QAM is a form of modulation used in digital broadcasting.
Broadcasting operators send their services in a symbol rate by
a modulation method. Perhaps you do not have to specify the
Symbol Rate
and QAM Mode options since they are seldom
changed. However, you should set the QAM Mode option to
Auto for more certainty. You can specify the Start Frequency,
End Frequency and Symbol Rate options with the numeric
buttons if you want to change them.
If the digital receiver have failed to find every service you want
in a service search, you should set the Search Mode option to
Network
. With this option, the digital receiver will check up
the up-to-date channel information as searching services, but it
takes rather longer time.
To search only one frequency, set the Search Mode option to
Manual and specify your desired frequency at the Frequency
option with the numeric buttons. In this case, you had better
set the Network Search option to On.
It is most recommended that you should set the Search Mode
option to Quick Scan. With this option, you can search every
service rather quickly.

box appears, in which found services will be listed. When it has
completed, press the
