Notes
• Manganese batteries may not be used in
this recorder.
• When changing batteries, AAA alkaline
batteries or Olympus Ni-MH rechargeable
batteries are recommended.
• Be sure to stop the recorder before
replacing the batteries. Unloading the
batteries while the recorder is in use may
corrupt the file. If you are recording into
a file and the batteries run out, you will
lose your currently recorded file because
the file header will not be able to close.
It is crucial to change the batteries once
you see only one Hash mark in the battery
indicator.
• If it takes longer than 15 minute to replace
the dead batteries or if you take the
batteries in and out repeatedly at short
intervals, you may have to reset the time
when you have loaded fresh batteries
( P.20).
• Remove the batteries if you are not going
to use the recorder for an extended period
of time.
• When playing a voice/music file, the
recorder may be reset due to the
reduction of the voltage output of the
batteries depending on the volume level
even if [] is displayed in the battery
indicator. In this case, lower the volume of
the recorder.
• When replacing rechargeable batteries, be
sure to use Ni-MH rechargeable batteries.
The use of other manufacturers' products
can damage the recorder and should be
avoided.
