1) Using the remote control, set the LCD TV to adjustment mode.
2) Measure Max brightness (Lmax).
3) Calculate min. brightness (Lmin)=Lmax/1000.
4) Measure Point 2 brightness (Lhigh).
5) Set the reference value R,G,B of Point 2 (R2)=3664 x (229/P2) 
where P2=255 x [(Lhigh-Lmin)/(Lmax-Lmin)]1/2.2
6) Set the specified gradation for point 2, fix the most faint colour to get reference 
value, adjust others 2 colour to minus adjustment for reference value of point 2.
7) Measure Point 1 brightness (Llow).
8) Set the reference value R,G,B of Point 1 (Ref.1)=608 x (38/P1) 
where P1=255 x [(Llow-Lmin)/(Lmax-Lmin)]1/2.2
9) Set the specified gradation for point 1. Set G of point 1 to the default value [(Ref.1 x 
G value of point 2/Ref.2), with fractions rounded] and adjust RB to the reference 
value of point 1.
10)Set the G of point Max. to the default value (4080 x G value of point 2/Ref.2). Set    
the R,B Max. value [Gmax-G value of point 2 + (R,B value of pint 2)]. 
11)Adjusted value is writing at [command] MSET0003.
12)Shut down the AC power.
