11) Press qw to select "hour" or "minute", and press as or the number (<0> - <9>) buttons to set a
time.
f Selecting "hour" allows setting of only the hour in increments of one hour, and selecting "minute" allows
setting of only the minute in increments of one minute between 00 and 59.
f If you do not specify the time, select [OFF] between 23 and 00 o'clock or between 59 and 00 minutes.
12) Press the <ENTER> button.
f [CALIBRATION TIME] is set.
f The brightness is measured at the specified time.

RELAY] setting is [OFF]. When [CALIBRATION MESSAGE] is set to [ON], a calibration running message is
displayed which will automatically disappear 30 seconds after calibration completes.
f If the <ENTER> button is pressed with [MODE] in [BRIGHTNESS CONTROL SETUP] set to other
than [OFF], the brightness of the lamp at the time the button was pressed is recorded as the standard
brightness.
f If the <ENTER> button is pressed while [LINK] is set between [GROUP A] and [GROUP D], the group name
is displayed on the screens of projectors that have been set in the same group.
Note
f When [MODE] in [BRIGHTNESS CONTROL SETUP] is set to [AUTO] or [PC], keep the shutter function disabled (shutter: open) for at least
two minutes to perform the brightness sensor calibration after the [BRIGHTNESS CONTROL SETUP] setting has been completed.
f If the shutter function is enabled (shutter: closed) within approx. 10 minutes after the lamp has turned on while [MODE] in [BRIGHTNESS
CONTROL SETUP] is set to [AUTO] or [PC], brightness cannot be measured. Therefore, brightness may be corrected approx. two minutes
after the shutter function is disabled (shutter: open).
f When [MODE] in [BRIGHTNESS CONTROL SETUP] is set to [AUTO] or [PC], the lamp brightness is automatically measured eight minutes
after the lamp is turned on, and correction is performed so that the screen brightness will be the same as the standard brightness when the
brightness control is adjusted. Lamp brightness cannot be measured during the eight minutes after it is turned on because it is not steady.
f If a lamp turns off or lamp relay is performed while [MODE] in [BRIGHTNESS CONTROL SETUP] is set to [AUTO] and when the
[PROJECTOR SETUP] menu → [LAMP SELECT] is set to [DUAL], brightness is corrected to the possible extent one minute later.
f When the projector is operating with [MODE] in [BRIGHTNESS CONTROL SETUP] set to [AUTO] and [LINK] set to [OFF], brightness
correction is corrected until it reaches the maximum correction value.
f The variation in brightness may increase due to dust accumulating on the lens, screen, or inside the projector, depending on the installation
environment of the projector.
f Adjust brightness control again when lamp degradation causes increased variation in brightness or a lamp is replaced.
Chapter 4 Settings — [PROJECTOR SETUP] menu
Performs corrections by the brightness sensor on one projector without synchronizing with the other
projectors.
The duration that the constant brightness is kept will become longer by setting the value of
[BRIGHTNESS CONTROL GAIN] smaller.
Synchronizes corrections in multiple projectors by the brightness sensor.
You can set up to four groups (A to D) within the same subnet by using the network function.
You can also register and synchronize up to eight projectors in one group.
Messages are displayed during calibration.
Messages are not displayed during calibration.
