4-1-6 Focus offset adjustment
Adjst the V402 (F. BAL) so that the jitter of the
waveform at the TP—1 pin (8) becomes minimum.
Then, set the player into stop mode, and measure
the voltage between the TP—1 (1) and GND.
Check that the voltage is between 10 and 50 mV.
If the voltage is outside this range, readjust it so
that the jitter becomes ‘optimum within this range.
Specification: 30ns or less. (See Fig4—-5,4—-6)

4-1-7 Focus gain adjustment
1 ) Input a 1.2-kHz, 400m Vp-p signal from the
external oscillator to TP—1 pin (4) via a 4.7-
kohm_ resistor.
2 )Adjust V405(F.GAIN)so that the gain difference
between the signal at TP—1 pin (3) and that one
for the external OSC becomesO dB. inctor
4-1-8 Tracking gain adjustment
1 ) Input a 1.2-kHz,
external oscillator to TP~1
4.7—kohm resistor.
2 ) Adjust V404 (T.GAIN) so that the gain
difference between the signal at TP—1 pin (5)
and the one for the external OSC becomes 0 dB.
