Hi I have had BT8500 with quad handsets for 3 years - great but in last 9-12 months the handsets go dead, often in middle of call or when you are trying to answer a call. Tried new batteries but still happening and when they come back after being put on base unit the batteries show full, so not battery problem.
I have tried re-setting handset - no good.
When you put the dead phone back on the base unit, after a few seconds, it displays "synchronising data". The problem is not specific to one particular handset. I have also recently had it display "test mode"
Any thoughts or suggestions
I've been experiencing the same problem. Some handsets don't ring or when they do you can't answer the call with the handset.
Doesn't look like anyone can comment on this problem.
What have you done about it?
I have the same problem the phone cuts out on calls incoming or out going. It is driving me nuts.
Did you find a solution?
I wondered if it was the batteries but the phones say fully charged.
Many thanks Seeker43
