International/Canada/U.S.A. Channel Maps

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