2.4 System Security Menu
A 4-digit Pass Code entered and confirmed in this menu item locks
all menus. Viewing menus is not denied but attempts to edit variables
flashes the Locked message on the LCD.
Authorized individuals locking the system should first enter a name,
phone #, or other contact information in the 12 character field on the
top line of the
System SECURITY
screen. To lock or unlock the system
the correct 4 digit authorization number must be entered into the Pass
Code field. It is very important to remember the 4 digit code since the
factory must be consulted if it is lost.
