Hi again Don, those little beasty pucks were put on this earth to torment us, don't drop one as they are like contact lenses, hard to locate
thats why I use a magnet to keep 'em safe. DSJR is familiar with these pucks as he use to sell Naim gear in the last century... makes you think how time flies? I use a wood tooth pick, once again to ever so gently, to pry open the rubber into shape again and with practice I hold the rings open whilst giving them a clean. I can't say it too often, be careful!
It will become second nature for your wife to use the Naim cd player.
One last tip, and this is from Naim themselves, to clean the lazer
gently use white tack, it might go under a different name (no pun) in your corner of the planet earth, by dabbing the lazer lense gently to lift off debris... go carefully and with a steady hand.
Enjoy your new CD player.
