Adjusting procedure
1. Observe the 0% window pattern chromaticity on
CA100.
2. Starting with a bit dropout screen, vary the B-
Bright setting until the bright blue "y" setting turns
toward the black tone and stays there. Now raise
the setting by one point and adjust to the point
where the first bit dropout is encountered (the
setting changes over 5/1000).
3. Observe the 91% G signal chromaticity on CA100.
4. Starting with a bit dropout screen, vary the B-
Contrast setting until the bright blue "y" setting
turns toward the black tone and stays there. Now
raise the setting by one point and adjust to the
point where the first bit dropout is encountered
(the setting changes over 5/1000).
1. Check the fixed value.
Contrast: 5
Bright: 55
1. Observe the 0%black window pattern chroma-
ticity on CA100.
2. Starting with a bit dropout screen, vary the Bright
setting until the bright red "x" setting turns to-
ward the black tone and stays there. Now raise
the setting by one point and adjust to the point
where the first bit dropout is encountered (the
setting changes over 5/1000).
3. Observe the 100% W window pattern chromatic-
ity on CA100.
4. Starting with a bit dropout screen, vary the Con-
trast setting until the bright red "x" setting turns
toward the black tone and stays there. Now raise
the setting by one point and adjust to the point
where the first bit dropout is encountered (the
setting changes over 5/1000).
1. Observe the 0%black window pattern chroma-
ticity on CA100.
2. Starting with a bit dropout screen, vary the Bright
setting until the bright green "y" setting turns
toward the black tone and stays there. Now raise
the setting by one point and adjust to the point
where the first bit dropout is encountered (the
setting changes over 5/1000).
3. Observe the 100% W window pattern chromatic-
ity on CA100.
4. Starting with a bit dropout screen, vary the Con-
trast setting until the bright green "y" setting turns
toward the black tone and stays there. Now raise
