The stylus lead-in position has been adjusted at the factory
so that the stylus lands correctly onto the lead-in groove of
a record. However, the position may need adjustment if
the tonearm is replaced. Follow these steps to adjust the
lead-in position:
1. Put the 30cm JVC test record (RG324) on the platter.
2. Set the RECORD SIZE select knob to ‘17’, and start
automatic playing. If the stylus comes in contact with
the test record while the voice is counting In a range
between 7 and 29, the lead-in position is correct. If not,
turn the adjustment screw with a screwdriver clockwise
to move the lead-in position towards the center of the
record, where the lead-in count increases, or counter-
clockwise to move the lead-in position towards the outer
rim of the record, when the lead-in count decreases.
Note: The normal lead-in count range is shown below. If
you adjust so that the lead-in count is 18 for a 1/cm
record the lead-in count for both 25cm and 30cm
records will be automatically set within the normal
range.

* If lead-out does not occur:
Play the 17cm JVC test record (RG652) having a
lead-out groove pitch of 3mm. If the change cycle does
not begin when the stylus reaches the lead-out groove,
turn the lead-out adjustment screw clockwise in the
direction of arrow (a) as shown in Fig. 21.
If lead-out occurs too soon:
If the change cycle begins before the stylus comes to the
lead-out groove of the 17cm JVC test record (RG653,
back side of RG652) turn the screw counterclockwise in
the direction of arrow (b).
Caution: Unplug the power cord first.
1. Clamp the tonearm to the arm rest.
Remove the dust cover.
Remove the rubber mat, the platter, and the belt.
Turn the set upside down, and place it on blocks to
protect the tonearm assembly, spindle shaft and pulley.
After removing the signal and power cord assemblies
from the bottom board, remove the eight screws fixing
the bottom board.
