Features
The Sony BM-87DST dictator/transcriber is designed to be used for both dictating and transcribing.
As a dictator
• The Sony HU-80 hand control unit (not supplied) remotely controls the BM-87DST
dictator/transcriber.
• Electronic index signal — “LTR” (letter=end of document) signal — can be recorded on a tape while
the unit is set in the recording (dictating), telephone recording, stop or playback mode.
• Alarm sound informs a recording error.
• Recording of telephone calls can be performed with the use of the optional telephone recording
adaptor.
• With the use of the supplied headphones, you can monitor the sound with the desired sound level
during recording.
Dictating
HU-80
(not supplied)
As a transcriber
• Auto stop function quickly accesses the dictated material.
• Auto backspace function with the REVERSE TIME control makes transcribing easy by enabling the
reviewing of the last recorded words each time the playback is resumed.
• Rapid erasing function with the z ERASE button and the j REW button.

Precautions
• Operate the unit only on 9 V DC.
For the AC operation, use the AC power adaptor supplied with the unit. Do not use any other AC
power adaptor as it may cause a malfunction of the unit.
• Unplug the AC power adaptor from the wall outlet when it will not be used for an extended period
of time. To disconnect the adaptor, pull it out by grasping the adaptor itself. Never pull it by the
cord.
• Do not place the unit in a location near heat sources such as radiators or air ducts or in a place
subject to direct sunlight, excessive dust, mechanical vibration or shock.
• Allow adequate air circulation to prevent an internal heat build-up. Do not place the unit near
materials (curtains, draperies, etc.) that may block the ventilation holes.
• Should any solid object or liquid fall into the unit, unplug the unit and have it checked by qualified
personnel before operating it any further.
• The supplied AC power adaptor becomes hot if it is connected to a wall outlet for a long period of
time. However, this will not cause any mechanical problems.
If you have any questions or problems concerning your unit that are not covered in this manual,
please consult the Sony dealer from whom you purchased the unit.

• Choose a cassette of suitable length. The recording time on each side of these cassettes is as follows:
Sony DC-60 approx. 30 minutes (4.8 cm/s)
Sony DC-90 approx. 45 minutes (4.8 cm/s)
• The use of cassettes whose running time is longer than 90 minutes (total time) are not advisable.
• The letter A on the Sony cassette is embossed to help you distinguish that side of the cassette in a
dimly lit area.
To prevent accidental erasure
When the unit is operated in the recording mode, any previous recordings will be automatically
erased. For this reason, cassettes incorporate a safety device to prevent any accidental erasure.
When the small tabs at the rear of a cassette are broken off, an interlock on the unit will be activated,
preventing recording.*
To protect the recording on side A, break off the tab of that side.
To protect the recording on side B, break off the tab of that side.

Transcribing
Useful Functions
x Auto stop function
With the Auto stop function, recorded documents can be located without the user’s having to listen to
the entire tape. This function activates only in the rewind or fast forward mode.
When the AUTO STOP selector is set to ON, the tape automatically stops at each LTR signal
previously recorded on the tape. (See “LTR signal” on page 14.)
Notes
• The tape does not stop at the LTR signal even if the AUTO STOP selector is set to ON while the J
FF button or the j REW button is continuously depressed.
• When the AUTO STOP selector is set to ON, the tape automatically stops at each SEC signal
previously recorded on the tape with the Sony Professional Dictation Machine.
When the AUTO STOP selector is set to OFF, the tape does not stop even if the electronic index
signals have been previously recorded.
Notes
• E-INDEX signal of the Sony conventional models corresponds to the LTR signal of BM-87DST.
• LTR signal and E-INDEX signal do not correspond to the cue signals used for the consumer type
tape recorder.
• Set the AUTO STOP selector to OFF to transcribe either a music cassette or a cassette which has not
been recorded with the Sony Professional Dictation Machine, otherwise the tape may automatically
stops in the rewind or fast forward mode.
x Controlling the speed
Set the SPEED CONTROL selector to ON to adjust
the tape speed with the SPEED control. The tape
can be played back at a speed faster or slower than
normal. Set the SPEED CONTROL selector to OFF
to transcribe the dictated material at the normal
speed.

x Auto backspace function
This function operates only when the supplied foot control unit is connected. With the use of the
REVERSE TIME control, the tape is rewound a little each time it is stopped. Then, the last few
recorded words can be reviewed when you resume playback. Adjust the REVERSE TIME control to
determine the length of the tape to be rewound. At “9” position, the tape is rewound so that the
dictated material can be reviewed for approximately 5 seconds*. At “0” position, the tape stops
without being rewound at all.
