1)

Press the S5001 key to call the process mode.

2)

Execute S1 on the SSS menu. (The S1 is used to initialize the PC board alone. Do not execute S2 because
otherwise all the adjusted data but the PC board will be initialized.)

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

µ

s/div.

Feed the XGA 1024x768 60Hz gradation waveform signal.

1)

Press the S5001 key to call the process mode.

2)

Adjust the SH-PHASE setting on the "OUTPUT 3" menu until the "OUTPUT 3" characters are not blurry any
longer.

3)

Connect a oscilloscope to TP2. Adjust the BRIGHT setting of "OUTPUT 2" to have the black level of the signal
at 1.7V.

4)

Adjust the ROS setting on the A/D menu until the voltage at the positive pole of C64 or pin (2) of IC11 becomes
1.7V.

5)

Adjust the GOS setting on the A/D menu until the voltage at the positive pole of C57 or pin (2) of IC10 becomes
1.7V.

6)

Adjust the BOS setting on the A/D menu until the voltage at the positive pole of C50 or pin (2) of IC9 becomes
1.7V.

7)

Make sure the GAIN setting on the A/D menu is 163.

8)

Connect the oscilloscope to TP1. Adjust the R-D setting on the A/D menu until the white top level of the signal
becomes 3.6V. (Make sure that both the black and white graduations are visible clearly.)

9)

Connect the oscilloscope to TP3. Adjust the B-D setting on the A/D menu until the white top level of the signal
becomes 3.6V. (Make sure that both the black and white graduations are visible clearly.)

10) Connect the oscilloscope to TP2. Adjust the G-D setting on the A/D menu until the white top level of the signal

becomes 3.6V. (Make sure that both the black and white graduations are visible clearly.)

11) Add 10 points to the BRIGHT setting on the OUTPUT2 menu.
12) Press the S5001 key to exit from the process mode.
