April 7, 2025

I am currently installing 4 modules, each with 2 of the Raytek MI3 units. 7 of the units arrived with the normal display (Bottom Unit in photo), but 1 has only a full white block in the display. Is this indicative of a failed unit, or would this require external adjustments. These units always work when received, so I am unfamiliar with the required troubleshooting.
