Precautions

On power

• Operate the unit only on 3 V DC. Use two LR03 (size AAA)

alkaline batteries.

On safety

• Do not operate the unit while driving, cycling or operating

any motorized vehicle.

On handling

• Do not leave the unit in a location near heat sources, or in a

place subject to direct sunlight, excessive dust or mechanical
shock.

• Should any solid object or liquid fall into the unit, remove

the batteries and have the unit checked by qualified
personnel before operating it any further.

On noise

• Noise may be heard when the unit is placed near an AC

power source, a fluorescent lamp or a mobile phone during
recording or playback.

• Noise may be recorded when an object, such as your finger,

etc., rubs or scratches the unit during recording.

On maintenance

• To clean the exterior, use a soft cloth slightly moistened in

water. Do not use alcohol, benzine or thinner.

If you have any questions or problems concerning your unit,
please consult your nearest Sony dealer.

Backup recommendations

To avoid potential risk of data loss caused by accidental
operation or malfunction of the IC recorder, we
recommend that you save a backup copy of your recorded
messages on a tape recorder or to a computer, etc.

Current folder

Press FOLDER to
display the folder in
which you wish to
record messages.

Note on recording

Noise may be recorded if an object,
such as your finger, etc., accidentally
rubs  or scratches the unit during
recording.

Maximum recording time

The maximum recording time of all
the folders is as follows.  You can
record messages for the maximum
recording time in a single folder.

SP*

LP**

9  h. 40 min.

15 h. 45 min.

(h.: hours/min.: minutes)
*  SP: Standard play recording mode

(monaural sound)

** LP: Long play recording mode

(monaural sound)

Notes

• To record in better sound quality,

select the SP mode.  For switching
the recording mode, see “Changing
the Recording Mode” on the reverse
side.

• Before making a long recording, be

sure to check the battery indicator.

• The maximum recording time and

the number of messages you can
make varies depending on the
conditions of use.

• When you record messages in the

mixture of SP and LP mode, the
maximum recording time will be
between those for the SP and LP
modes.

• Due to the limitation of the IC

recording system, this unit records
in the minimum recording unit of
approx. 9 seconds, therefore the
following symptoms may occur:
– When a message is shorter than

the minimum recording unit, it is
still counted as approx. 9 seconds
so the remaining recording time
will decrease by more than the
actual length of the message.

– When the message is longer than

the minimum recording unit, the
remaining recording time  will
decrease by more than the actual
length of the message if it cannot
be divided by the minimum
recording unit without a
remainder.

– The sum of the number on the

counter (elapsed recording time)
and the remaining recording time
may be less than the unit’s
maximum recording time.

Remaining memory
indication

During recording, the remaining
memory indicator decreases one by
one.

When the remaining time of
recording reaches  5 minutes, the
last one of the indication flashes.
When the remaining time of
recording reaches 1 minute, the
selected display mode and
“REMAIN” will flash one after the
other in the display window. When
the memory is full, recording
automatically stops and “FULL”
will flash in the display window
with an alarm sound. To continue
recording, first erase some of the
messages.

Notes

• If you press 

z

REC/STOP when the

memory is full, “FULL” will flash
with an alarm sound. Erase some of
the messages before you start
recording again.

• If you press 

z

REC/STOP after you

have recorded 99 messages, “FULL”
will flash with an alarm sound.
Select another folder or erase some of
the messages.

Troubleshooting

Before taking the unit for repair, check the following
sections.  Should any problem persist after you have
made these checks, consult your nearest Sony dealer.

The unit does not operate.

• The batteries have been inserted with incorrect

polarity.

• The batteries are weak.
• The buttons are locked with the HOLD switch. (If

you press any button, “HOLD” will flash three
times.)

No sound comes from the speaker.

• The ear receiver or headphones are plugged in.
• The volume is turned down completely.

“FULL” is displayed and you cannot start
recording.

• The memory is full. Erase some of the messages.
• 99 messages has been recorded in the selected

folder. Select another folder or erase some of the
messages.

Noise is heard.

• An object, such as your finger, etc., accidentally

rubbed or scratched the unit during recording so
that noise was recorded.

• The unit was placed near an AC power source, a

fluorescent lamp or a mobile phone during
recording or playback.

• Plug of the connected microphone was dirty when

recording. Clean the plug.

• Ear receiver/headphones plug is dirty. Clean the

plug.

Recording level is low.

• Press MIC SENS to display “HIGH”.

Recording level is unstable (when recording
music, etc.).

• This unit is designed to automatically adjust the

recording level when recording meetings, etc., and
is not suitable for music recording.

“--Y--M--D” or “--:--” is displayed.

• You have not set the clock.

“--Y--M--D” or “--:--” is displayed on the
recorded date or recorded time display.

• The date and time of recording will not be

displayed if you recorded the message when the
clock was not set.

You cannot divide a message.

• You cannot divide a message in a folder which has

99 messages.

• If you divide messages frequently, the unit may

become unable to divide a message.

• You cannot divide a message in the first or the last

1 second of a message.

You cannot combine a message.

• If you combine messages frequently, the unit may

become unable to combine messages.

You cannot record messages up to the
maximum recording time.

• If you record messages in a mixture of SP and LP

modes, the recordable time varies from the
maximum SP mode recording time to the
maximum LP mode recording time.

• No more recording can be made when 99 messages

each have been recorded in a folder.

• Due to the limitation of the IC recording system,

this unit records in the minimum recording unit of
approx. 9 seconds. If the length of each message
cannot be divided by the minimum recording unit,
the remaining recording time may decrease by
more than the total length of the messages.

The remaining time displayed in the display
window is shorter than that displayed in
the supplied “Digital Voice Editor“ software.

• The unit requires a certain amount of memory for

system operation. That amount is subtracted from
the remaining time, which is the reason for the
difference.

The unit does not operate correctly.

• Take out the battery and insert it again.

Please note that recorded messages may be erased
during service or repair work.
