ing Section 9-33-1.
When there remains the RPN which cannot be concealed
even after completion of the adjustment shown in Section

Adjustment Procedures
n
The points adjacent to the already corrected RPN in the up,
down, right, and left directions cannot be corrected.
1. Select the channel (R, G, or B) to be corrected.
ITEM : OUTPUT SELECT → R, G, B
2. Adjust the values of H and V so that the center of the
cross cursor is aligned just over the RPN.
ITEM : RPN CURSOR → ON
ITEM : CURSOR H POS.
ITEM : CURSOR V POS.
n
One full rotation of the rotary encoder is equivalent to
the movement by one-pixel. Since the cursor occupies
the area equivalent to two pixels, the cursor moves
with two rotations of the rotary encoder.
3. Press the rotary encoder to record the RPN data
(concealed value).
ITEM: RECORD RPN → EXEC
4. "RECORD DATA OK? YES → NO" is displayed.
After confirming that the RPN is corrected, rotate the
rotary encoder until "YES" blinks.
5. Press the rotary encoder. "COMPLETE!" is displayed,
and concealment will be performed.
n
Make sure that RPN is corrected before executing the
RPN concealment.
6. If the RPN concealment is going to be executed for
another RPN, repeat steps 2 to 5.

When there exists an RPN that cannot be corrected
with this adjustment, follow the flowchart of the
