Noise Blanker

The Noise blanker eliminates pulse-type noise such
as the noise from car ignitions.
The Noise blanker cannot be used in the FM mode.
Push NB to turn the Noise Blanker ON or OFF.
NOTE: When using the Noise Blanker, received signals
may be distorted if they are excessively strong or the noise
is other than a pulse type. In that case, turn OFF the Noise
Blanker, or shallow the DEPTH on the NB menu.
