6. Wait while your TV scans for broadcast (antenna TV) stations...
... and then cable TV channels.
Scanning for channels can take several minutes.
Tip: Cable TV channels are channels from a cable TV provider that you can receive by connecting their cable
directly to your TV (unscrambled NTSC, ATSC, and QAM channels, if you're the kind of person who is inter-
ested in the details). In many cases, your cable provider probably requires you to use their set-top box and
connect it to a different input, and then use the set-top box to tune your cable stations. In that case, you can
skip scanning for cable channels.
7. When the channel scans finish, the TV shows the number of channels it added.
