- If “cool” mode 

Let B-Gain to 192 and R, G, B-Cut to 64 and then
control R, G gain adjustment High Light adjustment. 

- If “Medium” and “Warm” mode 

Let R-Gain to 192 and R, G, B-Cut to 64 and then
control G, B gain adjustment High Light adjustment. 

- All of the three mode 

Let R-Gain to 192 and R, G, B-Cut to 64 and then
control G, B gain adjustment High Light adjustment. 

- With volume button (+/-) you can adjust.  
- After all adjustment finished, with Enter (
