2.4 HA40 System Security Menu
A 4-digit Pass Code entered and confirmed in this menu item locks all 
menus.  Viewing of menus is not denied but attempts to edit variables 
result in the “Locked” message on the LCD.
Authorized individuals locking the system should first enter a name, 
phone #, or other contact information into the 12 character field on 
the top line of the 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.
