(1) Color temperature should be adjusted under the condition in which the screen is the brightest,
thus the initial value for adjustment is set at its maximum.
(2) Adjustment is made by reducing brightness only. Reduce the brightest color for adjustment.
(3) Video color temperature & Adjustment number are the same, but addresses in the memory are
different, thus there’s no problem.
(4) When this adjustment item is done through MMC slot, Sniffer Jig must be inserted after the set is
switched to Sniffer Mode. (the PC would have trouble if this sequence is not kept.)
