Digital broadcasts cannot be 
received.

 Check the connections.

 Digital broadcast may not have started in your region yet.
 The aerial may not be pointing in the direction of the TV station, or the 

direction of the aerial may have changed due to strong winds or vibration. 
If problem persists consult your local TV aerial installer.

TV reception worsens after 
connecting the unit.

 This can occur because the signals are being divided between the unit and 

other equipment. It can be solved by using a signal booster, available from 
electronics retailers.

−

After DVB 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.

Use the included RF coaxial cable shown in STEP 2, Basic Connection.
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.

Picture regularly breaks up on 
some channels, “No Signal” 
message is displayed.

 Check “Signal Condition”. If “Signal Quality” or “Signal Strength” are 

displayed in red or constantly changing, check aerial. If problem persists 
consult your local TV aerial installer.

 Check that the aerial and antenna cable are designed for DVB.

Use the included RF coaxial cable shown in STEP 2, Basic Connection.

 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.

 When “No Signal” message is displayed, check aerial connection.
 Adjust the aerial reception with “DVB Manual Tuning”.

Picture very infrequently breaks up 
on some or all channels.

 Electrical atmospheric interference caused by local or distant lightning 

storms or heavy rain 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.

The TV Guide information is not 
displayed properly.

 There was a programme change or TV Guide information from a broadcast 

station was possibly not correctly transmitted.
Check the current programme, e.g. on the Web site for the TV Guide 
system provider or station provider.

−

The TV Guide data is not updated.

 The unit must be in standby mode in order to update the data. If the unit 

is in EXT LINK mode (“EXT-L” lights up in the unit’s display), then the data 
update may also not work.

 Make sure that the time is set correctly.
 Check whether “Off” is set under “EPG Download in Standby” and change 

the setting in System Update in the Setup menu.
