CHAPTER 4: Operation 4.1 Indicators Most of the Converter’s indicators are mounted in, and function in concert with, its front-panel pushbuttons; these indicators are described in the next section. There are also two independent LEDs mounted in the front panel: POWER: This indicator lights when your Converter is ON (receiving DC power through its external power supply). If this light is glowing dimly or not at all, there might be something wrong with the power supply. See Chapter 6. INPUT: This

PROVIDEO CONVERTER AND VIDEO CONVERTER II ANTI-FLICKER BUTTON: When this button has not been pressed, the Converter sends images using fully interlaced composite, S-Video, and RGBS video signals.

When you press this button once, its green light will flash once and stay lit, indicating that “level 1” of

CHAPTER 5: What to Expect from Converted Computer Images 5. What to Expect from Converted Computer Images We have included this section to give you some insight into what you can and should expect computer images to look like once they are converted to standard video.

PROVIDEO CONVERTER AND VIDEO CONVERTER II • Sometimes graphics look so impressive on a computer monitor that users assume that the process of conversion to TV can’t possibly make the graphics look bad. However, what TVs will actually show, especially if they are displaying a video signal that was “beat up” by a VCR recording, can be ugly.
