Hello everybody. I have a problem with my old Humphrey 720 perimeter. When I turn on the perimeter it shows me the error message "System startup state 15".
I've tried all the recommended actions (Dim room lights and retry, perform shutter and wedge calibration) but nothing works. Any ideas?

Yes, it often does Just clean the sensor mirror and then do calibration
I have done a lot of repairs on these

Hello! I suppose you mean to calibrate the brightness detector. But for that don't I need a brightness detector alignmet target to use?
