                Posted - 02/27/2022 : 22:44:58  Hi tech support,  Is there an updated FW version for GMC-500+ with these details: Model: GMC-500   Revision: Re 1.20 Serial #: 34XXXXXXXXXXX6
  B.t.w. Why Model is GMC-500 when sticker on device is GQ GMC-500+?
  thanks! |

                Posted - 03/05/2022 : 15:12:27  Hi EmpDev, I used this forum's direct message system to you!?  That does not work? True that I cannot find back myself what I sent.
  Replied to your email message anyway, thanks! |

                Posted - 03/04/2022 : 01:36:27  Hi EmfDev,
  Thanks for the support. Just sent to you the Serial #. Yes, it has 2 tubes. I think this device was from end of 2018 when we discussed the missing X-tal and the internal clock that didn't work because of that. |
