
≥
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.
≥
Do not remove the external labels and this may result in a malfunction
of the unit.
Prepare 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.
