on a record (to later programs). The cartridge can move
until the key is released, and after once stopping there, it
moves down to the record if the play/cut key pushed.
Playing will! begin from there.
To skip the music in play and listen to the next program,
push the cartridge forward key during play. The cartridge
(stylus tip) will come off the record and move to the
beginning of the next program and begin playing automatic-
ally from there. If you continue to push the cartridge
forward key at the time, the forward APSS operates from
the location where your finger was removed and moves the
cartridge to the beginning of the track you want to listen to
and start playing automatically from there.
Also when the cartridge forward key is pushed during
APMS operation, the cartridge moves up the record and
skips forwardly to the beginning of the next program and
cancelled by pushing the key again.
10. APMS clear key
Enables to clear the conditions preset for APMS operation.
11. Loading key
Enables to open or close the turntable chassis: it is possible
even when the chassis is opening or closing.
SENSOR SECTION
1. Turntable chassis open/close sensor
There are two skeleton switches to detect whether the
chassis is opened or closed in the following way:
With the chassis closed, the skeleton switch SW205 turns on
while the skeleton switch SW204 turns off.
With the chassis opened, the switch SW205 turns off while
the switch SW204 turns on.
2. Tonearm rest position sensor
starts playing from there.
Cartridge reverse key
Enables to move the cartridge toward the optional portion 3
on a record (to previous programs). The cartridge can move
until the key is released, and after once stopping there, it
moves down to the record if the play/cut key is pushed.
Playing will begin from there.
The reverse APSS operation is the same as the forward
APSS operation mentioned above — with the only dif-
ference about the direction of locating the beginning of the
— program you want to listen to.
Also when the cartridge reverse key is pushed during APMS
operation, the cartridge moves up the record and skips
reversely to the beginning of the previous program and
starts playing from there.
Repeat play key
Enables to repeat play of side A or side B. The repeat play
The photointerrupter detects that the tonearm is at its
position (at right for side A, at left for side B).
. Tonearm position sensor
When the tonearm is out of its rest position, the gear drum
and photointerrupter operate together to produce pulses to
detect how far from the rest position the tonearm is situ-
ated.
