AMSS SOLENOID ADJUSTMENT
AMSS (Automatic Music Select System) detects a silent space
(unrecorded portion) between each music on a musictape and
automatically plays back a desired music from the start.
The unrecorded portion should last for more than approximately
4 seconds.
It may not operate correctly in the following cases:
When the recorded sound is often interrupted as in a speech
tape.
When the silent space does not last long enough (less than 4
seconds).
When
there is an appreciable
noise in the silent space
between two adjacent programs.
When the unit is placed on a television set, AMSS may not
operaie correctiy due to adverse effect of the TV signal. In
this case, put the unit away from the television set.
If AMSS Solenoid is not correctly positioned, AMSS Switch does
not function correctly, F.FWD or Rewind button is released while
AMSS is working, or a button may not be locked. In this case,
perform the adjustment as follows:
1. Remove the Mechanism Chassis from the unit by following
its removal instructions.
2.
Loosen
the screw
fastening the Solenoid
and adjust the
Solenoid by moving it in the direction of the arrow, so that the
Plunger
Lever
is tightly attached
to the two absorption
surfaces of the Solenoid as illustrated.
