I have several 8102 sets that make three fast "beeps" when you pick up the handset. I've replaced the phones and the problems go away. I assume it's an indicator that the internal battery on that phone is dead or dying. Are these batteries replaceable? I have a boat-load of these phones in service, and would hate to have to replace them all over the next year as they croak......
