Cartridge downforce adjustment (Ortofon RS-Tonearm)
Remove the transport lock (3) from the tonearm. Store it in the original packaging so they are
available for any future transportation. Set the knob (5) to 0.
Place the counterweight (7) halfway along the counterweight support rod at rear of arm,
ensuring that the counterweight’s (7) securing screw uppermost. Lower the armlift and
position the cartridge in the space between tonearm rest (3) and platter. Carefully move the
counterweight (7) along the support rod, until the armtube (2) is balanced, i.e. floating level.
The arm should return to the balanced position if it is moved up or down. Do not forget to
remove the cartridge protection cap if fitted.
With the power off, and the platter static, place the supplied stylus pressure gauge onto the
platter.
Carefully lower the armlift and position the tip of the stylus on the pressure gauge’s
measuring tongue. The downforce will be displayed digitally.
Adjust the downforce, using the knob (6), to the cartridge manufacturer's recommendations.
This adjustment must be done with the tonearm resting on the tonearm rest (3). Finally secure
the counterweight with the securing screw (7).
The counterweight (7) supplied is suitable for cartridges weighing between 18-40g.
Anti-skating force adjustment (Ortofon RS and AS tonearms)
The anti-skating force must be adjusted corresponding to the downforce. Rotate the knob (5)
to adjust the anti-skating force. One mark on the scale represents 5mN (= 0.5g /0.5 Pond) of
downforce.
Adjusting the vertical tracking angle (VTA) (Ortofon RS and AS tonearms)
Put a record on the platter. When the stylus is lowered into the record groove and the tonearm is
not resting on the tonearm rest (3), the top surface of the cartridge body should be parallel to the
surface of the record.
