Tartarus V2 types number 3 continuously

Hey guys,



I'm facing issue with my Razer Tartarus V2 Mecha-Membrane Gaming Keypad. The problem is that i randomly hear like a usb disconnect sound and then on the screen i see number "3" continuously till i hit any of the keypads on the tartarus v2.



This is only on the Tartarus V2 and if i disconnect it and check only with the blackwidow elite keyboard and deathadder elite mouse there's no issue.



Can somebody please help, thanks in advance.
