The  noise  reduction  function  reduces  random  noise 
components and enhances desired signals which are 
buried in noise. The DSP does the random noise re-
duction function.

q

  Push the [NR] to turn the noise reduction ON.

  • [NR] indicator above their switch lights green.

w

  Rotate the [NR] control to adjust the noise reduction 

level.

e

  Push  the  [NR]  switch  to  turn  the  noise  reduction 

OFF.

  • [NR] indicator lights off.

Deep  rotation  of  the  [NR]  control  results  in  audio 
signal masking or distortion. Set the [NR] control for 
maximum readability.

■

The  digital  selector  manually  adjusts  the  center  fre-
quency of the automatic pre-selector. The digital selec-
tor functions within 1.5 MHz to 29.999999 MHz range.

The automatic pre-selector adds selectivity ahead of 
the 1st mixer. This reduces intermodulation distortion 
from the nearby strong signals.

The automatic pre-selector tracks the frequency tuning, 
changing it’s resonant frequency in discrete steps.

q

  Push [DIGI-SEL] to turn the digital selector ON or 

OFF.

  •  [DIGI-SEL] indicator above their switch lights green.

w

  Rotate [DIGI-SEL] control to adjust the center fre-

quency.

NOTE: 
•  When rotating [MAIN DIAL] 

(or sub dial during du-

alwatch or split function)

 while the digital selector is 

activated, mechanical noise may be heard due to 
the switching noise from internal relays. 

•  The preamp (P.AMP1 or P.AMP2) cannot be used 

while the digital selector is activated.
