The NEDSP has three adjustments:
•
Input signal level
•
Output signal level
•
Beep volume
The input and output levels do not normally need to be adjusted (see troubleshooting
section). Rotating anticlockwise will increase the level.
The beep volume can be adjusted to suit the user. Rotating P3 anti clockwise will increase
the beep volume.
The beep can be disabled, by turning the volume control fully clockwise.
Ensure all connections are replaced.

Detune the FT-817 to receive static.
Press and release the DSP button, the unit will beep to indicate
which filter level is selected ( 1 beep for level 1, 2 for level 2
etc.).
The led will also flash in green at the same time. The noise level
will now be reduced.
Repeat this for all 4 filter levels. (see the operating instructions
at the end of this document for more information).
Press the button again and the noise cancellation will be switched
off, and the LED illuminate red.
If the unit operates correctly then replace the lid. Affix the supplied
label over the switch and LED.
