Međutim, ne postoji garancija da se smetnje neće pojaviti u određenoj instalaciji. Ako ova oprema uzrokuje štetne smetnje radio ili televizijskom prijemu, što se može utvrditi isključivanjem i uključivanjem opreme, korisnik se ohrabruje da pokuša ispraviti smetnje jednom od sljedećih mjera:

• Preusmjerite ili premjestite prijemnu antenu.
• Povećajte razmak između opreme i prijemnika.
• Povežite opremu u utičnicu na strujnom kolu različitom od onog na koji je priključen prijemnik.
