How to make handsets ring whenever a call comes in?
Recently bought Panasonic cordless phone system KX-TG985SK (handset KX-TGFA71). It has 5 handsets & as far as I can tell, at least 2 of the handsets won't ring when a call comes in. Silent Mode is off. When a call comes in, the little bell icon (I think Pana calls it a speaker) in the lower left of the handset screen is slashed out. I have tried taking out the batteries for 2 mins. I have also tried setting silent mode for 2 mins at 11:59 PM to 00:01AM. Makes no difference. If I raise the volume when a call comes in, the phone rings, but won't on the next call. How do I get these handsets to ring all the time?
