1) Press SW2002 to enter the process mode.
2) Execute the S1 command on the SSS menu. (The S1 command initializes the PC board alone. Do not

execute the S2 command because otherwise the adjustment data other than the PC board will be initialized.)

3) Make sure that the program version VER.XXX on the SPECIAL menu is the latest one.

2. Adjusting the levels
2.1 Setting the oscilloscope

Set the oscilloscope range to DC 1V/div. and 5 

µ

sec/div.

2.2 Connecting the PC interface

1) Connect the analog output (signal generator) and the DVI-1 connector (INPUT 5 of the projector) with the

cable (DSUB-DVI)
Set the INPUT SELECT of the projector to INPUT 5 (select the analog RGB on the menu.)

2) Set the signal generator to the XGA mode (1024x768, 60 Hz, 32 tones). Adjust the output amplitude to 700

mVp-p between the black and white levels (terminated with a 75-ohm impedance).

3) Turn on the power.

2.3 Adjusting and checking the levels

1) Press SW2002 to enter the process mode.
2) Select the AUTO adjustment mode.

2.4 Adjusting the DTV

1) Feed the signal to the INPUT1’s RCA input terminal.
2) Set the signal generator to the 1080i 60-Hz mode with white signal. Adjust the output amplitude to 700 mVp-

p between the black and white levels.

3) Connect the specified cable between the analog output (signal generator) and the RCA connector (INPUT1

of the projector).

4) Make the G-BRIGHT setting the same as the G-BRIGHT setting of Group A/D.
5) Adjust the CB-OFFSET setting of Group DTV to 20.
6) Adjust the CR-OFFSET setting of Group DTV to 20.
7) Finally press SW2002 to exit from the process mode.
