Vertical Card Compass Interference?

It is highly possible that the S100 (or other speakers) will interfere with the PAI compass.

I'm trying to figure out that gremlin right now. PAI recommended shielding the speakers which I am working on.

YMMV -

If the interfering magnetic field is strong enough, the correction adjustments in the compass won't be able to compensate for the stray field. What you then do is set the correction adjustments on the compass back to neutral. Then use a separate neodymium magnet to correct the compass error instead of the compass built in magnets.

Start to swing the compass as you would normally do, but move the strong neodymium magnet around near the front of the panel. Rotate it and change the distance as required to determine what location will best correct the compass error. When you have it as good as possible, tape the magnet in position on the backside of the panel.

Repeat the compass swinging procedure using the compass built in correction magnets. This should get you acceptably close. Permanently attach additional correction magnet in place.
