Pimax Crystal Super IPD system jammed

[MichaelJWP15]

Having been trying the system for a few days and having real trouble with the IPD, I realised the buzzing sound kept going on and the numbers were not changing. I read a few links which mentioned this issue.. anyone know about it or have a way of fixing it?

Otherwise I may have to return it, I have raised a ticket though to see what Pimax say.
