ADJUSTMENT
1. Video Output (Luminance Signal) Adjustment
Do this adjustment after replacing a C.B.A.
Purpose: To maintain video signal output compatibility.
1. Connect the oscilloscope to the video output terminal and terminate at 75 ohms.
2. Adjust VR3501 so that the luminance signal (Y+S) level becomes 1000 mVp-p±20 mV.
Purpose: To maintain video signal output compatibility.
1. Connect the oscilloscope to the video output terminal and terminate at 75 ohms.
2. Adjust VR3511 so that the chrominance signal (C) level becomes 675 mVp-p±13 mV.

CAUTION: For continued safety,
replace safety critical components
only with manufacturer's recommend-
ed parts (refer to parts list). indi-
cates safety critical components. For
continued protection against risk of
fire, replace only with same type and
rating fuse(s). To reduce the risk of
electric shock, leakage-current or
resistance measurements shall be
carried out (exposed parts are accept-
ably insulated from the supply circuit)
before the appliance is returned to the
customer.
The DC voltage is an actual reading
measured with a high impedance type
voltmeter with no signal input. The
measurement value may vary depend-
ing on the measuring instruments
used or on the product.
