Battery precautions
• The voice recorder does not support
manganese batteries.
• Always turn power OFF before replacing
the battery. Files may be damaged if the
battery is removed while the voice recorder
is recording or performing an operation
such as erasing a file.
• If the batteries are removed from the
voice recorder, the [Time & Date] screen is
displayed automatically when the power
is turned on. See "Setting the time/date
[Time & Date]" (☞ P.55) for the procedure.
• When not using the voice recorder for
an extended period, always remove the
battery before storage.
• When replacing the battery, use an AAA
alkaline dry cell battery or an Olympus
nickel-metal hydride rechargeable battery
(model BR404).
• Even if the battery indicator is [
playback with the built-in speaker at some
volumes may result in a drop in battery
output voltage, causing the voice recorder
to reset. Lower the volume in this case.
• The battery indicator may differ between
when the internal memory is used and
when a microSD card is used.
• The continuous battery usage time is
reduced when using a microSD card
(☞ P.88).
• The continuous battery usage time will
vary depending on the performance of the
battery in use (☞ P.88).
• The [Battery] screen appears automatically
after you have replaced the battery. You can
also use a menu operation to display this
screen and set the battery (☞ P.55).
