U.S.A./International/Canada Channel Maps
Three (3) sets of VHF channel maps have been established for marine use in the
U.S.A., Canada, and the rest of the world (International). Most of the channels
are the same for all three maps, but there are definite differences (see table on
pages 12 through 21). Your radio has all three (3) maps built into it and will
operate correctly in whichever area you choose.
