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 °C to 25 °C (59 °F to 
77 °F), Recommended humidity: 40%RH 
to 60%RH)
≥ 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 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.
