Го economize the tapes and batteries
let the VOR switch to ON. The tape moves only when sound is

lictating.

dease it at the desired point.
Ifhen a beep sounds and the DICT/BATT lamp goes out
he tape reaches the end. Slide the function lever to STOP.
Putting Marks during Recording for Easy
Access (BM-577 only)
Press E-INDEX lightly when you have special instructions for your 
secretary about the material or mark the end of the letter. An 
electronic index signal will be recorded on the tape.
This signal is the same as the LTR signal of the Sony transcriber. 
When your secretary uses the Sony transcriber equipped with auto
stop function, the tape automatically stops at each index signal 
when it is rewound or rapidly advanced. Your secretary will be 
able to search a necessary dictation easily.
Note
The cue-maker function of some Sony microcassette-corder may not operate
on the electronic indexing mark recorded with the BM-577, because the cue-
maker function and the electronic indexing function have no effect each
other.
Dictating with an External Microphone or with
Telephone Recording Adaptor
Connect the microphone to the MIC jack. When connecting the 
electret condenser microphone with "plug-in power" system, the 
power of the microphone is supplied from this unit.
For telephone recording, connect the TL-4 telephone recording 
adaptor (not supplied) to the MIC jack. For details, refer to the TL-4
