NR
Noise Reduction
The Noise Reduction function reduces random noise
components and enhances audio signals which are
buried in noise. The received signals are converted to
digital signals and then the audio signals are separated
from the noise.

• “NR” appears.
Hold down w

(C) for 1 second to display the “NR”
screen (Noise Reduction).
Rotate the Dial e to adjust the Noise Reduction level;
rotate it clockwise to higher reduction level or coun-
ter clockwise to lower reduction level.
• If desired, touch [DEF](D) for 1 second to reset to the
default setting.
• The adjustable reduction level is between 1 and 15.

(C) to turn OFF the Noise Reduc-
tion.
A large rotation of the “NR control” results in audio
signal masking or distortion. Set the “NR control” for
maximum readability.
