1. Did you connect your antenna as illustrated pages 6 and 7?
If you have a pay TV box, VCR or other device connected then the TV must be connected to the
antenna using a splitter.
2. Is the antenna wall socket in good condition?
For optimum and reliable contact performance, the antenna wall connector should be an 'F' (screw)
type connector.
3. Are you using a quality antenna fly lead between antenna wall socket and HD-STB?
The use of RG6 or RG59 Quad Shield 75 ohm coaxial cable fly leads with metal 'F' connectors
provides a secure, reliable connection that also greatly reduces impulse noise pickup. Low cost
antenna fly leads with right-angled plastic moulded connectors are a common cause of poor reception
and impulse noise pickup.
Digital TV or some channels (services) may not have yet commenced in your area.
There are some towns and regions in Australia that cannot yet receive digital television. In some towns and
regions not all broadcasters have commenced their digital services. You can check the digital coverage for
your area at the Reception Locator on the DBA website (www.dba.org.au/reception).

What to do
Check that the mains cable is plugged in to
the power socket.
Check the cable connections and other
equipment connected to your TV.
Change the batteries.
Switch off the light.
Aim the remote control at the TV.
Check the antenna cable connections or if an
upgrade to your antenna is required to
receive digital TV signals in this area.
If 'signal quality' or 'signal strength' bar is not
green, it indicates that the digital receiver is
not receiving an adequate signal. The
antenna and/or cable system needs to be
checked (maybe replaced) by an antenna
installer.
Check that the antenna is suitable to receive
all RF channels. Try doing channel tuning
installation again.
