(2) The adjustment must be performed under the correct
sequence. But, it can be changed within the error
boundary of performance, considering the mass
productivity.
(3) The adjustment must be performed in the circumstance of
25 °C ± 5 °C of temperature and 65 % ± 10 % of relative
humidity.
(4) For the adjustment, the receptor’s input voltage shall be
maintained at 220 V, 60 Hz.
(5) The set must be on for 5 minutes prior to any adjustment.
After receiving possible 100 % White Pattern, it is ready for
