•
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 supplied 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".
•
Perform "Auto-Setup Restart" in the Setup menu.
•
Electrical atmospheric interference caused by local or distant lighting 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 station sorting of this unit is pre-defined. Use profiles to sort the stations
as you want them.
•
Select the length of time (3-10 sec.) in the "On-Screen Messages" in the Setup menu.
•
The digital channel information will not appear during playback or recording.
•
Perform "Auto-Setup Restart" in the Setup menu.
•
When subtitle is on or additional information in the digital channel information
is displayed, Digital TEXT does not work.
•
Perform "Auto-Setup Restart" in the Setup menu.
•
"Shipping Condition" was performed or the unit was in the delivery status. The
Auto-Setup was then started and interrupted.
Do an Auto-Setup again and let it continue right through to the end. The data
is only saved after this has been completed.
•
Reduce the signal amplification at your aerial.
•
Overmodulation makes the signal strength display go to red. Readjust the
picture with your room aerial until the picture quality improves.
TV Guide
•
Check whether the clock is properly set.
•
If signal quality is bad (ghost images or limited reception), the TV Guide
system may not be able to receive any data.
•
Perform "Auto-Setup Restart" in the Setup menu.
•
Some stations are not supported by the TV Guide system.
•
Programme the Timer recording manually.
•
Perform "Auto-Setup Restart" in the Setup menu.
•
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 unit must be in standby mode in order to update the data. If the unit is in
EXT LINK mode ("EXT-L" lights on 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 "TV Guide Download in Standby" and change
the setting in System Update in the Setup menu.
Sound

–
When a DVD-R, DVD-R DL, DVD-RW (DVD-Video format), +R, +R DL or
+RW disc is in the disc tray

•
When recording a digital broadcast with multiple audio channels, this unit will
record only the audio channel selected in "DVB Multi Audio" in the on-screen
display. The audio channel cannot be switched during playback.
•
You have used a digital connection. Set "Dolby Digital" to "PCM" or connect
using audio cables (analogue connection).
•
There are discs whose audio cannot be changed due to how the disc was created.
