After Auto-Setup only some or
no DVB channels are found. ≥Check to ensure your area is covered by DVB transmissions.
≥Check that the aerial and antenna cable are designed for DVB.
For your safety, the aerial and cable should be inspected/installed by a licensed installer that
should comply with Australian Standard AS1417.1.
If you live within 5-10 km of DVB transmission towers, a combined VHF/UHF aerial should be
adequate. Outside this area, separate VHF and UHF aerials provide superior reception
performance.
≥If you live in a unit or apartment, check to ensure the Master Antenna TV (MATV) system is
designed for DVB-T reception. Please consult your body corporate.

≥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 antenna wall socket to minimise impulse
noise pickup. If problem persists consult your local TV aerial installer.
≥Check aerial connection.
≥Adjust the aerial reception with “DVB Manual Tuning” in the Setup menu.

with wind in “leafy” locations may cause pictures to break up and audio to mute or distort
momentarily.
≥Impulse noise interference from an infrequently used electrical appliance, or a passing
vehicle or lawn mower with a “noisy” ignition system.
