1.
Setting up the tonearm:
Again check the height of the tonearm. The basic height should be such, that the centre of
the shaft (centre of vertical movement), is at the height of an LP on the platter. If there is
big difference, readjust the height of the armbase. If small (1 – 2mm), readjust by rotating
the VTA knob, after first unlocking the VTA lever.
Put the alignment protractor on the platter without a record. Be careful not to touch the
cantilever. Rotate the tonearm so that the base is parallel to and touching the narrow part
of the protractor. This will precisely position the tonearm. Fix the tonearm with the Allen
key 2.5mm. Due to its special construction, it is not necessary to overtighten.
Cartridge pins are: colours or other symbols:
Right (+) red
Left (+) white
Right ground (-) green
Left ground (-) blue
If necessary, due to the added weight of the tonearm, re-balance the turntable. Use a
spirit level to adjust horizontality of the turntable platter. If this is not possible readjust
the turntable support. Do note that spirit levels are not completely accurate. The turntable
should be horizontal, otherwise the tonearm will slide in one direction more than in
another.

Mounting the cartridge
With Allen screws 2.5mm, fix the cartridge onto the headshell. The position of the
needle should be in line with the end of the headshell when viewed from the side. Then
fix cartridge pins.
3.
Adjustment of tracking force
The counterweight is made from two parts. Rotating the counterweight position from one
red point to another, changes the tracking force for 0.1 grams. Locking is achieved by
holding the part which is nearest to the bearing and rotating the smaller part (view from
headshell) anticlockwise for about quarter of a turn. In the unlocked position rotation of
the counterweight is easy. To begin with, the tonearm should be balanced to zero tracking
force. This is not easy to achieve due to the very low friction in the bearing.
Heavy cartridges (above 15g): use a small counterweight which should be firmly
screwed by hand at the end of the threaded rod for counterweight.
Add tracking force by rotating the counterweight anticlockwise, then locking the
counterweight. Move the tonearm gently with the fingers in one direction, while the
cueing device is in the up (not play) position. The counterweight support will slide along
the cueing device rod with a certain friction. The tonearm will move to a certain distance.
Now repeat the same in the other direction. A big difference in the distance travelled
means that the tonearm is not horizontal. Try to adjust the level of the turntable again,
especially in the direction along the bearing shaft.
