Re: PANASONIC KX-TD1232 CE - PBX hybrid - Dial tone problem

One more small contribution to solving the problem
Start by removing only IC6.
When I say "removing" it is removing the integrated without replacing it.
The same work in the paging of the equipment (amplifier for announcements by external speakers)
MC145503P It also appears in the doorphone interface, if the equipment uses a doorphone interface, start by leaving the interface unconnected and try.
