5) Turn RV5609 <BH, GAIN> and adjust so that “90 IRE ~
100 IRE” might be “65
±
10 mV”
(RV5609 can be adjusted at mechanical center of the VR
to obtain above metioned condition. In case that “100 IRE
~ GND” is above 3.7 V Adjustment is N.G)

(6) IC level adjustment (R ch)
1) Change to “WIDE Mode”.
2) Input PAL double speed signal 10 step waveforms.

3) Add 0 V to TP5211 <RLBS> and 9 V to TP5210 <RHBS>
by DC power supply.
4) Adjust the level by RV5205 <R-GAIN> as “0 IRE ~ 100
IRE” on TP5203 <R-sig2> is 1.50
±
0.02 Vp-p.

5) Adjust by RV5206 <R-BIAS> so that “Positive polarity 0
IRE ~ Negative polarity 0 IRE” might be 6.2
±

7) By RV5204 <R-S, GAIN2> & RV5208 <R-S, BIAS2>,
adjust the waveform for TP5204 <R-sig3> to the wave-
form for TP5203 <R-sig2>. (within
±
0.02 V)
6) By RV5203 <R-S, GAIN1>, RV5207 <R-S, BIAS1>, ad-
just the waveform for TP5202 <R-sig1> to the waveform
TP5203 <R-sig2>. (within
±
0.02 V)

B ch 1.50 ± 0.02 Vp-p
8) Confirm that the waveform for TP5203 <R-sig2> is
within standard mentioned.
(7) IC Level Adjustment (G ch)
1) Proceed 4) ~ 8) by the same way as R ch.
2) Proceedure 3) to add external voltage must not be done.
As for “related VR” and “output terminal” please refer to
the Fig.
