4.3.2.2 EE Y level
(1) Observe the V OUT waveform at the measuring point (D).
(2) Set the VCR to the EVR mode by transmitting the code (F1)
from the Jig RCU.
(3) Set the EVR address to (F2) by transmitting the code (F3)
from the Jig RCU.
(4) Transmit the code (F4) from the Jig RCU to adjust so that
the Y level of the V OUT waveform becomes the specified
value (G).
(5) Release the EVR mode of the VCR by transmitting the
code (F5) from the Jig RCU again. (When the EVR mode
is released, the adjusted data is memorized.)

4.3.2.3 EE composite burst level
(1) Observe the V OUT waveform at the measuring point (D).
(2) Set the VCR to the EVR mode by transmitting the code (F1)
from the Jig RCU.
(3) Set the EVR address to (F2) by transmitting the code (F3)
from the Jig RCU.
(4) Transmit the code (F4) from the Jig RCU to adjust so that
the burst level of the V OUT waveform becomes the spec-
ified value (G).
(5) Release the EVR mode of the VCR by transmitting the
code (F5) from the Jig RCU again. (When the EVR mode
is released, the adjusted data is memorized.)

4.3.2.4 EE R/G/B level
(1) Observe the R OUT waveform at the measuring point (D1).
(2) Set the VCR to the EVR mode by transmitting the code (F1)
from the Jig RCU.
(3) Set the EVR address to (F2) by transmitting the code (F3)
from the Jig RCU.
(4) Transmit the code (F4) from the Jig RCU to adjust so that
the R level of the R OUT waveform becomes the specified
value (G).
(5) Release the EVR mode of the VCR by transmitting the
code (F5) from the Jig RCU again. (When the EVR mode
is released, the adjusted data is memorized.)
(6) Observe the G OUT waveform at the measuring point (D2).
(7) Repeat steps (2) to (5) above.
(8) Observe the B OUT waveform at the measuring point (D3).
(9) Repeat steps (2) to (5) above.
