To Be Honest with you i think i have been sold the wrong item is says GMC 500 + it has 2 tubes but no option to switch between tubes
Serial number is / 34193337333813
I Purchased via Amazon so i am now thinking of returning it as i dont believe i have been sold the correct item

Tube selection is on Main Menu -> Init Setup -> Tube Settings -> Tube Selection.

Can you please email me the serial number under Main Menu -> About -> Serial number so I can check? And also please check on the back there are two windows to see the tubes. One is transparent and one is black. Do you see both?

That is weird. What did you mean "It only say about tube"?

Did you see the Tube Settings Menu under Init Setup? Can you list the options under it? Thanks.

Indeed there is no tube selection. I already made the firmware because I suspect that there is wrong firmware downloaded but just want to make sure the serial number on my part is correct. Can you please double check the Main Menu -> About -> Model? and also Main Menu -> About -> Revision? Thank you so much!

Before I send you the firmware, can you try to do a factory reset?

Best Regards Simon.

Hello and Thank you for All of your help in the past. I Have found out today that the counter that was sold to me is a GMC-500 and not the plus version the seller i purchased from on Amazon must have tampered with the unit as i see the 500 does not have 2 tubes yet this unit has 2 tubes installed it was sold as a 500+ unit but i have done another factory reset and it now says it is a 500 not the plus version so the seller must have put another tube in the unit and sold it to me as a GMC-500+ When in fact it is a 500 just with an extra tube that probably does not work
