i bought this at a garage sale and have no idea how to work it.  I cant find a manual anywhere.  Bell south only offers manuals for newer products

My daughter gave me her answering machine. She said she did not have a manuel. I can record a message but when I called the phone I could not hear the message over the phone. What's wrong? My email address is vetran_p@yahoo.com.
Thank you for your help.
