If you enter the password the same each time, the ZIP4x4 displays the upper level. Otherwise,
the ZIP4x4 prompts you to enter the new password again. The password can be only numeric
(you can use the digits 0 to 9, the # character and the * character) and can be from 4 to 15
characters. If you try to add a sixteenth character, the phone plays the DTMF digit for the # key
and replaces the last character in the string with the last typed character.

server. If the Administrator chose to do so, the ZIP4x4 restores the password to that saved in its
configuration file the next time it powers up.
