 fWhen set to [ECO], network functions are not available during standby . Also, some RS - 232C commands are not available. When set to 
[NORMAL], network functions are available during standby.
 f If set to [ECO], there may be a delay in displaying when the power is tu\
rned on compared to when set to [NORMAL].
[BRIGHTNESS CONTROL]
The projector has a built-in brightness sensor which measures the bright\
ness of the light source and has a function which corrects the 
brightness of the screen according to the change in the brightness of th\
e light source.
The light source deteriorates over time. By using this function, you can\
 reduce the change in overall brightness or keep it uniform by 
suppressing the variation in brightness when displaying multiple screens\
 using multiple projectors.
Note
 fIf [DYNAMIC] is selected in the [PICTURE] menu  → [PICTURE MODE], [BRIGHTNESS CONTROL] cannot be selected.
Setting [BRIGHTNESS CONTROL GAIN]
Adjust the brightness when displaying multiple screens using multiple pr\
ojectors.
1) Press as to select [BRIGHTNESS CONTROL].
2)  
Press the  button.

Press the q button. The screen becomes darker. The maximum amount of 
correction is increased.
Note
 f
When using only one projector , the value obtained by subtracting the value of the [BRIGHTNESS CONTROL\
 GAIN] from 100   % is the 
maximum amount of brightness correction. Brightness cannot be corrected \
through brightness control since the maximum amount of 
correction becomes 0
  % when [BRIGHTNESS CONTROL GAIN] is at 100   %.
 fBrightness is not stable for 15 minutes after the light source lights up\
. Make adjustments at least 15 minutes after starting projection. fThe result of [BRIGHTNESS CONTROL

 GAIN] adjustments is reflected on all image signals, internal test patterns, and on-screen menus.

measured 15 minutes after the light source lights up, and correction is \
performed so that the screen brightness will be the same as the 
standard brightness when the brightness control is adjusted. Brightness \
is not measured since the light source brightness is not stable for 
approximately 15 minutes after the light source lights up.
 f When [MODE] of [BRIGHTNESS CONTROL

 SETUP] is running in [AUTO] and [LINK] is [OFF], the brightness will be corrected until it 
reaches the maximum amount of correction.
