Noise Blanker Threshold
This menu item allows the predictive noise blanker to be switched on or off and
allows the selection of three threshold levels. The noise blanker is useful to reduce
the interference caused within vehicles with petrol engines.
Note:- The noise blanker will not be effective in situations where external power line
noise etc is blanketing the receiver.
Use the Scroll keys to select the setting required (example
shown “Threshold Low”):-
press the key
Note:- In certain situations noise blankers can cause Intermodulation in receivers,
in these cases the noise blanker should be disabled.
