Chapter 4 Settings — [PROJECTOR SETUP] menu134 - ENGLISHf Brightness and color are measured at the specified time. The dynamic contrast function does not operateduring measurement.13) Press as to select [CALIBRATION MESSAGE].14) Press qw to switch the item.f The items will switch each time you press the button.[ON] Displays messages during calibration.[OFF] Does not display messages during calibration.15) Press as to select [APPLY].16) Press the button.f When [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] is set to anything other than [OFF], thebrightness and white balance of light source at the time when the button is pressed is recordedas the standard brightness and white balance.f If the button is pressed when [LINK] is set from [GROUP A] to [GROUP D], the group name isdisplayed on the screens of projectors that have been set in the same group.LINK GROUP ANotef When [CONSTANT 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 beencompleted.f If the shutter function is enabled (shutter: closed) within approximately 10 minutes after the light source has turned on while [CONSTANTMODE] in [BRIGHTNESS CONTROL SETUP] is set to [AUTO] or [PC], brightness and color cannot be measured. Therefore, brightnessmay be corrected approximately two minutes after the shutter function is disabled (shutter: open).f Since the brightness and the color of the light source do not stabilize for approximately eight minutes after turning on the light source while[CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] is set to [AUTO] or [PC], the brightness and the color of the light source will beautomatically measured approximately eight minutes after the light source is turned on. A correction is made based on this measurementresult so that the brightness and the color will be the same as the standard brightness and the color when adjusted with the brightnesscontrol.f When [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] is set to [AUTO], and [LINK] is set to [OFF], the brightness will becorrected until it reaches the value set in [MAX LIGHT OUTPUT LEVEL].f The variation in brightness may increase due to dust accumulating on the lens, screen, or inside the projector, depending on the installationenvironment of the projector.f When the variation in brightness has increased due to aging of the light source, or when you replaced the light source, readjust thebrightness control.f When the projector is used continuously for more than 24 hours, set the [CALIBRATION TIME] in [BRIGHTNESS CONTROL SETUP]. If it isnot set, correction will not be performed automatically.f The brightness control function and the dynamic contrast function will operate simultaneously, but the dynamic contrast function will notoperate while measuring the brightness and the color.f The [CALIBRATION TIME] setting will be reflected when you enter the time.f The [CALIBRATION MESSAGE] setting will be reflected at the time when the item is switched using qw.Displaying [BRIGHTNESS CONTROL STATUS]Display the brightness control status.1) Press as to select [BRIGHTNESS CONTROL].2) Press the button.f The [BRIGHTNESS CONTROL] screen is displayed.3) Press as to select [BRIGHTNESS CONTROL STATUS].4) Press the button.f The [BRIGHTNESS CONTROL STATUS] screen is displayed.
