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-560V/455/450
Replace the batteries with new ones when the REC/BATT
(M-560V) or BATT (M-455/450) lamp dims.

For M-650V
Replace the batteries with new ones when the BATT lamps go
off and the E lamp flashes.

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-650V
only).

• In the following cases you do not need to replace the batteries:
– if the REC/BATT or BATT lamp flashes 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-650V only).

– if the E lamp flashes during FF (CUE) or REW (REVIEW) (M-650V

only).

be made using both sides of the MC-30 microcassette.

4 Set VOR to H, L or OFF (M-650V/560V only).

If you set VOR to H or L, the unit automatically starts
recording the sound and pauses when there is no sound
(you can save tapes and batteries).

Notes on VOR (Voice Operated Recording) (M-650V/560V
only)

• The VOR system depends on the environmental conditions. If you
cannot get the desired results, set VOR to OFF.

• When you use the unit in a noisy place, it 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 (not supplied) to EAR jack. The monitor
volume cannot be adjusted by VOL.

To prevent a cassette from being accidentally recorded

Connected Equipment
(M-650V only)

Recording with an External Microphone

Connect a microphone to the MIC jack. Use a microphone of low
impedance (less than 3 kΩ) 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.

To clean the tape head and path

Press n and wipe the head, capstan and the pinch roller with a
cotton swab, moistened with alcohol every 10 hours of use.

To clean the exterior

Use a soft cloth slightly moistened in water. Do not use alcohol,
benzine or thinner.

Specifications

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.

Precautions

dimension (see illustration) is different.

Standard

Only standard microcassettes
have a small indention of side A.

Approx. 5 mm

•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
