unless you use an approved installer the warranty might be invalid.
That is industry standard, and understandably, too. It is not hard to destroy any piece of electronics, least of all if it contains a transmitter. Reversing the supply voltage and transmitting with no antenna connected are guaranteed recipes, to name but those two.
As I understand things, Trig leave their dealers/resellers some leeway in judging on this kind of matter. Good on them!
