Note: The change-password and clear password confirmation screens will not be displayed
if the front panel is disabled.
(See
Front Panel Control
in Chapter 2.)
To change or establish the automatic password, select CHANGE from the PASSWORD screen.
The change-password screen will be displayed. If a password has been previously programmed,
it will be displayed.
Use the right and left arrow pushbuttons to move from one character position to the next. The
character at the current location will flash on and off. Use pushbutton 1 to change the character
at the current cursor location to the next descending character or pushbutton 3 to change it to the
next ascending character. Use pushbutton 2 to skip through groups of characters (ascending).
Use the arrow pushbuttons to move on to the next character to be changed.
Valid Password Characters
The following paragraph applies to all APP passwords except the user password entered in the
originating modem for APP with callback:
Valid password characters are A through Z (upper case or lower case), 0 through 9 and the
following symbols: ! “ # $ % & ‘ ( ) * + , - . /
Spaces function as valid password characters;
therefore, a password that includes spaces will only match another password with spaces in
the same positions. Note, however, that a space in the first character position will disable
the password.
When the LCD cursor is in the same position as a space, the space is shown on
the LCD as a flashing black rectangle: ; otherwise, spaces appear as void spaces.
The following paragraph applies only to the user password entered in the originating modem
when configuring modems for APP with callback:
The only valid password characters are capital A through Z. If any characters outside this range
are used, callback operation will not function. No spaces between the letters are allowed, except
that the user password (as entered on the front panel) must end with a space ( ).
Entering the Selected Password
When the new password is correctly displayed on the LCD, press the ENT pushbutton. This will
cause the new password to take effect.
The modems are configured for APP without callback when matching passwords are entered in
the front panel password screens of both modems.
