Fe a t u re s  
The Sony BM-87DST dictator/transcriber is designed to be used for both dictating and transcribing.  
As a d ict a t o r  
• 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 t ra n scrib e r  
• 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.

Pre ca u t io n s  
• 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.

Pre p a ra t io n  
xNo t e s o n ca sse t t e s  
• Any standard cassette can be used, but the optional Sony leaderless cassette DC-60 or DC-90 is  
recommended. The use of a TYPE II (High position) or TYPE IV (metal) cassette is not advisable.  
• 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.  
Side A  
tab of side A  
Remove the broken tab.  
To reuse a cassette for recording after the tabs have been removed, simply cover each slot with a small  
piece of plastic tape. Do not stick any material on any other part of the cassette except the circled part,  
as illustrated below.  
Plastic tape  
* When the cassette is loaded for telephone recording with the tabs broken off and the TEL REC  
button is pressed, the beep tone is heard and the TEL REC button does not operate.  
When the cassette is loaded for dictating with the tabs broken off and the function selector is set to  
DICT, recording cannot be made and the beep tone is heard.

Useful Functions  
xLTR (le t t e r) sig n a l  
You can record electronic index signals on the tape with the HU-80 while the unit is set in the  
recording (dictating), telephone recording, stop or playback mode.  
LTR (letter=end of document) signal: Record at the end of each dictated material.  
When the Auto stop function (page 18) is activated (AUTO STOP:ON), the tape automatically stops at  
each index signal when it is rewound or fast forwarded. Dictated material can be located without the  
users having to listen to the entire tape.  
To record the LTR signal  
Press the LTR button on the HU-80.  
Each time the button is pressed, the LTR INDEX lamp (BM-87DST) lights up for about 3 seconds.  
LTR  
Notes  
• The LTR signal should be recorded with the intervals of more than 6 seconds.  
• Playback sound is muted while the LTR signal is recorded. However, the recorded material will be  
protected.  
• While the LTR signal is being recorded with the SPEED CONTROL selector set to ON, the tape will  
run at the normal tape speed.  
xMo n it o rin g w h ile d ict a t in g  
The recording can be monitored through the headphones. Connect the supplied stereo headphones to  
the i jack located on the left side of the unit. You can hear the sound in stereo through the stereo  
headphones. The sound is monaural through the built-in speaker. Adjust the VOLUME monitor if  
necessary.

xTa p e sp e e d se le ct o r  
With the TAPE SPEED selector, you can change the length of recording time on a cassette.  
When the TAPE SPEED selector is set to 4.8(centimeters/ second), you can record the normal length on  
a cassette. (i.e. 60 minutes using both sides of a 60-minute cassette.)  
When the TAPE SPEED selector is set to 2.4(centimeters/ second), you can record double the normal  
length on a cassette. (i.e. 120 minutes using both sides of a 60-minute cassette.)  
Note  
Tapes recorded in the TAPE SPEED 2.4 position cannot be played properly by a tape recorder without  
the TAPE SPEED selector function.

Tips for a More Efficient Dictating  
Before you start dictating  
• Organize your thoughts.  
• Make notes or an outline of what you want to dictate.  
• Check that the cassette is erased. (See page 21.)  
When you start dictating  
• Identify yourself. (Name, department, phone number, etc.)  
• Indicate the type of dictating. (Memo, letter, etc.)  
• Give transcribing instructions. (Type of stationery, number of copies, envelopes, etc.)  
• Specify distribution. (Name, addresses, etc.)  
During dictating  
• Relax and speak clearly, at normal speed.  
• Short sentences are best.  
• Include punctuation.  
• Spell difficult or unusual words.  
• Correct your mistakes. (Review and redictate.) (See page 15.)  
• At the end of each dictated material, record an LTR signal.

Useful Functions  
x Au t o st o p fu n ct io n  
With the Auto stop function, recorded documents can be located without the users 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.

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.
