Cautions concerning the rechargeable batteries
Read the following descriptions carefully
when you use the lithium ion battery (LI-
50B).
Discharging:
The rechargeable batteries self-discharge
while this is not in use. Be sure to charge
them regularly before use.
O
p
erating temperature:
The rechargeable batteries are chemical
products. The rechargeable batteries
efficiency may fluctuate even when
operating within the recommended
temperature range. This is an inherent
nature of such products.

commended temperature range:
When operating appliance:
0°C - 42°C/ 32°F - 107.6°F
Charging:
5°
C - 35°C/ 41°F - 95°F
Storage for a long period:
–20°C - 30°C/ –4°F - 86°F
Power supply
Using the rechargeable battery outside
the above temperature range may result in
declining efficiency and shorter battery life.
In order to prevent battery leakage or rust,
remove the rechargeable battery from the
products when you will not be using them
for a long time, and store them separately.
Battery indicator
The battery indicator on the display changes
as the battery loses power.

Notes
• This recorder is designed to fully charge

atteries regardless of their energy level.
However, for best results when charging
newly purchased rechargeable batteries
or batteries that have not been used
for a long time (more than one month),
it is recommended to fully charge the
batteries then discharge repeatedly for 2
to 3 times.

W
hen disposing rechargeable batteries,
always observe the local laws and
regulations. Contact your local recycling
center for proper disposal methods.
