First Degree Fitness QB8D90 User manual

Hello! I have reviewed the document provided, which is a user guide for the speed sensor troubleshooting and replacement for First Degree Fitness rowing machines, including the Pacific Challenge AR, Newport Challenge AR, and Trident Challenge AR models. The document provides detailed step-by-step instructions for checking issues, removing, and reinstalling the speed sensor. I am ready to answer your questions about these instructions or the sensor itself.
What should the gap be between the sensor and the magnetic ring?

How many magnets should be present in the magnetic ring?

How far inside the hole should the internal sensor be?

flush (no need to remove the ring)

a few millimeters inside the hole
