PRELIMINARY Unison Component Installation Procedures
6.4 Unison Component Installation Procedures
The following procedures assume that the system is new from the factory and that it
has not been programmed with a band.
If you are replacing components in a pre-installed system with either new units or
units that may already be programmed (i.e., re-using units from another system), refer
to Section 9.
