A fine adjustment on the audio level into the DSP.
Noise
The Noise button steps through 3 noise reduction levels. Two lights on either side of the button indicate the current noise reduction level. On power up, the noise reduction level is set at zero and neither light is lit. A single press of the button activates 13 dB noise reduction. The left light is lit to show that 13 dB is engaged. A second press of the button activates 26 dB noise reduction and the right side light is lit to indicate 26 dB is engaged. A third press of the button returns you to zero noise reduction and both lights are out.

Filters
The filter inserts a series of tighter and tighter filters into the signal path to help you eliminate interfering noise while listening. The appropriate filter is determined by the signal you want to receive. There are four filter steps you can use:
No filter Voice Filter Wide CW Filter Narrow CW Filter
Each filter is suitable for a different use. No filter is the normal setting and the two lights around the button are out in this mode. When noise is bad, you can sacrifice some voice quality by using the VOICE filter by pressing the button once. This lights both lights on either side of the button and inserts an 1800 Hz filter into the audio path.
Pressing the button a second time engages the WIDE CW filter and turns on only the left light. This filter is not suitable for voice operation, but is useful for eliminating interference on CW or for narrow band digital operations.
A third press of the button engages the 100 Hz NARROW CW filter. This is a VERY tight filter suitable only for CW and very narrow band digital operations such as PSK31. You may need to adjust the receive frequency to be able to hear the signal.
A fourth press of the button, returns to the NO FILTER condition and both lights are off.
