NVOY™ TRANSCEIVER REFERENCE MANUAL

Reducing background noise with Easitalk™

The Easitalk™ feature enables you to reduce the level of background noise that is

present when you listen to a channel.

NOTE: Easitalk™ uses one of three DSP algorithms to reduce the background

noise. Depending on the conditions, you may need to change the

algorithm in Settings > Configuration > General > Easitalk

Mode.

To switch Easitalk™ on or off:

1 Press EASITALK.

The new status is shown briefly in a pop-up, then you are returned to the screen

that you were on previously.
