RIDES
OVERRIDE MODE
This mode is in effect when the “OVERRIDES” button is illuminated.
Up to 10 pages of Overrides (80 total) may be defined. The up/down arrow keys may be used to access all pages containing
defined overrides. Overrides may be defined using the file server in the CP Override set assigned to the panel (page 5−96),
or, interactively by the user as described below.
Override mode may be selected from either the single or multiple destination home state by pressing the OVERRIDE button,
which will then illuminate in green. No keypad operations may be in progress. Any selected levels or audio modes are sus-
pended as overrides contain their own level and audio definitions. Selected audio and levels are restored when the user leaves
this mode by turning off the OVERRIDE button. The following display will indicate override select mode and show all de-
fined override buttons:
1 Destination = PRODCTN4
ALLBLACK ALL_BARS SET_UP_A SET_UP_B OVERRD05 OVERRD06 OVERRD07 OVERRD08
Figure 6−74. Example Override Selection Mode Menu.
User defined overrides using special audio modes will indicate this with a blinking ‘A’ to the left of the override name.
If no system (file server) or user overrides are defined for the panel, the following message will be displayed:
1 No Overrides Defined, Select OVERRIDE key to define, CLEAR to exit

Executing Overrides
All defined soft keys will illuminate in red to indicate that they are armed and ready to take an override. Selection of any so
illuminated soft key will cause the override to be immediately selected at the previously selected destination(s). No subse-
quent TAKE operation is required. In multiple destination mode, the output may be selected before or after pressing the
OVERRIDE button.
The top destination line functions in the same manner as defined in the multi destination mode section; it can show up to six
destinations; for over 6, the display indicates multiple destinations with ellipses (...).
An override may be applied to a destination that does not match the levels defined for that override. When this situation occurs,
the user will be warned with either of the two messages shown on the top line (as appropriate):
