≥Check that the aerial and dish cable are designed for DVB.
≥Interference (known as impulse noise) from household appliances such as light switches,
fridges etc. may cause picture break up and/or audio distortion. Use a high quality quad
shielded coaxial cable fly lead between this unit and dish wall socket to minimise impulse
noise pickup. If problem persists consult your local TV aerial installer.

reception. There must not be any hindrances in the way which could impair reception, e.g.
twigs, leaves, snow.
