2-7. Service mode
This mode facilitates adjustment of reel motor speed and
head azimuth.
Procedure :
Take out the cassette. Turn on the POWER switch while
pressing the REW and AUTO COPY buttons.
Keep pressing both buttons, and when the SHORT TAPE
indicator goes off after about 4 seconds, release the AUTO
COPY button. (At this time, do not release the REW button.)
Further after 2 seconds, make sure that the SHORT TAPE
indicator comes on again and the service mode is activated,
then release the REW button.
The following operation is available.
AUTO COPY : Same status as the COPY, with exception
that the bias dose not rise up. Accordingly,
the azimuth can easily be checked when
the record head is connected directly to
the playback amplifier.
COPY :
The COPY status is maintained, so that
the take up reel and plunger circuit can be
checked.
REW :
The REWIND status is maintained,
so that the supply reel circuit can be checked.
Note : In the COPY and REWIND modes, the shutoff and brake circuit do
not function. If a cassette tape is inserted, the reel motor can be
damaged at the end of tape. Therefor never insert a cassette tape.
