**Caution **
Color Temperature : COOL, Medium, Warm.
One of R Gain/G Gain/ B Gain should be kept on 0xC0, and
adjust other two lower than C0.
(when R/G/B Gain are all C0, it is the FULL Dynamic Range of
Module)
4.2. Manual W/B process using adj. R/C
• After enter Service Mode by pushing “ADJ” key,
• Enter White Balance by pushing “
G
”key at “7.White Balance”
* After done all adjustments, Press “In-start” button and compare
