Tracking Force Adjustment
1. Remove the stylus cover.
2. Slide the anti-skating knob to align its index mark with
the "'O'' mark. (Fig. 15)
3. Slide the counterweight
to the middle of the weight
shaft and turn until the tonearm is balanced with the
stylus nearly touching the record surface. (Fig. 19, 20)
4. Hold the counterweight at the adjusted position and turn
the tracking force dial until the ''O'' mark is aligned with
the index line on the tonearm weight shaft. (Fig. 16)
* It is most important to obtain the correct tracking
force.
5. Turn the counterweight in the direction O-1-2 until the
"4.75"
(for the JVC MD1055II)
mark on the tracing
force dial is aligned with the index line. (Fig. 17)
*
Be careful not to touch the tracking force dial when
turning the counterweight.
* Turning the tracking force dial alone has no effect on
the tracking force.
6. Slide the anti-skating knob until the index mark of the
knob points to ''1.75'' (JVC MD10551I) mark (Fig. 18)

Overhang Adjustment (Fig. 21)
Adjust the overhang as shown, aligning the center lines of
the cartridge and the headshell. Leave 32 mm between the
stylus tip and the edge of the headshell as shown. An error
of +1 mm will not degrade performance.

Tonearm Elevator-height Adjustment (Fig. 22)
The optimum clearance between the stylus tip and the plat-
ter mat is about
8 mm when the tonearm is resting on the
tonearm
elevator (with the UP/DOWN
knob switched to
the
UP position). Turning the adjusting screw
clockwise
lowers the height of the tonearm
elevator and turning it
counterclockwise increases it.
