recording the sound and pauses when there is no sound
(you can save tapes and batteries).
H: To record at meeting or in a quiet and/or spacious place.
L: To record for dictation or in a noisy place.
When the sound is not loud enough, set it to OFF, or the unit
may not start recording.
6 Press z.
nN is pressed simultaneously and recording starts. While
the tape runs, the REC lamp (M-830V) or REC/BATT lamp
(M-740V) lights and flashes depending on the strength of the
sound.

Notes on recording sides
•When recording on both sides, recording will not be made for a few
seconds while the tape is switching sides.
•When you open the cassette holder, the direction of the tape is reset to
the forward side.
•The DIR. switch cannot be used during recording.
Notes on VOR (Voice Operated Recording)
•The VOR system depends on the environmental conditions. If you
cannot get the desired results, set VOR to OFF.
•When you use the system in a noisy place, the unit will stay in the
recording mode. If the sound is too soft, on the contrary, the unit will
not start recording. Set VOR to H (high) or L (low) depending on the
conditions.
To monitor the sound
Connect an earphone to EAR jack. The monitor volume cannot
be adjusted by VOL.
To prevent a cassette from being accidentally recorded
over
Break out and remove the cassette tabs. To reuse the cassette for
recording, cover the tab hole with adhesive tape.
About This Manual
The instructions in this manual are for the M-830V and M-740V.
Before you start reading, check your model number. The M-
830V is the model used for illustration purposes. Any
differences in operation are clearly indicated in the text, for
example, “M-830V only”.
Preparing Power Sources
Choose one of the following power sources.
Dry Batteries
Make sure that nothing is connected to the DC IN 3V jack.
1 Open the battery compartment lid.
2 Insert two R6 (size AA ) batteries with correct polarity and
close the lid.
To take out the batteries
If the battery compartment
lid is accidentally detached
Attach it as illustrated.
When to replace the batteries
For M-740V
Replace the batteries with new ones when the REC/BATT lamp
dims.
For M-830V
Replace the batteries with new ones when the BATT lamps go
off and the E lamp flashes.
The BATT lamps change as illustrated.
Notes
•The unit will play back normally for a while, even after the E lamp
flashes. However, replace the batteries as soon as you can. If you do not,
the playback cannot be made with normal sound, noise may be
recorded and the recorded sound will not be loud enough (M-830V
only).
•In the following cases you do not need to replace the batteries:
– if the REC/BATT lamp, or BATT lamps flash with the playback sound
when you turn up the volume.
– if the E lamp lights momentarily when the tape starts running or at
the end of the tape (M-830V only).
– if the E lamp flashes during FF (CUE) or REW (REVIEW) (M-830V
only).

Polarity of the plug
Recording cue markers (M-830V only)
While recording, you can record a special signal on the tape to
mark a specific position.
At the desired position, press CUE MARKER to record a signal.
The REC lamp goes off and a signal will be recorded on the tape.
If you want to record a signal longer than that, press CUE
MARKER as long as you want.
During cue and review, you will hear the beep sound at the
signal position. During playback with the headphones plugged
in, you will hear the signal with low frequency sound at the
signal position.
Notes
•We recommend recording cue markers when there is a break in the
sound.
•The beep may sound differently depending on the marked position on
the tape because the winding speed varies from the beginning to the
end of the tape.
Playing a Tape
1 Insert a cassette with the side to start playing facing the lid.
2 Select the tape speed to the same speed as that used for
recording.
3 Press nN.
4 Adjust the volume.
At the end of the reverse side, playback stops and the unit turns
off automatically.
If you plug in headphones (not supplied) to the EAR jack, you
will get monaural output from both left and right channels.

to the center.
Recording/Playback with the
Connected Equipment
Recording from another tape recorder
Connect another tape recorder to the MIC jack using the RK-
G64HG connecting cord (not supplied).
Set this unit to the recording mode and another tape recorder to
the playback mode. In this case set VOR to OFF.
Recording with an External Microphone
Connect a microphone to the MIC jack. Use a microphone of low
impedance (less then 3 kilohms) such as ECM-T6 (not supplied).
When using a plug-in-power system microphone, the power to
the microphone is supplied from this unit.
Note
When recording with an external microphone, the VOR system may not
work properly because of the difference in sensitivity.
Precautions
On power
•Operate the unit only on 3 V DC.
For AC operation, use the AC power adaptor recommended
for the unit. Do not use any other type. For battery operation,
use two R6 (size AA) batteries.
On the unit
•Use only the (standard microcassettes) with this
unit. Non-standard cassettes cannot be used because their “L”
dimension (see illustration) is different.
•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 or disconnect the AC power adaptor, and have the
unit checked by qualified personnel before operating it any
further.
