Make sure that nothing is connected to the DC IN 3V jack.
1Open the battery compartment lid.
2Insert two size AA (R6) 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-545V/540V
Replace the batteries with new ones when the REC/BATT lamp dims.
For M-647V/645V/640V
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-647V/ 645V/640V 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-647V/645V/640V only).
–if the E lamp flashes during FF (CUE) or REW (REVIEW) (M-647V/ 645V/640V only).

House current
to the wall outlet
AC power adaptor (not supplied)
Connect the AC power adaptor to DC IN 3V and to a wall outlet. Use the AC power adaptor (supplied with M-645V only) or the AC-E30HG AC power adaptor (not supplied) . Do not use any other AC power adaptor.
Polarity of the plug
Note
Specifications for AC-E30HG vary for each area.
Check your local voltage and the shape of plug before purchasing.
Rechargeable batteries (supplied with M-645V only)
Charge the rechargeable batteries only with the supplied charge adaptor and the AC power adaptor. The rechargeable batteries can be charged approximately 500 times.
Be sure to charge the rechargeable batteries for approximately 8 hours before using them. The unit can be used for recording for approximately 6.5 hours with the fully charged rechargeable batteries.

Notes
•Use the supplied two rechargeable batteries only with the supplied charge adaptor.
•If there is distortion of sound or excessive noise, or if the unit does not operate properly, turn off the unit and recharge the two rechargeable batteries together.
•The rechargeable batteries will discharge even when not in use. Be sure to charge them before use.
•Recharge the two rechargeable batteries together. Otherwise, the charging cannot be done.
•Be sure to remove the rechargeable batteries from the charge adaptor to avoid overcharging (more than 20 hours) when charging has been completed.
•Charging and operation should be made in temperature ranges 5°C to 40°C (40°F to 104°F).
•The charge adaptor will become warm during charging but this is not a sign of problem.
•Do not use or leave the charge adaptor in a location near heat sources or in a place subject to direct sunlight or excessive moisture.
•Unplug the AC power adaptor from the wall outlet when it is not to be used for long.
•Do not attempt to charge dry batteries.

1Press the reset button of the TAPE COUNTER.
2Press xZ and insert a standard microcassette with the side to start recording facing the lid
3Select the desired tape speed.
2.4cm for optimum sound (recommended for normal use): A 30-minute recording can be made using both sides of the MC-30 microcassette.
1.2cm for longer recording time: A 60-minute recording can be made using both sides of the MC-30 microcassette.
4Set VOR to H, L or OFF.
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).
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.

Note
Select the 2.4 cm tape speed for recording, if you play back the recorded tape with another unit. Otherwise, the sound quality may be changed.
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 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.

If the tape is completely wound or rewound while searching forward/ backward during playback (CUE/REVIEW), the mCUE/MREVIEW switch may not return to the center position when you release the switch. In this case, push back the switch to the center to start playback.
If you plug in headphones (not supplied) to the EAR jack, you will get monaural output from both left and right channels.
To increase the playback speed (M-647V/645V/640V only)
Slide the FAST PB switch in the direction of the arrow. The playback speed will be increased.
To return to the original speed, slide the FAST PB switch to the original position.
At the end of the tape

After fast forward or rewind, be sure to set mCUE/ MREVIEW back to the center.
Recording/Playback with the Connected Equipment (M647V/645V/640V only)
Recording from another tape recorder
Connect another tape recorder to the MIC jack using the RKG64HG 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.
M-647V for the United States : use the supplied microphone. Other models : use a microphone of low impedance (less than 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 adaptor recommended for the unit. Do not use any other type. For battery operation, use two size AA (R6) 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.
•Keep personal credit cards using magnetic coding or springwound 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.
