5. Clock Check and Adjustment.
Set as above, then:
1) Set FACTOR A to xO.25
2) Connect a FREQUENCY COUNTER to TP-4A on
KLM-6000 and confirm if the value is
170.64KHz ±8KHz.
3) Adjust VR105 if necessary.
4) Set FACTOR A to x 1 and confirm if the value is
42.66KHz ±2KHz.
5) Adjust VR104 if necessary.
6) Change FACTOR A from x 0.25 to x 1 to confirm if
the value are in the range specified as above.
Repeat 2) - 4) till you get correct value.
7) Do the same adjustment for UNIT B usnig VR204
and VR205.

6. Analog Compressor/Expnder Check and Adjustment.
Set as above, then:
1) Input a Tone Burst wave (400Hz, -40dBm, sine
waveform) to SDD-1200 UNIT A and confirm
waveform (fig. 5) with an Oscilloscope (DC
0.5v/div, 10ms/div) connecting to MIX OUTPUT.
2) Confirm if the DC fluctuation of *3 shown in Fig. 5
is minimized. Adjust VR102 on KLM-6000 if
necessary.
3) Confirm if the linearity of *2 shown in fig. 5 is
almost linear. Adjust VR103 on KLM-6000 if
necessary.
