FUNCTIONS FOR RECEIVE

■Noise reduction

The noise reduction function reduces random noise components and enhances desired signals which are buried in noise. The DSP performs the random noise reduction function.

qPush NR to turn the noise reduction ON.

• [NR] indicator above this switch lights green.

wRotate the [NR] control to adjust the noise reduction level.

ePush NR to turn the noise reduction OFF.

• [NR] indicator lights off.

Large rotations of the [NR] control results in audio

NR [NR] controlsignal masking or distortion. Set the [NR] control for maximum readability.

■Dial lock function

The dial lock function prevents frequency changes by accidental movement of the tuning dial. The lock function electronically locks the dial.

➥ Push [LOCK] to toggle the dial lock function ON and OFF.

• The [LOCK] indicator lights when the dial lock function is in use.
