[Light Output] - Panasonic PT-RW620 Operating Instructions Manual

f If the <ENTER> button is pressed when [LINK] is set from [GROUP A] to [GROUP D], the group name is
displayed on the screens of projectors that have been set in the same group.
15) When the confirmation screen is displayed, press qw to select [OK], and press the <ENTER> button.
Note
f When the projector operates with [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] set to [AUTO] or [PC], keep the shutter
function disabled (shutter: open) for at least two minutes, since the brightness sensor calibration is performed after the [BRIGHTNESS
CONTROL SETUP] setting has been completed.
f If the shutter function is enabled (shutter: closed) within approximately 10 minutes after the light source has turned on while [CONSTANT
MODE] in [BRIGHTNESS CONTROL SETUP] is set to [AUTO] or [PC], brightness and color cannot be measured. Therefore, brightness
may 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 when
the projector operates with [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] set to [AUTO] or [PC], the brightness and the color
of the light source will be automatically measured approximately eight minutes after the light source is turned on. A correction is made based
on this measurement result so that the brightness and the color will be the same as the standard brightness and color when adjusted with
the brightness control.
f When the projector operates with [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] set to [AUTO] or [PC], the items of
[OPERATING MODE] and [LIGHT OUTPUT] cannot be changed.
f When the projector operates with [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] set to [AUTO], and [LINK] set to [OFF], the
brightness will be corrected 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 installation
environment 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 the
brightness control.
f When the projector is used continuously for more than 24 hours, set the [CALIBRATION TIME] in [BRIGHTNESS CONTROL SETUP]. If it is
not 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 not
operate 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 when items are switched using qw.

[LIGHT OUTPUT]

Adjust the brightness of light source.
The setting is reflected when it is already set with "Initial setting (operation setting)" (x page 58) in the [INITIAL
SETTING] screen or with the [PROJECTOR SETUP] menu → [OPERATION SETTING]. The [LIGHT OUTPUT]
setting is synchronized with the [PROJECTOR SETUP] menu → [OPERATION SETTING] → [LIGHT OUTPUT].
The most recent setting is reflected in both items.
1) Press as to select [LIGHT OUTPUT].
2) Press qw to adjust
Operation
Press w.
Press q.
Note
f [LIGHT OUTPUT] can be adjusted individually for each setting item of [OPERATING MODE].
f In such a case when configuring multiple screens with multiple projectors, uniformity of brightness between multiple screens can be
obtained by adjusting [LIGHT OUTPUT].
