7 Hold the metal counterweight to keep it from moving, then carefully rotate
the front black number ring so that 0 is in the 12 o'clock position.
8 Hold both the metal counterweight and black number ring together and
rotate them counter-clockwise so that 2.5 on the dial is in the 12 o’clock
position. This adjustment sets the tone arm to 2.5 grams of downward force
(the recommended tracking weight) for this needle.
Note: Do not turn the metal counterweight. The black number ring turns
separately.
