Hi,

First try an optimize. This is in the settings menu under ecosystems on the remote.

If that does not help then the easiest test to do is to unplug the NC-50 and take it to another location (work) and see if it works OK. No need for the emitters as each port will flash anyway. If it works then there is an interference issue at home. Possibly the neighbors have something new? If it fails there they talk to Nevo tech support as something may have failed.

This is only basic fault finding but effective.
