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’s power 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 oC to 25 oC,
Recommended humidity: 40% to 60%)
≥ 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.
Prepare spare batteries when going out
for recording.
≥ Prepare batteries appropriate to 3 to 4
times the period you are planning to
record for. Cold places such as a ski resort
can shorten the period which you can
record for.
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 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.
≥ If the temperature of the battery is
extremely high or extremely low, charging
may take time or the battery may not be
charged.
≥ If you use the AC adaptor near a radio,
radio reception may be disturbed. Keep
the AC adaptor 1 m or more away from
the radio.
≥ When using the AC adaptor, it may
generate whirring sounds. However, this is
normal.
≥ After use, be sure to disconnect the AC
adaptor. (If it is left connected, a minute
amount of current is consumed.)
≥ Always keep the electrodes of the AC
adaptor and battery clean.
