4.4 CHANNEL STATUS GROUP SELECTION
The Channel outputs are divided into four groups of sixteen outputs each - designated A01-A16,
B01-B16, C01-C16 and D01-D16.
The sixteen CHANNEL STATUS LED’s display the status of the sixteen Channel outputs in the
CHANNEL STATUS GROUP indicated by the GROUP LED’s.
Anytime that the FUNCTION LED is lit, the current CHANNEL STATUS GROUP may be
changed by using the CURSOR utility keys.
The right CURSOR key will rotate the CHANNEL STATUS GROUP to the (i.e. A to B to C to D
to A), while the left CURSOR key will rotate the CHANNEL GROUP to the left (i.e. D to C to B
to A to D).
During execution of the SET and TEACH functions, the CHANNEL STATUS GROUP is
automatically set to the CHANNEL GROUP currently being shown on the alphanumeric display.
