Security
System security is located on the System menu. It allows a supervisor or service
technician to keep unauthorized personnel from accessing the Maintenance
menu. This feature is activated on the System menu. When security is turned on,
users can only access the Main and Setup menus. The word LOCKED appears in
the upper left corner of the display to inform users that security is enabled.
Pressing the extreme Left and Right buttons (Buttons 1 and 5) on the bottom of
the display simultaneously and holding them for approximately five (5) seconds
unlocks the Security menu. If security is left ON on the System menu, when the
system times out or when the user goes back to the Main menu, security is re-
activated and the Maintenance menu is not accessable. To disable security,
access the System menu, highlight Security and press the OFF button.
