Thanks, Joss. I’ll take you, expert, advice and ask me dealer. I had googled the subject and, as ever with TeknoMekno issues, came up with contradictory, confusing, compu-speak which assumed I knew everything and told me nothing. I got the impression that it would not be a good idea to try and fiddle with it meself, not least because I don’t own a mobile phone. Your reaction confirms it ain’t for me. Cheers…
