Antenna Type
Note:
Should you use a DVB-T indoor antenna (e.g. Kathrein BZD 30, visible
in the background), it must receive a power supply of 5 V. If the
antenna has its own power supply, the default setting of 5 V AUS
(inactive) must be retained.
Setting Up a Channel
Although the receiver is preassigned, it may be necessary to update
the programme list.
