NOTE: Foghorn functionality is not available on all VHF radio

Before you can use the foghorn, you must provide and install a
hailer horn (optional) on the deck or tower of your boat. For
more information, see the Installation Instructions.
The foghorn is part of the public address system of your radio.
You can sound the foghorn through a hailer horn or an external
speaker. Your radio can sound the horn automatically using
standard patterns, or you can sound the horn manually. When
you manually operate the foghorn, sounds received through the
horn can be heard through the radio speaker between

setting is 200 Hz, and the maximum setting is 850 Hz. The
default setting is 350 Hz. Regulations dictate the correct
frequency of foghorns, which correlate with the size of your

Compatible radio models are programmed with 10 WX channels
to monitor weather broadcasts from the National Oceanic and

regularly. NOAA broadcasting information is regional and
relevant to your broadcast area.

DSC radio, like a telephone number.
Digital Selective Calling (DSC) is a key component of the Global
Maritime Distress and Safety System (GMDSS). DSC enables
VHF radios to place and receive digital calls directly with other
vessels and shore stations, including the USA and Canadian
Coast Guards. Your radio includes full Class-D DSC capabilities.
If you have a GPS device connected to the transceiver, your
latitude, longitude, and the current time are transmitted when
you send a distress call or other type of DSC call. If you enter
your position information manually, your latitude, longitude, and
time of entry are transmitted with the call. Transmitting your
location automatically speeds help in an emergency situation.
Channel 70 is reserved exclusively for DSC calls, and your
device uses a dedicated receiver to maintain a constant watch
on Channel 70. You do not need to change the channel to make
a DSC call. Your device changes to Channel 70 automatically to
transmit a DSC call. Your radio sends the DSC data over
Channel 70 in less than one second, and then tunes to an
appropriate channel for voice communications.
