Preparing Power Sources
Choose one of the following power sources.
Dry Batteries
Insert the # side
first for each
battery.
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).

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.
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
On power
•Operate the unit only on 3 V DC.
For AC operation, use the AC 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
unit. Non-standard cassettes cannot be used because their "L"
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
unit checked by qualified personnel before operating it any
further.
•Keep personal credit cards using magnetic coding or spring-
wound watches etc. away from the unit to prevent possible
damage from the magnet used for the speaker.
•When you do not use the unit for long, remove the batteries to
avoid damage caused by battery leakage and subsequent
corrosion.
•If the unit has not been used for long, set it in the playback
mode and warm it up for a few minutes before inserting a
cassette.
If you have any questions or problems concerning your unit,
please consult your nearest Sony dealer.
