Noise reduction set mode, NR Level | Icom IC-7000 manual

5FUNCTIONS FOR RECEIVE

■Noise reduction

The noise reduction function enhances desired sig- nals in the presence of noise by using the DSP cir- cuit. The amount of enhancement is adjustable.

➥Push [NR/LEV] momentarily to toggle the noise re- duction ON and OFF.

•“ ” indicator appears when the NR function is ON.

The noise reduction level can result in audio signal

masking. Set the noise reduction level for maxi- mum readability as described below.
