Olympus DS-2500 - Manual (Page 16)

Notes
• Insert the supplied rechargeable battery and
set [Battery] to [Ni-MH]. If [Battery] is set to
[Alkaline], you cannot recharge (
☞ P.13).
• You cannot charge when [
ø]*1 or [√]*2
blinks. Charge the batteries at a temperature in
the range of 5°C to 35°C (41°F to 95°F).
*1 [
ø]: When the surrounding temperature is low.
*2 [
√]: When the surrounding temperature is
high.
• When using time becomes notably short even
after the batteries are fully charged, replace them
with new ones.
• Be sure to push the USB connector all the way in.
Otherwise, the recorder may not operate properly.
• Be sure to use the included dedicated USB cable.
If any other company’s cable is used, it may lead
to malfunction of the recorder. Also, never use
this dedicated cable with any other company’s
products.
• If selecting [Composite] in the USB connection
settings:
- Charge will not be possible if the recorder is
operating. Charge will start 1 minute after the
end of the operation.
- Charge may not be possible depending on the
application in use on the computer connected.
• In case you would like to charge using the
[Composite] setting, select [Optional] in the USB
connection settings, then connect the USB cable
to the recorder. Selecting [AC Adapter] at the
[USB Connect] display will enable you to charge
(
☞ P.48).
Cautions concerning the rechargeable batteries
Read the following descriptions carefully when you
use the Ni-MH rechargeable batteries.
Discharging:
Rechargeable batteries self-discharge while not in
use. Be sure to charge them regularly before use.
Operating 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.
Recommended 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
Using the rechargeable batteries 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 batteries
from the products when you will not be using them
for a long time, and store them separately.
Notes
• This recorder is designed to fully charge batteries
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.
• When disposing rechargeable batteries, always
observe the local laws and regulations. Contact
your local recycling center for proper disposal
methods.
• If Ni-MH rechargeable batteries are not fully
discharged, protect against short-circuiting (e.g.
by taping the contacts) before disposing.
