Operator and All List Parameters
This complete list of parameter settings is arranged so that the settings
most likely requiring changes are placed at the top of the list. Items on
the bottom of the list are the least likely to require changing. Parameters
with the designation [RO] are “read-only.” An asterisk (*) indicates the
default user range or value.
The All List is a long flat list of all the available parameters, arranged
from the most-used to least-used. It is intended for a “Supervisor”
security designation. The Operator List is a condensed version of the
All List, and is intended for an “Operator” security designation. The
following table shows all available parameters. Parameters accessed
only from within the All List are shaded in gray.
See
“Navigating the Operator and All Lists” on page 30 for instructions
on navigating this list using card-edge controls.
Note
You can reset the default values
for all of the parameters
automatically via the
FctryRcl
parameter, found in this table.
