I require an owners manual for a Siemens A2430 cordless phone. Is this available? One of the individual phones will not work; and I cannot get to any menu to be able to dial from this Set #1.When I press "talk" to make a call, I get a message "Searching"; and when I press "end", I get a message "Please Register". The manual for this phone has been misplaced.
