Notes
Always use the dedicated USB cable that is
provided. Do not use a cable from another
manufacturer. Doing so could cause a failure.In
addition, do not connect the dedicated cable to
another manufacturer’s product.
Carefully insert the battery facing the right direc-
tion.
Be sure to turn of f the recorder before replacing
the battery. If the battery is removed while the
recorder is operating, a failure could occur (For
example, the recorder may become unable to
play files).
You may have to reset the time if the batter y is
removed from the recorder for 15 minutes or if
the battery is repeatedly removed and inserted
at short intervals ( P.27).
Remove the b attery if the recorder is not to be
used for a long time.
When you n eed a new battery, always purchase
the Olympus lithium ion battery (LI-50B). Do not
use a cable from another manufacturer. Doing
so could cause a failure.
When rechargin g the battery, turn on the PC
and connect the recorder using the USB cable.
The battery is not recharged if the PC is off or
in the standby, hibernation or auto-power-off
mode.
Do not use the USB hub to connect to the PC
when recharging the battery.
The battery indicator shows [<] when recharg-
ing is complete (Recharging time: about three
hours*).
* This is the approximate time when recharg-
ing an empty battery to the full level at the
room temperature.The recharging time varies
depending on the remaining battery level,
recharging state and other factors.
If [;] or [=] is displayed, the battery cannot be
recharged. The ambient temperature must be
between 5 C and 35 C to recharge the battery.
[;]: The ambient temperature is too low.
[=]: The ambient temperature is too high.
If the battery runs out ver y quickly even after
being recharged to the full level, replace it with a
new one.
Securely insert the USB connector all the way in.
The USB connector must be properly connected
to operate normally.
Recharging

4Discharge:

Because the lithium ion battery has self-discharge
characteristics, recharge the attached lithium ion
battery before using the product for the first time.

4Operating temperature:

The battery is a chemical product. Although the
battery performance varies even if the battery is
used in the recommended temperature range, this
variation is not a failure.

4Recommended temperature range:

When operating the recorder: 0 to 42 C
When recharging: 5 to 35 C
When storing the recorder for a long time: –20
to 30 C
Using the battery outside the above temperature
range could cause performance deterioration or a
shorter period of durability. If the recorder is not to
be used for a long time, remove the battery prior to
storage to prevent liquid leak or rust.
A new battery or a battery that has not been
used for a long time (one month or more) may
not completely recharge due to the nature of
lithium ion batteries. In such a case, repeatedly
recharge and discharge the batteries a few times.
Dispose of the battery according to applicable
laws.When disposing of the battery without
completely discharging it, insulate the battery
terminals with tape or take other measures to
prevent short-circuiting.
When the unit's [USB Class] is set to [Composite]
with the [USB setting], charging will not start
( P. 110).
If the battery runs out and you cannot change
the USB settings, connect the recorder via USB
while pressing and holding the STOP button for
around 10 seconds until a logo appears on the
display. The setting will switch automatically to
Storage allowing you to recharge the recorder (
P. 110).
