We are grateful for your choice of the Sansui SR-313 Belt-Drive Turntable.

and correct operation procedures.

FUNCTIONAL FEATURES
OSimplified Operation

The double-function Start Lift Lever serves also as the
power switch; it starts the platter retolving and engages
the mechanism that lifts and lowers the tonearm gently
to and from the spinning record.
ODirect Readout Stylus Pressure Dial

Stylus pressure adjustment is made easy by virtue of
the quick, fumble-free stylus pressure adjustment dial.
Olong-Wearing Knife-Edge Support

Thanks to the unique knife-edge system for vertical
plane, undue friction is not applied to the arm support,
allowing the arm to track the record groove faithfully
and smoothly over many years of use.

OFull-Accessory Tonearm Assures Faithful Tracing

The inside-force canceller and lateral balancer guar-
antee stable high fidelity reproduction by eliminating
unnatural stress on the tip of the stylus.
Olow-Capacitance Output Cables for Optimum CD4

Reproduction

The outputcables employed in your turntable are of
the lOchapacitance, shielded type Thus it can be used
to play CD-4 quadraphonic disks when a CD-4 com-
patible cartridge (or stylus) is installed.
ORemovable Dust Cover

It is recommended to keep the dust cover fitted to
the turntable when playing a record. To remove the
cover, simply slide it to the right and lift up.

I IMPORTANT PRECAUTIONS

Precautions Prior to Operation

To obtain optimum performance from your turntable,
observe the following precautions:

*Avoid exposing your turntable to (lust, Sunlight or
high temperatures.

*Place your turntable on a vibration-free surface.
iAvoid placing your turntable on an inclined surface.
otherwise tracing and performance characteristics will
deteriorate.

We sure that the platter surface is horizontal.

"Avoid subjecting the stylus and or tonearm to unrea-
sonahle stress. The tonearm of your turntable is not
rigidly fixed like conventional tonearms, but instead
adopts a knife-edge fulcrum system in the pivot portion
to ensure optimum tracing efficiency. Therefore, the
tonearm should be handled with extra»specia| care.
*Since the surface of the cabinet has been treated by a
special process, avoid cleaning with alcohol or thinners.
For best cleaning results use a diluted detergent and
water solution.

NOTE: If you purchased the SR-313 in the U.S./\.
or Canada, your turntable is to operate only at the AC
power voltage of 120V (usable between 110V and 130V)
and the frequency of GOHZ. Please note that a cartridge
is not provided with your turntable.

To Avoid Howling

Howling is a phenomenon where sound pressure and
vibration produced by the speakers are accidentally
picked up by the cartridge, amplified and reproduced
out of the speakers as feedback (distorted sound).
Howling can be recognized by a loud oscillating noise

heard while a record is being played on the turntable.
To prevent the vibrations from reaching the turntable,
avoid placing your turntable close to your speaker
system; do not use a common base for your turntable
and speakers; do not operate your amplifier or receiver
at excessively high volume levels.

Keep the Stylus Tip Clean

If dust or other foreign matter is allowed to collect on
the stylus tip, the tonal quality of the reproduced sound
will deteriorate and both the stylus and the record be-
ing played are likely to be permanently damaged.

Remove dirt or dust lodged in the record grooves with
a record cleaner from a reputable manufacturer; remove
dirt, etc, from the stylus tip with a soft-haired brush
from time to time. Avoid touching the stylus tip with
your finger or subjecting it to any shock: such mis-
treatment will shorten the life of the stylus or cause
damage,

Induced Hum

The high-performance cartridge on your turntable is
susceptive to the influence of magnetic fields, such as
may be produced by a large power transformer or a
nearby electric sewing machine, fan or other motor-
equipped appliance. If such conditions are present, a
loud hum noise may be heard. Hum can usually be
eliminated simply by moving the appliance in question
away from the vicinity of the turntable. To avoid the
influence of stray magnetic flux from the power supply
transformer of your amplifier or receiver, it is advisable
to install the turntable on the side of the amplifier
opposite to where its transformer is located.
