How do you use a degaussing coil?

How do you use a degaussing coil for the arcade screen? Particularly this one they sell at Happ:

Thanks.

You hold it like you’re going to toss it, push the button to activate it, and move it around the edge of the monitor. Pretty much anywhere you see magnetic distortion.

what if a degaussing coil doesn’t fix the messed up image?

well, I think they usually do. By the way, if you have a computer or TV monitor, it should have a built in degaussing capabaliity.

If it doesn’t, then your monitor is screwed. At evo2k2, we had a problem with one of the monitors and the coil did not work to fix the problem.

Hold in in front of the screen, then move it around in a circular motion while moving it away from the screen…
