Color Temperature Sensor
Protection
If no operations are performed for approximately 10
minutes from the moment color temperature
adjustment processing ends, power to the projector
shuts OFF automatically in order to protect the color
temperature sensor. If power is shut OFF to protect
the color temperature sensor, do the following.
• If the WARNING indicator does not light
When color temperature adjustment ends
successfully and the sensor protection feature
trips, the projector goes on standby. As usual,
activate power by pressing either the ON
button on the remote control or the
/ I
button on the projector.
• If the WARNING indicator lights
If color temperature adjustment does not end
successfully and the sensor protection feature
trips, the projector's WARNING and STANDBY
indicators light simultaneously to indicate the
error mode. Unplug the power cable and then
plug it back in. Then, press either the ON
button on the remote control or the
/ I
button on the projector to reactivate power.

Before pressing the ENTER button, turn the
color temperature sensor over on its dark side
as shown in the below figure, to prevent
outside light from penetrating to the sensor’s
condenser.
4. Press the ENTER button. The below message
appears on the screen for a few seconds as
the sensor is being calibrated.
5. Position the lamp so that its light passes
through the center of the lens. This is
necessary in order to calibrate color
temperature correctly. First, turn the lens shift
knob all the way to the left so that the lens
lowers to the lowest position. Then, turn it five
and a half turns to the right to raise the lens.
In this position, the light of the lamp passes
almost through the center of the lens.
Note:
Color temperature cannot be correctly
calibrated unless the lens is properly
positioned.
