1  From the user interface of the D9824, choose Input > Muting Thresholds. The 

Muting Thresholds page is displayed. 

2  Check the Enable Threshold Muting check box to mute the transport stream and 

audio in the event of an unstable, poor, or loss of signal condition. The default is 
selected. 

3  The Transport Mute for both DVB-S C/N Margin (dB) and DVB-S2 C/N Margin 

(dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, below the 
transport outputs that will be muted. The receiver uses these thresholds to 
determine when to mute the transport in the event of a noisy, poor, or loss of 
signal condition. The adjustable operating range is from -30.0 to 30.0 dB. This 
setting must be below the respective Restore value. The default setting is 0.0. 
Note: The Enable Threshold Muting check box must be selected for these 
settings to be active. 

4  The Transport Restore for both DVB-S C/N Margin (dB) and DVB-S2 C/N 

Margin (dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, above 
the transport outputs that will be muted. The receiver uses these thresholds to 
determine when to restore the transport after it has been muted. The adjustable 
operating range is from -30.0 to 30.0 dB. This setting must be above the 
respective Mute value. The default setting is 0.1. 
Note: The Enable Threshold Muting check box must be selected for these 
settings to be active.
