3) Make sure that the program version "VER. XXX" on the SPECIAL menu is the latest one.
2. Level adjustments
2-1. Setting the oscilloscope
Set the oscilloscope's range to DC1V/div and 5µ S/div.
2-2. Connecting the PC interface
1) Connect the specified cable between ANALOG OUTPUT (on the signal generator) and DSUB connector
(INPUT1 on the projector).
2) Set the projector's input selector to INPUT1.
3) Set the signal generator to XGA mode (1024x768, 60Hz, 32-step gradation). Also adjust the output
amplitude (between black and white) to 700 mVp-p (terminated with a 75-ohm impedance).
4) Turn on the power.
2-3. Adjusting items
