Setting Up Dish Pointing
Setting up Muting Threshold Controls
Proceed as follows to set up the muting threshold controls:
Step 1 From the user interface of the D9865, choose Input > Satellite > Tuning Setup > Muting Thresholds.
The Muting Thresholds page is displayed.
Step 2 Check the Enable Threshold Muting check box to mute the transport stream and audio in the event of
an unstable signal, poor signal, or no signal condition. The default is selected.
Step 3 The Transport Mute and Restore for both DVB-S C/N Margin and DVB-S2 C/N Margin sets how the
receiver reacts when the signal quality is severely degraded when using DVB-S or DVB-S2 modulation.
This allows you to set the transport C/N margin values for the receiver. The receiver uses these noise
values/settings as limits during normal operation to determine whether to mute the transport in the event
of a noisy signal, poor signal or no signal condition.
The Transport Mute is the lower limit for the transport C/N margin setting. The transport will be muted
when the C/N margin is below the mute setting for a nominal delay of 1 second. The delay is between
the time the condition is first detected and the time the transport is muted. The adjustable operating range
is from -5.0 to 20.0 dB. The default setting for Transport Mute is 0.0.
The Transport Restore is the upper limit for the transport C/N margin setting. The transport will be
un-muted (e.g., restored) when the C/N margin rises above the Transport Restore setting for a nominal
delay of 8 seconds. The delay is between the time the condition is first detected and the time the transport
is muted. The adjustable operating range is from -5.0 to 20.0 dB. The default setting for Transport
Restore is 0.1.
