How The Auto Record Size Selection Works; Replacing The Stylus - Sony PS-LX55 Operating Instructions Manual

HOW THE AUTO RECORD SIZE SELECTION WORKS
When the START/STOP button is pressed, the tonearm goes
automatically into the lead-in groove, whether the record is 30 cm
or 17 cm. A beam from the lamp is transmitted through the holes on
the rubber mat and the platter to the photo detectors which ac¬
tivate the auto-record size selection.
Inner holes for
30 cm and
17 cm records
Platter
When a 30 cm record is to be played,
When a 17 cm record is to be played,
When there is no record on the platter,
both inner and outer holes are covered
so no beam is transmitted to the photo
detectors.
the inner holes are covered so a beam
is transmitted through the outer holes
to the photo detector.
a beam is transmitted through both
the inner and outer holes to the photo
detectors. Even If the START/STOP
button is accidentally pressed, the
tonearm does not lower.
When a 25 cm record is to be played,
the tonearm lowers to the same point
that it would if a 30 cm record were on
the platter, since both the inner and
outer holes are covered. To play a
25 cm record, move the tonearm over
the lead-in groove with the ARM
TRANSPORT buttons and press the
START/STOP button.
At the end of the record, the tonearm
will automatically return to the arm
rest.
When a transparent record is to be played,
a beam passes through both the inner
and outer holes to the detectors so the
tonearm does not lower onto the
record. To play a transparent record,
move the tonearm over the lead-in
groove with the ARM TRANSPORT but¬
tons, press the ARM LIFTER button to
lower the stylus and press the
START/STOP button.
In this case, auto-return will not ac¬
tivate at the end of the record. Press
the START/STOP button to return the
tonearm to the arm rest.
When a badly warped record is to be played,
a beam may pass through the holes to
the detector(s) and cause a malfunc¬
tion of the auto-record size selection.
REPLACING THE STYLUS
The stylus will lose its effectiveness and begin to damage records
after about 400 hours of use.
For the VL-45G cartridge (supplied with the PS-LX55C) an ND-145G
replacement stylus is available at your Sony dealer.
Handle the stylus carefully as it is very delicate.
Install the replacement stylus as follows.
Plug the cartridge into the tonearm and tighten
Detach the stylus assembly
and insert a new stylus into
the cartridge.
