When an optional UT-106 is installed (DSP appears 
in the function display), noise reduction function can 
be used.

The  noise  reduction  function  reduces  noise 
components and picks out desired signals which 
are buried in noise. The received AF signals are 
converted to digital signals and then the desired 
signals are separated from the noise.

q

  Push [NR] to turn the noise reduction ON.

  • [NR] indicator appears.

w

  Push [NR] for 2 sec. to enter the noise reduction 

level setting condition.

e

  Rotate  the  tuning  dial  to  adjust  the  noise 

reduction level.

r

  Push [NR] to exit the setting condition.

t

  Push [NR] again to turn the noise reduction OFF.

  • [NR] indicator disappears.

  Higher setting of the [NR] level results in audio 

signal masking or distortion. Set the [NR] level for 
maximum clarity. The noise reduction function is 
available in all modes, including AM and FM 
modes.
