Thanks very much for responding. I am not stood nearby the unit at the moment, just looking at the photo I took . So, can you further explain where you are seeing a wire or terminal called number 1 or number 2 ?

Trying again to upload a photo

Don't know what model I have but perhaps the photos allows someone to assist ? Suspect personally the handset microphone is the issue as we cannot hear from the house at the outside front door panel. Any suggestions as to what unit I have and what I should try to solve this , short of paying someone to say it is broken and sell me another unit, of course.
