Automatic scan: networks, NIT and clearing

Menu → Setup → Tuners, Scanning & Reception → Automatic Scan. This dialog searches configured reception networks. Initial frequencies come from tuner configuration and available frequency lists or supported discovery routines.

Native initial form: Clear before scan is Yes here. Change it to No for an additive scan. No scan was started. Open original image ↗

Field	Decision
Network scan	Use received NIT data to find further frequencies; not a LAN/Internet search
Scan tuner / network / satellite	Select only the intended, connected reception paths
Clear before scan	No keeps older services while updating/adding; Yes rebuilds the affected scope; Keep feeds is a limited exception

Up/down selects a row and left/right changes it. Green/Scan or OK starts scanning according to the displayed key assignments. Red/Close or EXIT leaves the form. After starting, follow the progress dialog’s labels; cancelling leaves the selected scope only partly searched.

Enigma2 may consolidate the same reception network across several tuners. Selecting the right network matters more than enabling every row. A hybrid tuner searches enabled reception types in sequence. Long scans occupy resources otherwise needed for television or recordings.

After completion, check the number and type of discovered services. Look under All, Satellites or Providers in the channel list; new services do not automatically occupy your preferred position in a personal bouquet. No results: check the signal and test one known frequency with manual scan. Compare all scan methods.
