To perform the synchro pausing operation:
While the player is playing, if its cue key is pushed, the tone-
arm is lifted off the record to stop playing temporarily. Then
there appears a low level pulse (200m sec) at pin (6) of the
microcomputer
to turn off Q207 so that a high level pulse
(200 msec) goes out of pin (B)of DIN socket. With this pulse
given,
the cassette
deck enters record/pause
mode
to stop
recording temporarily.
Automatic Stop Function:
While the player is playing, if the function selector switch of
the amplifier
SA-107H
is set to other
than
the "player"
position, there appears a high level signal at the amplifier to be
applied to pin (4) of DIN socket of the player. This pulse is
sent to the base of Q206, and with Q206 turned on a low
Level pulse is caused to be applied to pin
of the micro-
computer. Then the microcomputer causes the player to stop
playing automatically.

TRACKING
ADJUSTMENT
1. Turn on the power switch without a record being put in the
compartment, push the cartridge forward key first and then
the cue
key to have the tonearm
moving
down
to the
turntable surface.
2. Turn the semi-variable resistor VR205
clockwise to move
the tonearm
in the inner direction, and turn it back until
the tonearm
will
be stopped:
at this position,
fix the
semi-variable resistor.
