2. OXIDE Y/C Check

During play back the alignment tape in PLAY mode,

check the white level of Y signal.

If the specification is not satisfied, adjust it.

PB portion:

75% color-bar signal (0:00 to 3:00) of

CR5-2A (NTSC) / CR5-2A PS (PAL)

Adj. point:

RV504/DM-89(F-1)

Specification: NTSC: A = 714

7 mV (100

1 IRE)

PAL:

A = 700

7 mV

For PAL model only:

During play back the alignment tape in PLAY mode,

check the levels of R-Y and B-Y signals.

If the specification is not satisfied, adjust so that both

levels of R-Y and B-Y signals satisfy the specification.
