FEATURES
Linear tracking tonearm
A
linear
tracking
tonearm
is
designed
to
duplicate
the
movement
of
the
head
which
cuts
the
record
master.
Compared
with
a
pivoted
tonearm,
a
linear
tracking
arm
has
a
very
small
tracking
error
(which
means
greatly
reduced
harmonic
distor-
tion)
and
almost
no
pressure
on
the
inside
wall
of
the
groove
(which
means
improved
tracking
ability
and
channel
separation).
Front panel operation with the dustcover closed
The
ARM
TRANSPORT
buttons
allow
you
to
move
the
tonearm
easi-
ly
over
the
desired
point
of
the
record
with
the
dust
cover
closed.
Start/stop
of
the
record
play
and
tonearm
up/down
can
also
be
con-
trolled
using
the
buttons
on
the
front
panel.
Fully automatic system
The
movement
of
the
turntable
anc
the
tonearm
is
controlled
bya
microcomputer
and
is
activated
by
the
“feather-touch”
function
buttons
on
the
front
panel.
Automatic record size selection
The
record
size
is
automatically
set
by
a
photo
sensor
system.
If
no
record
is
on
the
turntable,
the
tonearm
will
not
descend
but
will
automatically
return
to
the
arm
rest.
Muting system
A
muting
system
activates
when
the
tonearm
is
lifted
and
is
deac-
tivated
after
the
tonearm
lowers
onto
a
record
so there
is
no
need
to
turn
the
amplifier
volume
down
every
time
a
stylus
is
placed
on
a
record.
Linear torque BSL motor
Direct
drive
system
with
Sony’s
unique
BSL
(brushless
and
slotless)
motor
which
has
an
extremely
low
noise
level
and
whose
smoothness
virtually
eliminates
wow
and
flutter.
Its
high
torque
assures
a
quick
start
to
33
'/3
rpm
after
only
a
half
revolution.
Synchronized operation with the Sony cassette decks
When
the
tonearm
lowers
onto
the
lead-in
groove
of
a
record,
the
cassette
deck
standby
mode
is
released
and
the
record
mode
assumed.
When
play
finishes,
the
cassette
deck
is
automatically
set
first
in
the
record
muting
mode,
then
in
the
pause
mode.
This
synchronized
operation
is
possible
with
Sony
cassette
decks
equipped
with
a
four-pin
remote
control
jack
which
is
connected
with
the
Sony
RM-65
synchro
remote
control
unit.

TIPS ON RECORD HANDLING
e@ Before playing, clean the record with a record cleaner or soft
cloth. If a spray cleaner is used, make sure that it has dried com-
pletely before playing the record. Playing the record before the
cleaner has dried may damage the record,
It is a good idea to clean the record again before putting it away.
@ Handle a record by its edges and do not touch the grooves.
Fingerprints on the record surface may encourage an accumula-
tion of dust, resulting in impaired tone.
@Use a commercially available anti-static spray to neutralize the
Static electricity on a record.
e@Avoid exposing a record to direct sunlight or sources of heat,
such as a hot-air duct.
@Store your records vertically. They should not be compressed.

SIZE SELECTION WORKS
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 piatter, 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 /ead-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 maifunc-
tion of the auto-record size selection.
Plug the cartridge into the tonearm and tighten
the cartridge locking screw firmly.
The screw cannot be
inserted from this side.
Detach the stylus assembly
and insert a new stylus into
the cartridge.

TRACKING FORCE FINE ADJUSTMENT
The tracking force has been correctly adjusted at the factory. Make
fine adjustment only when the tracking force is so light that the
stylus skips grooves.
Slide the tracking force adjustment lever
towards + (forward) for heavier tracking
force or towards — (backward) for lighter
tracking force.
SYNCHRONIZED PLAY OF THE TURNTABLE AND A CASSETTE DECK
— with an RM-65 synchro remote control unit connected
Record recording starts only when the START/STOP or ARM
LIFTER button is pressed. When the tonearm lowers onto the
Cassette decks which can be used with your turntable for
record, the cassette deck goes into the record mode and when the
tonearm is lifted up, the deck goes into the auto record muting
mode for four seconds, then into the pause mode.
this special synchronized operation are those Sony models
which are equipped with a 4-pin remote control jack.
An RM-65 synchro remote control unit (optional) is required
to connect the turntable and the cassette deck.
