Color Temperature Adjustment

After replacing the lamp or in other cases where the lighting changes, color temperature can be adjusted using the color temperature sensor. In the adjustment procedure, you must first initialize the sensor itself before adjusting color temperature. It takes about 10 minutes from when the power to the projector is activated for the lamp’s brightness to stabilize. Wait for lamp brightness to stabilize before adjusting color temperature.

1.Connect the cable of the color temperature sensor to the RS-232C port.

2.Press the MENU button and select “Color Temp. Calibration” from the MENU screen. Press the 2 button. The below message appears on the screen.

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.

6.Fit the color temperature sensor onto the lens and press the ENTER button. Color temperature adjustment starts and the projector’s WARNING and STANDBY indicators begin flashing simultaneously.

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.
