How do I get my messages off the machine when I am out of town. I don't even know if I ever set up a PIN. It's probably the default, but I don't know what to press while the outgoing message is playing in order to access my messages. I have a Uniden 2.4 ghz cordless phone with answering system. Keypad on the base and on the 4 phones that came with it. Thanks!~
