2.1.4.5 Channel Management
This page displa ys all of the relevant information regarding the regions established
either by manual entry, a governing authority’s VTS station broadcasting region infor-
mation, or another Universal AIS broadcasting the data. These regions determine
the authorized operating frequencies for the coverage area. The user can set these
different configurations at the initial setup; however, the L-3 ProTec Transponder will
acquire the data for a new region once it has entered the region.
