Battery indicator
As the battery loses its remaining charge, the
battery indicator on the display changes as
follows:
• [ ] indicates there is little remaining
battery charge. Charge the battery or
replace it with a fresh one. When the
battery has run out, [ ] and [Battery
low] appear, and operation stops.
Rechargeable batteries
Read the information below carefully when
using a nickel-metal hydride rechargeable
battery (model BR404).
4 Discharging
Rechargeable batteries discharge naturally
when not in use. Be sure to charge the
battery before use.
4 Operating temperature
Rechargeable batteries are chemical-based
products. Their performance can vary
even when used within the recommended
operating temperature range. This variation
is normal.
4 Recommended temperature
ranges
When powering voice recorder: 0 to 42°C
(32 to 107.6°F)
When being charged: 5 to 35°C (41 to 95°F)
During long-term storage: -20 to 30°C (-4
to 86°F)
Use of a rechargeable battery outside the
temperature ranges above may result in
drops in battery performance or life. When
not using the voice recorder for an extended
period, remove the rechargeable battery
before storage to prevent fluid leakage or
rust.
NOTE
• Due to the nature of nickel-metal
hydride rechargeable batteries, new
batteries and batteries not used for an
extended period (one month or more)
may not charge completely. The battery
should become fully charged after
charging and discharging the battery
up to three times.
• Always dispose rechargeable batteries
in the legally prescribed manner. Before
disposing rechargeable batteries that
are not fully discharged, take steps to
prevent shorting such as insulating
their terminals with tape.
• When buying rechargeable batteries,
always select model BR404 nickel-
metal hydride rechargeable batteries.
Operation is not guaranteed if a battery
from another manufacturer is used.
• The continuous battery usage time of
a nickel-metal hydride rechargeable
battery that has been used repeatedly
will be reduced due to battery
degradation (☞P. 88).

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).
For users in Germany
Olympus has an agreement with the GRS
(Joint Battery Disposal Association) in
Germany to ensure environmentally-friendly
battery disposal.

Inserting/removing a microSD card
16
EN
The voice recorder has its own internal memory, and also supports standard microSD cards
(microSD, microSDHC) sold separately. If you insert a microSD card, the recording media
is switched automatically from the internal memory and recorded files are all saved to the
microSD card.
Inserting a microSD card
1While the voice recorder is in
stop mode, open the battery/
card cover.
• The microSD card slot is inside the
battery/card cover.
2 Insert a microSD card, making sure
it is placed correctly as shown.
• Insert the microSD card straight,
avoiding crooked insertion.
• Inserting a microSD card the wrong
way or crookedly could damage its
contact surface or cause it to jam in
the slot.
• A microSD card not inserted fully (until
it clicks into place) might not record
data.
3Close the battery/card cover.
• The recording media is switched
automatically to the microSD card.
TIP
• If you wish to record to the internal
memory, remove the microSD card
from the voice recorder (☞P. 17).
NOTE
• The voice recorder may not be able to
recognize a microSD card formatted
(initialized) for a PC or other device.
Before using a microSD card, always
initialize it on the voice recorder
(☞P. 58).

automatically to the internal memory.
NOTE
• MicroSD cards may pop out forcefully
on removal if you flick or release your
finger too quickly after pressing the
card in.
• Depending on the card’s manufacturer
and type, some microSD cards and
microSDHC cards may not be fully
compatible with the voice recorder and
not be recognized properly.
• For microSD card compatibility under
Olympus verification, please contact
our customer support at:
http://www.olympus-europa.com
Note that our customer support will
provide information on microSD card
manufacturers and card types for which
Olympus has verified operation, but
will not guarantee it's performance.
Also note that some cards may
no longer be recognized correctly
by the voice recorder in case
card manufacturer changes card
specifications.
• Read the operating instructions
provided with the card when using a
microSD card.
• If a microSD card is not recognized by
the voice recorder, try removing and
reinserting the card to have the voice
recorder attempt recognition again.
• Processing speed may be low for
some microSD card types. Processing
performance may also be reduced by
writing or deleting data repeatedly
from a microSD card. In this case,
reinitialize the card (☞P. 58).

Preventing accidental operation
18
EN
Setting the voice recorder to HOLD mode maintains the current operation and disables button
operations. HOLD mode is a handy feature for preventing unintentional operation from
accidental button presses when the voice recorder is carried in a bag or pocket. It is also useful
for preventing the voice recorder being accidentally stopped during recording.
Setting HOLD mode
1Slide the POWER / HOLD switch to
the [ HOLD ] position.
• [Hold] appears in the display, and the
recorder enters HOLD mode.
Releasing HOLD mode
1Slide the POWER / HOLD switch to
position Ashown below.
NOTE
• When any button is pressed during HOLD mode, [Hold] appears in the display for 2 seconds.
No other operation is performed.
• Setting HOLD mode during voice recorder playback (or recording) continues the playback
(or recording) operation and prevents any other operation from being performed. (The
voice recorder stops when playback ends or when recording ends because, for example,
there is no remaining memory space.)

When the voice recorder has been
stopped for at least 10 minutes (default
setting) after power ON, the display
disappears and the voice recorder
automatically enters the Power Save
mode.
• Pressing any button releases the
