STYLUS FORCE ADJUSTMENT
Appropriate stylus force must be
obtained to let the stylus trace the
groove correctly. Incorrect setting
of the stylus force may cause the
system to skip grooves or affect
the reproduced sound quality.
1. Lower the cueing stick.
2. Move the counterweight for¬
ward and backward so that the
tonearm will be balanced horizon¬
tally. When balanced, the head shell
is raised and the tonearm parallels
the main body with the tonearm
base as fulcrum. (Caution: Be
careful not to drop the stylus or hit
it against the platter or other
objects.)

3. Return the tonearm onto the
arm rest. Turn the gauge ring of
the counterweight so that 0 point
falls on the reference marker on the
tonearm.
4. Turn the counterweight to pre¬
set the reading on the gauge to the
designated stylus force of your
cartridge. Do not touch the gauge
ring, as it will turn with the counter
weight.

5. Turn and set the anti-skating
knob to the value same as the stylus
force of your cartridge. Stylus
force adjustment is now com¬
plete.
PLAY
1. Place a record on the platter.
Use the EP adaptor when playing
records with a large center hole.
2. Set the speed selector to the
rpm of the record to be played.
3. Lift the cueing stick and swing
the tonearm carefully to a position
directly over the starting grooves of
the record. This will turn the power
on.
4. Check to see that the stylus is
over the record. Lower the cueing
stick to start transcription.
If you wish to stop the turntable
midway through a record, press the
REJECT button. The tonearm will
return to the arm rest automati¬
cally and the power will be turned
off.
5. When the transcription is fin¬
ished, the tonearm will return to
the arm rest automatically and the
power will be turned off.
MAINTENANCE
1. Keep the stylus tip clean of
dust. Clean the stylus carefully us¬
ing a soft brush, and also clean
the record before commencing
play.
2. The stylus tip is very sensitive.
Be careful not to touch it with a
finger or do not let it come in con¬
tact with solid matters.
3. The stylus is usually good for
about 500 to 1,000 hours of con¬
tinuous playing. A worn stylus will
cause the sound to be distorted and
the record to be damaged. Be sure
to use the correct replacement
stylus matching to your cartridge.
4. Do not move the turntable
when it is operating.
Never try to stop the platter forci¬
bly by hand while it is rotating.
5. When replacing cartridge of
stylus, make sure the power cord is
unplugged.
6. Lubrication is unnecessary. Con¬
sult your dealer if necessity arises.
7. Keep the unit always clean. Use
a soft dry cloth to clean the cabinet
and the dust cover.
HOWLING AND HUM
Howling is usually caused by vibra¬
tion of speakers which affects the
sensitive cartridge. If such pheno¬
menon occurs, relocate the turn¬
table or speakers away from each
other as much as possible. Hum is
usually caused by the nearby appli¬
ances utilizing transformers or
thermostat.
Relocating the unit away from the
noise sources will readily solve the
problem.
