I have a Starplus 616 Flex system that was working properly for a while after installation, but we had a 'brown out' power failure one afternoon and now only station 10 will ring audibly when incoming calls come in. All stations can answer, and make calls, and the intercom notices are audible, of the 6 stations we have set up, only station 10 actually audibly rings. I've tried doing a system reset via the manual, but it doesn't seem to make any difference. Switching the phones between stations does not correct anything either. All stations will ring audibly when connected to station 10 outlet.

Would love some advice on how to fix this as its difficult to hear the only one station from the other rooms in our clinic.

Thanks
Eric
