      2. SIGMA 25/50

      I've lost the signal between my SIGMA 25/50 and the connected device

      Power and cables

      First, check the power source (laptop or computer USB slot).

      Then, check to see if the cable is working.

      Change the power source if neither of these work.

      If there is still no signal, don’t hesitate to by get in touch with our service team by submitting a service ticket on the Kromek Customer Portal.
