When to replace the batteries
Replace the batteries with new ones of the same kind when the
REC/BATT lamp dims 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. Otherwise,
the built-in speaker may emit a loud noise and recordings may not be
made correctly.
• In the following cases you do not need to replace the batteries:
– if the E 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.
– if the E lamp flashes during FF/REW or CUE/REVIEW.

Note
Select the 2.4 cm tape speed for recording, if you play back the recorded

Notes on VOR (Voice Operated Recording)
• The VOR system is affected by the environmental recording conditions.
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. If you cannot get the results you want, set it to OFF.
• The VOR system may not record the beginning of the sound you want
to record because it starts recording only after it catches the sound. For
an important recording, set it to OFF.
To monitor the sound
Connect an earphone (not supplied) firmly to the EAR jack. The
monitor volume cannot be adjusted by VOL.
To prevent a cassette from being accidentally recorded
over
Break off and remove the cassette tabs. To reuse the cassette for
recording, cover the tab hole with adhesive tape.
Recording from Various Sound Sources
Notes
• When you are going to record something that you may not have an
opportunity to record again, test the unit first before you actually start
recording.
• When recording with an external microphone, the VOR system may not
work properly because of the difference in sensitivity.
Recording with an External Microphone
Connect a microphone firmly to the MIC jack.
M-673V : use the supplied microphone.
M-670V : use a microphone of low impedance (less than 3 kΩ).
When using a plug-in-power system microphone, the power to
the microphone is supplied from this unit.
Recording from another equipment
Connect another equipment firmly to the MIC jack using the
connecting cord (not supplied).
Set this unit to the recording mode and another equipment to
the playback mode.

• 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.
