Sirs Navigator compass calibration instructions

Somehow, the calibration instruction sheet for the Sirs compass has disappeared from the internet, and from the company site. I finally did find a backup file and I'm posting it here so that others here who need to perform their annual calibration have access to this information.

By the way, the little plastic adjustment tool (has a triangular hole) is sold by Aircraft Spruce as an "installation kit" for $60, or $35 for just the plastic tool! https://www.aircraftspruce.com/catalog/inpages/NAVImounting4.php

Great compass, but what is happening to the company...?
