2) C u e the arm s u c h that the stylus

front, there s h o u l d be a n even angle
reflection from the surface. If not, use a
flat screwdriver a n d s c r e w c l o c k w i s e to
tilt the cartridge t o w a r d s the right, a n d
counter-clockwise to tilt it t o w a r d s the

reached, tighten

NOTE: If a major correction has been
required, the VTA adjustment
be redone.

Anti-skating Adjustment

Due to the nature of tonearm geometry,
the groove tends to pull the stylus
towards the centre of the disc and s o m e
amount of force should b e applied in
the opposite direction to counteract
this. This a m o u n t varies according to
the tracking force and the type of stylus
shape e m p l o y e d .
This amount of anti-skating force can be
increased b y sliding the w e i g h t along
the L structure located at the bottom
right of the tonearm base, to give the L
more leverage, or decreased b y sliding
it towards the arm base.
In order to determine the amount of
anti-skating force required visually, exa­
mine the stylus a n d c o m p a r e its posi­
tion relative to the cartridge b o d y w h e n
at rest and w h e n playing the groove. If it
inclines t o w a r d s the centre of the disc,
increase the anti-skating; if it inclines
towards the outside grooves, decrease
the anti-skating.
A n insufficient a m o u n t of anti-skating
audibly manifests itself as right-channel
distortion. If there is too m u c h anti-
skating, the left channel will be more
prone to break-up.
NOTE: We recommend
the use of a
test disc to determine
the optimum
amount of anti-skating.
Consult your
dealer.

Attaching the Dust Cover
1) Locate the dust cover a n d hinge
assemblies.
2) Place the dust cover upside d o w n o n
your work surface w i t h the back (the

3) U s e a Phillips screwdriver to remove
the s c r e w s from the hinge a s s e m b l y .
4) Place the hinge against the outside
of the dust cover w i t h the angled hinge
facing a w a y from the cover. Position the
loose metal plate on the inside of the
cover, align the holes, insert the s c r e w s
and tighten moderately.
5) S e t the turntable s o that the rear

Motor Angle Adjustment

Before proceeding with this adjust­
ment, verify that the acrylic
and the subchassis are still level.
Three s c r e w s hold the motor in place.
