*1 Longitudinal balance adjustment
While playing the record, the weight of the tonearm is supported by the arm
pivot and only tracking force is applied to the stylus tip. To accomplish this,
the tonearm must first be balanced horizontally, with the tracking-force indi-
cator set at "O".
*2 Tracking force
After the longitudinal balance adjustment, apply the recommended tracking-
force weight so that the stylus tip will trace the music groove accurately.
*3 Overhang
In record playing, because of the pivoted design of the tonearm, the stylus tip
can be perfectly tangent to the music groove at only one point of the record.
At all other portions of the record, there is a slight deviation of the stylus from
tangency. This is called the tracking error, and introduces minute errors in the
amplitude and timing of the reproduced signal as compared to the original, and
other forms of distortion which may be introduced depending on the cartridge
and stylus design.
Tracking error is minimized by the selection of an optimum "off-set" angle and
"overhang" distance. Overhang is the distance between the stylus tip and the
center spindle. This overhang adjustment is made at the time of installing a
particular cartridge, while the off-set angle is fixed by the manufacturer of the
tonearm.

*4 Anti-skating compensation
While playing the record, the frictional force between the record groove and
the stylus produces a force that tends to drive the tonearm toward the center
of the record. The anti-skating compensation cancels the above mentioned
force, and is applied in accordance with the tracking force.
Incorrect anti-skating compensation results in sound distortion and uneven wear
on both the stylus and the record.
TIPS ON RECORD HANDLING
Before playing
e@Clean the stylus, using a soft brush (stylus brush, artist's
paint brush, etc.). Brush the stylus from back to front. Never
clean the stylus with your finger tip.
e@For routine cleaning of records, the use of a barely damp soft
cloth (gauze, etc.) or a fluid type cleaner will be effective. If
a spray type record cleaner is used, make sure that the cleaner
has dried completely before playing the records. Record playing
before the fluid 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 don't touch the music
grooves. Finger prints on the record surface may induce an
accumulation of dust, resulting in impaired tone.
When record playing
@ It is recommended that you reduce the amplifier volume before
you lower the tonearm onto the record.
@While the turntable is energized, don't attempt to stop or
reverse the turntable by hand.
e@During play. be sure to close the dust cover.
anything on the dust cover.
e@While playing, never attempt to move the turntable or touch
the tonearm.
Don't place
After playing
@ Avoid exposing records to any source of heat, such as direct
sunlight, a hot-air duct, etc.
Store records vertically without applying any pressure or in-
clining to either side. This will minimize any warpage.
e@When not using the turntable close the dust cover.
Other precautions
e@Don't put anything but records on a turntable.
CONNECTIONS

@When connecting to an accessory ac outlet on the amplifier,
use an unswitched type outlet.
@When using the detachable power cord for the Type | turn-
table, first connect it to the AC INput of the turntable and then
to the ac outlet of the amplifier.
