2007 super air 220.
Was surfing and perfect pass beeped a couple times. Now it is stuck on 6 mph and when I adjust speed it goes right back to 6. I tried to reset it but when it tells me to hit the up arrow for reset it won't do anything.
I would say low voltage too!!! I had the same problem this year with the display not working right. I put the batteries on a charger and the next day it work like normal. Perfect pass is very sensitive to voltage.
