Navigation and Anchor Light Wiring
The first three channels on this device can be used for navigation lighting to satisfy the international regulations
for preventing collisions at sea. Depending on the navigation-lighting configuration on your boat, you can
choose from three different options for activating these lights.
NOTE: You can view examples of common wiring installations including these navigation light options on the
Garmin website. Go to garmin.com/manuals/boatswitch/.
Option A (default): One connection for red/green navigation lights, and one connection for white navigation/
anchor lights (Navigation Lights Option A, page 13).
Option B: One connection for red/green/white navigation lights, and one connection for anchor lights
(Navigation Lights Option B, page 14).
Option C: One connection for red/green/white navigation lights, one connection for steaming lights, and one
connection for anchor lights (Navigation Lights Option C, page 15).
Deactivated: The first three channels are not interconnected, and act as assignable independent switches.
These switches can still be used for lighting, but connected lights must be turned on and off independently of
one another (Configuring The Navigation Light Option, page 22).
