Using the Foghorn
You must provide and install an optional hailer horn on the deck or tower to use the foghorn
feature. See the VHF 300 Series Installation Instructions for installation information.
The foghorn is part of the PA 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

the horn can be heard through the external speaker between soundings.
