Setting Channel Mode
Some VHF radios offer a choice between two sets of channels,
called channel modes. If your VHF features two modes, you can
either switch between international/US channels, or between
international/BI channels.
International mode is used when sailing on any sea in the world,
except in US waters.
US mode is used when sailing in US waters.
BI mode is used when sailing on the rivers of Europe.
Setting International/US Channel Mode
If your VHF features the choice of international/US mode, switching
between those two sets of channels is done by pressing the soft key:
When US mode is selected, the yellow US indicator lamp is lit.
Otherwise, the radio is in international mode.
25W Transmitter Power Level
NB! For US channels 13 and 67.
If the VHF is programmed with the set of US channels, some of
those channels are specified to be used only with the limited
transmitter power level of 1W. This means that the TX power level
cannot be changed to 25W as described.
However, it is still possible to set the TX power level to 25W by
using:
When the key has been pushed for 1 second the TX power level will
change if allowed.
