The bottom two buttons below the Mode group select protection or locking (PROT/LOCK) and clear category/number selec-
tions and/or cancel ongoing definitions (CLEAR). Protect/lock mode is described on page 6−61.
The CLEAR button will clear any category/number selection if one is in progress. If none is in progress the CLEAR button

CATEGORY AND NUMBER GROUP
Twenty buttons in a 4 high by 5 wide array form a traditional category and number group.
As an example, if the panel is configured to use category prompting, during source assignment all valid categories will illumi-
nate in green. Once a category has been selected, all valid numbers will illuminate in red. Once a category and one digit have
been selected, only remaining valid numbers will remain lit.
OPERATION
This panel can be system defined (at the file server) for:
— Multiple Destination Mode operation, front−panel selectable to Single Destination mode; or,
— Single Destination Mode only operation.
For front−panel selectable, Multiple or Single Destination Mode operation, a “Y” is placed in the Expansion column of the
MPK devices table (see “Expansion” on page 5−109). For Single Destination Mode only operation, an “N” is entered.
