Setting tracking force
1. While supporting the counterweight so that it does not move,

with the centerline on the back of the tonearm.
• The tracking force is not adjusted simply by turning the tracking force
gauge ring.

2. Turn the counterweight and the tracking force gauge ring
together counterclockwise (to the left) until the centerline value
matches the recommended tracking force value for the cartridge
you are using.
• Refer to the cartridge maker's specifications for the recommended tracking
force value.
• The standard tracking force value for the cartridge provided with this
product is 3.0 g.
Setting the anti-skate adjustment
While the record is playing, a force acts on the stylus tip to pull it
inward. This force can be counteracted by setting the same values for
anti-skate and the tracking force.
Adjust the anti-skate control dial to have the same value as the tracking
force value.
• The standard tracking force value for the cartridge provided with this
product is 3.0 g.

components when the product is not in use. It should remain off
while records are playing.
