Configuring the Navigation Light Option
It is your responsibility to comply with applicable laws, regulations, and standards related to the use and/or operation of marine navigation lights. Garmin® is not responsible for any fines, penalties, citations, or damages that may be incurred due to any such lack of compliance.
By default, channels 1 and 2 are interlocked for navigation lighting to satisfy the international regulations for preventing collisions at sea. Depending on the lighting specifics of your boat, you may need to configure the Garmin Boat Switch™ device to use the wiring option you that applies to your installation type.
If you do not intend to connect navigation and anchor lights to the device, you can configure channels 1 and 2 to operate independently as normal latching switches.
