Q

The setting will change as follows each time 

 

z

◄► is pressed.

Brightness is corrected using the 
brightness sensor of one of the 
projectors, without linking with other 
projectors.
A smaller [BRIGHTNESS CONTROL 
GAIN] value means the constant 
brightness can be maintained for longer.

Brightness is corrected using brightness 
sensors of multiple projectors linked 
with each other.
Up to 4 groups from A to D can be set 
within the same sub-network using 
the network function that links multiple 
projectors.
Up to 8 projectors can be registered in 
1 group and linked with each other.

The selected [MODE] and [LINK] are activated, 

 

z

then the [BRIGHTNESS CONTROL STATUS] 
screen will be displayed.
If <ENTER> button is pressed while [MODE] of 

 

z

the brightness control is not switched to [OFF], 
the lamp power at the time is saved as the 
reference power.
If <ENTER> button is pressed while [LINK] is 

 

z

[GROUP A - D], the group name is displayed on 
the screens of the projectors that are set in the 
same group.

When setting [MODE] of the brightness control to [AUTO] 

 

z

or [PC], execute brightness control with the shutter open 
for at least 2 minutes.
If the shutter is closed within about 10 minutes after 

 

z

the lamp is turned on while the brightness control is set 
to [MODE], [AUTO], or [PC], the brightness cannot be 
measured. In this case, the brightness may be corrected 
about 2 minutes after the shutter is opened.
While [MODE] of the brightness control is set to [AUTO] 

 

z

or [PC], the [DYNAMIC IRIS] function is kept [OFF (No 
correction)].
While [MODE] of the brightness control is set to [AUTO] 

 

z

or [PC], the [LAMP POWER] is fixed to [HIGH] or [LOW]. 
When changing the lamp power, return [MODE] of the 
brightness control to [OFF], then change the lamp power 
and adjust the brightness control again.
While [MODE] of the brightness control is set to [AUTO] 

 

z

or [PC], the lamp power is measured automatically 
about 8 minutes after the lamp is turned on and then 
corrected so that the screen brightness will be the same 
as the reference brightness when the brightness control 
is executed. The lamp power is not measured for about 
8 minutes after the lamp is turned on as it does not 
stabilize within this period.
While [MODE] of the brightness control is set to [AUTO], 

 

z

if the lamp is kept on for more than 25 hours, the 
brightness is corrected automatically every 25 hours.
While [LAMP SELECT] is set to [DUAL] and [MODE] 

 

z

is set to [AUTO], if the lamp goes off, the brightness is 
corrected as much as possible about 1 minute after.
While [MODE] of the brightness control is set to [AUTO] 

 

z

and [LINK] is set to [OFF], the brightness is corrected 
until the maximum quantity of correction is achieved.
The brightness may be dispersed largely because of dust 

 

z

sticking to the lens, screen, or inside of the projector, 
depending on the environment in which the projector has 
been installed.
If the brightness fluctuates significantly because of aging 

 

z

of the lamp or if the lamp has been replaced, re-adjust 
the brightness control.

This function displays the status of the brightness 
control.

The [BRIGHTNESS CONTROL STATUS]

screen will be displayed.
