I acquired a BEOTALK 1200 answering machine without the AC power adapter.  I have determined that the power requirements are 9 VDC @ 300 mA.  However I need to know the polarity of the power plug - and would be most grateful if someone could tell me which pin is positive (+) or, even better, help me obtain a schematic.

Thank you in advance,

Michael

Sorry for the C&P, I am mobile this weekend or I would help further.

Thanks for the response Burantek.  Does the power adapter use the same jack on the BEOTALK 1200 as the telephone line or is there a separate jack for the power adapter?  I have not actually seen the unit.  It's on ePay and I am considering making a bid on it.  If the power adapter shares the jack on the BEOTALK with the telephone line I would need to find some kind of wiring diagram so I can solder two wires directly to the PCboard to connect to a 9VDC power line or simply forget buying this particular BEOTALK 1200.
