Question

I have just inherited this 2 handset telephone from my parents but with no operating instructions at all. I wanted to know how to record an answerphone message and how I operate the answerphone on the base unit. Also would LOVE to get my hands on the orginal/copy of the operating manual if you could point me in the right direction of where to get one from? Many thanks. M.Allender London
