Use of key functions can be controlled by assigning operator access levels to each key (see “Operator Access
Levels” in this section and “Log In Procedure” in Section 1).
FUNCTION KEYS
Four function keys (<F1>, <F2>, <F3>, and <F4>) are located directly above the alphanumeric display (see Figure
36). Within the Main Menu options, these key definitions change as required to perform specific actions for selected
Main Menu options. The definitions for each key are shown on the top line of the alphanumeric display as an aid to
the user. A function key does not require any other key to be pressed to activate its function. Pressing a key causes
that key to immediately perform its defined task. Pressing a key which has no defined action for the current function
has no effect. However, the tone-alert acknowledges the key press with a “beep.” These four keys are associated
with advanced functions of the system within the Main Menu options, and within point displays. These keys may be
passcode protected for some of the defined operations.
The <F1>, <F2>, <F3>, and <F4> keys have extended actions defined during point displays used in conjunction with
the <FUNCTION> key (found on the DISPLAY/ACTION keypad). The actions vary with the point and status
displayed.
