Guys ,

Thanks for posting replies....It's a Nevo SL and my installer has an old laptop, which he is needing to replace to get a faster/newer one. I suspect that as it is old, (in computer years)that its running on windows. He has used the cable and also wireless methods to programme the Nevo. I am more than pleased with it, but these little glitches are very annoying!!! Sorry I can't give more in depth reply but all I know is how to push the buttons!!
