The Transport Restore is the upper limit for the transport C/N margin setting.
The transport will be muted when the C/N margin is below the Cutoff setting,
and un-muted (e.g., restored) when the C/N margin rises above the Restore
setting for a preset period of time. The adjustable operating range is from -2.0 to
20.0 dB. The default setting for Transport Restore is 0.1.
Note: Muting Control must be set to Enable for these settings to be active.
