These keys can be pressed anytime, and the key feedback (beep) may be the only acknowledgment of the action.
Typically, the LED tracks the function and illuminates each time the associated key is pressed.
Use of key functions can be controlled by assigning operator access levels to each key (See Section 9, Operator
Access Levels, and Section 1, Log In Procedure).
FUNCTION KEYS
Four FUNCTION KEYS (cFi>, <F2>, <F3>, and cF4>) are located directly above the alphanumeric display (See
Figure 34). 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 cFl>, cF2>, cF3>, and cF4> keys have extended actions defined during point displays when used in
conjunction with the <FUNCTION> key on the DISPLAY/ACTION keypad. The actions vary with the point and status
displayed.
