3. Put the disc (YEDS-18) in and press > button.
4. Confirm that the reading on the frequency counter
is locked at 4.3218 MHz.
Focus/Tracking Gain Adjustment
A frequency response analyzer is necessary in order
to perform this adjustment exactly.
However, this gain has a margine, so even if it is
slightly off, there is no problem. Therefore, this adjust-
ment is not recomended generally to be performed.
Focus/tracking gains determine the pick-up follow-up
(vertical and horizontal) relative to mechanical noise
and mechanical shock when the 2-axis device operate.
However, as these reciprocate, the adjustment is at
the point where both are satisfied.
@ When gain is raised, the noise when the 2-axis
device operates increases.
@ When gain is lowered, it is more susceptible to
mechanical shock and skipping occurs more easily.
@ When gain adjustment is off, the symptoms below
appear.
