To scan cable channels, in the main menu, using the left/right buttons on the remote control.
Select the section Settings, then using the up/down buttons choose Cable and enter it by
pressing the OK button.
The user will have two options for scanning channels – Manual Search and Range Search.
First you will need to check your cable operator parameters: the frequencies at which the
broadcast is performed, used symbol rate and modulation.
In Manual Search, you will need to enter the transmitter frequency using the number buttons
on the remote control, its symbol rate and modulation. You can also choose to scan through
the NIT tables transmitted by the operator and search for only open channels. To start channel
scanning, select the Start Search line and press the OK button on the remote control.
If the parameters of the transmitter on which the channels are broadcast are entered correctly,
the bottom of the screen will display information on signal levels and the presence of errors
with drawing on interactive scales:
RF Level – signal level at the transmitter in dBuV;
BER – bit error rate when receiving a signal;
C/N – is the carrier-to-noise ratio in dB.
These parameters allow you to evaluate the quality of reception of a digital cable signal and
can be used to diagnose possible problems.
In Range Search, the operator's start, end frequencies and symbol rate are entered using the
number buttons on the remote control, symbol rate. Then choose the modulation. You can
also choose to scan only open channels. To start channel scanning, select the Start search
line and press the OK button on the remote control.
