Note: RGB Gain/Bias adjustment relate to temperature, therefore adjust-
ment within 5 minutes after supplied power.
[R Gain Adjustment]
Condition:
Input signal SVGA 60 Hz: RGB 0.7 Vp-p, 16 Step
Measurement point MA-324 (H) board CN206 pin 1
Measuring equipment Oscilloscope
Adjustment page F
Adjustment address 68
Specification value 2.7 ± 0.1 Vp-p
Connection:
Adjustment Procedure:
(1) Connect an oscilloscope to the CN206 pin 1 on the MA-
324 (H) board.
(2) Set (or confirm) data: 01 to page: 0, address: 01.
(Cancel F page protect)
(3) On page: F, address: 68, change data with the PLAY and
STOP buttons and press the PAUSE button to write data so
that F level of waveform on the oscilloscope satisfies the
specification value.
Adjustment and Connection Location: MA-324 (H) board

Adjustment address 6B
Specification value 8.4 ± 0.1 Vp-p
Connection:
Adjustment Procedure:
(1) Connect an oscilloscope to the CN206 pin 1 on the MA-
324 (H) board.
(2) Set (or confirm) data: 01 to page: 0, address: 01.
(Cancel F page protect)
(3) On page: F, address: 6B, change data with the PLAY and
STOP buttons and press the PAUSE button to write data so
that the G level of waveform on the oscilloscope satisfies
the specification value.
