(3) The adjustments must be performed in the circumstance of

25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.

(4) The input voltage of the receiver be must kept 110V, 60Hz

when adjusting.

(5) The receiver must be operational for about 15 minutes

prior to the adjustments.

1) After receiving 100% white pattern, the receiver must be
