• PIN PHASE (RV309)
Adjust trapezoidal strain with RV309 (PIN PHASE)
on DA (DC-l) board.
• SIDE PIN (RV310)
Adjust pin cushion strain about right and Iwft
with RV3l0 (SIDE PIN) on DA (DC-1) board.
NOTE: In case of pin cushion strain of right and
left rate is differ. correct them with RV311
(PIN BAL) too.
• PIN BAL (RV31 1)
Adjust PIN balance strain with RV3ll (PIN
SAL) on DA (DC-l) board.
• PIN UP (RV313)
Adjust upper PIN strain with RV3l3 (PIN UP)
on DA (DC-l) board.
