Notes
• The VOR system depends on the environment conditions. If you cannot get the
desired results, set VOR to OFF.
• When using the VOR system, the unit starts recording only when a sound is
detected, therefore, the beginning of the word may not be recorded. For an
important recording, we recommend setting VOR to OFF.
To monitor the sound
Connect an earphone (supplied) firmly to the EAR jack. The sound for
monitoring cannot be adjusted by VOL.
Start recording during playback
Press r (record) during playback, recording starts immediately. It is useful
when you want to re-record the portion which was just recorded.
Review the portion just recorded
Push up CUE/0•)/REVIEW toward )REVIEW during recording.
Release the button at the point to start playback.
Recording cue markers
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, 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.
• During cue and review, the beep sounds differently.
• 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.
At the end of the tape
In the recording or playback mode, the tape stops at the end of the tape and
the locked buttons will be released automatically (Automatic shut-off
mechanism).
After fast forward or rewind, be sure to set CUE/0•)/REVIEW back
to the center.

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 y (standard microcassetes) with this unit. Non-

Fig. F)
Break out and remove the cassette tabs. To reuse the tape for recording,
cover the tab hole with adhesive tape.
•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.
•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 a long time, set it in the playback mode
and warm it up for a few minutes before inserting a tape.
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.
If you have any questions or problems concerning your unit, please consult
