Limiter is activated. This helps reduce noise 
created by the vehicle’s electronics.
 When switched to NB/ANL mode the RF Noise

RF Gain Control
The RF Gain is used to optimize reception in 
strong or weak signal areas. 
Note
The RF Gain is used to optimize 
reception in weak signal areas.
Note
The RF noise blanker is very 
effective in reducing repetitive 
noises such as ignition interfer-
ence.
 Rotate the RF Gain knob counterclockwise to 
reduce gain in strong signal areas. In weak  
signal areas turn clockwise to increase gain.
