Anti-Skating Force (Bias)
The interaction of stylus friction and cartridge bearing
forces produces a force which pulls the tonearm to-
wards the centre of the record (referred to as skating
force). This force can be offset with the help of anti-skat-
ing force, which, in the case of the TP 92, is produced
by a magnet incorporated into the tonearm.
The anti-skating force is factory-adjusted. If neces-
sary, it can be readjusted with the help of an adjust-
ment screw.

Turn the adjustment screw anti-clockwise to increase,
and clockwise to decrease the anti-skating force. The
white dot above the adjustment screw indicates the set-
ting.
The amount of anti-skating force required depends
on the type of pick-up cartridge used. If you change
the cartridge for a different type, use a test record to
determine how much anti-skating force is required.
