7. Adjustment of azimuth
To make azimuth adjustments, release the two screws locking the mechanism at the centre top
of the main tonearm tube, with Allen key 2mm. Under the main tube is a tiny rod with a
hexagonal screw. Insert the Allen key 2 mm into the screw (it may feel loose), rotate it
slightly and it will alter the azimuth. (Fig.2)
Rotating it back will bring azimuth to its previous position. Changes can be seen by
misalignment of the white lines on the top of the centre of the tube. Even 15 degrees rotation
of the Allen key will make a significant difference.
See appendix 2.
8. Bias
The bias should be adjusted roughly according to the tracking force. Using Allen key 1.5
mm, unlock the screw on the bias weight and position it to the equivalent of gap X to your
chosen tracking force. Lock the screw back, when in position.

For maximum tracking, it is advisable to set the bias by use of an appropriate test record, ie.
those with tracking bands. Please do not use test records with blank space where the tip of the
needle sits on the surface rather than in the groove. (Fig.9&9a)
