I've lost the signal between my TN15 and the connected device
Power and charge
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, do not hesitate to get in touch with our service team by submitting a service ticket on the Kromek Customer Portal.
