Basic Operations
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.
HQ*
7 h. 30 min.
SP**
20 h. 5 min.
LP***
37 h. 5 min.
(h.: hours/min.: minutes)
* HQ: High quality recording mode
(monaural sound)
** SP: Standard play recording mode
(monaural sound)
***LP: Long play recording mode
(monaural sound)
Notes
• To record in better sound quality,
select the HQ 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 vary depending on the
conditions of use.
• When you record messages in the
mixture of HQ, SP and LP mode, the
maximum recording time will be
between those for the HQ and LP
modes.
• Due to the limitation of the IC
recording system, this unit records
in the minimum recording unit of
approx. 2 seconds at most, therefore
the following symptoms may occur:
– When a message is shorter than
the minimum recording unit, it is
still counted as approx. 2 seconds
at most 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.
The memory is
nearly full.
Flashing
When the remaining time of
recording reaches 5 minutes, the
last one of the indication flashes.
If the remaining recording time
display mode is selected, the
remaining recording time display
will also flash when the remaining
time reaches 1 minute.
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
zX
REC/PAUSE 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
zX
REC/PAUSE after
you have recorded 99 messages,
“FULL” will flash with an alarm
sound. Select another folder or erase
some of the messages.
Starting recording

to the sound — Advanced
VOR function
When VOR (voice operated
recording) is set to “ON” in the
menu, recording starts when the
recorder detects sound. (“VOR” is

Recording stops when no sound is
heard. (“VOR PAUSE” flashes in
the display window.)
Note
VOR function is affected by the sound
around you. Set the microphone
sensitivity to “H (high)” or “L (low)”
using the menu. If recording is not
