Performing System Mode Operations
When you key in the correct password, the terminal enters System
Mode and the System Prompt is displayed. The System Prompt
consists of two parts: the word SYSTEM= and the terminal's
firmware version ID, in VPQXXYYZ format. (For more information
about the System Prompt, see the section entitled "The System
Prompt" below.)
In System Mode, you can the select a procedure to change the default
password to a unique and more secure password. When you set a new
System Password, be sure to keep a copy of the new password in a
secure place.
A valid System Password may consist of from one to ten
alphanumeric characters. You can change the system password at any
time, provided you know what the current password is.
When you key in the System Password to enter System Mode, an
asterisk (*) appears on the display for each character you type,
obscuring the password you are entering from general view.
However, when you press the [ALPHA] key as part of a System
Password, no asterisk is displayed.
Note: Some application program downloads automatically reset the
System Password.
Caution: If you change the System Password and then forget it, there
is no method to determine what the forgotten password is. Losing or
forgetting the password will block access to System Mode functions
and prevent you from requesting a download, performing remote
diagnostics, or changing any of the information already stored in
memory. The terminal can, however, continue to process transactions
in Normal Mode. If you forget or lose the password to your terminal,
please contact your local VeriFone representative for assistance.
