(From the manual)
Using a touch-tone phone, you can call your phone number from outside and access the unit to listen to messages or change answering system settings. The unit's voice guidance prompts you to press certain dial keys to perform different operations.

Remote access code:
A 3-digit remote access code must be entered when operating the answering system remotely. This code prevents unauthorized parties from listening to your messages remotely. The default

sorry what message are you getting

from a tt phone, after the message, hit * your ext # and then your pswrd.
it's just like retreiving your messages from an ext not your own.

from there you can change your access info in the admin section.
pause 5 secs and listen to the prompts from the vm syst itself.
