3.4 Configuration menu
The (F) in the text represents the factory default setting. The unit can be
factory defaulted by holding in any one of the DIAL buttons while
powering up the unit, or inserting it in the shelf.
As System, Command Port and Alarm Port menus are not
available in the shelf mounted unit, these menus are “starred”
as unavailable on the terminal screen. Refer to the SBU
Systems manual for details of how to set the Manager card
command port.
The shaded menus apply to the backup modules only, i.e. SBUQLB,
SBUQHB.
