*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.

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.

precautions
e@Don't
put anything
