7.4 Fusion 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.
