1. Setting the oscilloscope
Set the range to DC 1 V/div and 5µ/div.
2. Connecting the PC Interface
1) Fit the PC I/F in position and make sure the CON2, CON3 and CON4 connectors are all tight in place.
2) Connect the cable between the ANALOG OUTPUT (PC computer) and the DSUB connector (INPUT1 of the
proejctor).
3) Set the projector’s input selector to the INPUT1 position. Make sure the Dsub/BNC selector is at the Dsub
position.
4) Set the PC computer in the XGA mode (1024 x 768, 60 Hz, 32-step scale). Adjust the output amplitude to
700 mVp-p (terminated with 75 ohms) for the black-to-white portions.
5) Turn on the power.
3. Adjusting and checking the levels

3) Feed the 480P Y signal to the G(Y) input terminal. Keep the R (Pr) and B (Pb) terminals out of any input.
4) Adjust the B-BRIGHT data of DTV until the red signal’s black level becomes bitless.
5) Adjust the R-BRIGHT data of DTV until the blue signal’s black level becomes bitless.
