TV channel identifier
The channel identifier is displayed for several seconds every time the
channel is changed or by pressing the

button. The antenna
symbol at the top left indicates that a channel is received even if no
picture can be seen (e.g. radio). The TV symbol indicates a TV
channel with the selected channel shown next to it and whether video
text is received. The time is also indicated. The + in the third line
stands for the channel selection from the main channel list. If the
favourite list is selected, you will see the "apple" symbol at this point.
This is followed by the programme title as well as the start and end
times of the current programme, provided these data are transmitted
with the signal.
Radio channel identifier
The identifier for the set radio channel has the same configuration.
The radio symbol in the top left corner indicates that this is a radio
channel. Programme times and text are displayed only if the
corresponding data are transmitted with the signal.
Error message
"Bad or no signal" indicates that there is a fault in the reception
system or in the receiver settings or the transponder is not
transmitting. Check the antenna connection and antenna
configuration. As an aid, refer to the list of service settings provided at
the end of this User's Guide.
