7.4 Fusion Wideband Installation Procedures

The following procedures assume that the system is new from the factory and that it

has not been programmed with bands.

If you are replacing components in a pre-installed system with either new units or

units that may already be programmed (for example, re-using units from another sys-

tem), refer to Section 8.
