7.Não posicione o receptor em nichos da parede ou perto de chapas de metal ou de arames. Redes de arame constituem um grande obstáculo.

8.Não coloque as antenas em posição paralela a superfícies metálicas.

9.Evite racks de luz e tubos fluorescentes. Starters e dimmers emitem radiação RF.

10.Evite dispositivos de efeito digitais e computadores pessoais. Estes também emitem radiação RF.

10. Limpeza

Para limpar a superfície do transmissor use um pano macio mol- hado com álcool etílico (industrial) ou álcool símples.
