HA71 Digital Gas Controller

2.4 Authorization Mode

A password entered in the AUTHORIZATION menu allows locking 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 into the 10 digit field. To lock or
unlock the system the correct 4 digit authorization number must be
entered into the Enter Code field. Point to the Unlock System entry
and press EDIT to complete the unlock procedure. It is very important
to remember the 4 digit code since the factory must be consulted if
it is lost.

the LCD contrast to a level suitable to the ambient lighting. Selecting
CONTRAST and pressing EDIT causes the UP/DOWN keys to
increase and decrease LCD contrast.
