Configuring The Navigation Light Option; Using The Bilge Pump Switches; Using Dimmable Lights - Garmin GPSMAP1222 Owner's Manual

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.
1 From a Garmin chartplotter connected to the same NMEA 2000 network as the Garmin Boat Switch device,
select Vessel > Switching.
2 Press and hold switch 1 for 5 seconds.
Switch 1 starts flashing.
3 Press and hold switch 2 for 5 seconds.
The switch stops flashing, and a message confirms the newly selected wiring option.
4 Repeat the previous two steps until the device is configured for the wiring option that applies to your
installation type.
NOTE: After selecting option C, the next configuration option in the cycle deactivates the interlocks so that
channels 1, 2, and 3 operate independently as normal latching switches.

Using the Bilge Pump Switches

You can manually operate connected bilge pumps by using switches 12 and 13 on the Garmin chartplotter.
1 From a Garmin chartplotter connected to the same NMEA 2000 network as the Garmin Boat Switch device,
select Vessel > Switching.
2 Select an option:
• Press and hold the bilge pump switch for one second to run the bilge pump for 2 minutes.
• Press and hold the bilge pump switch for three seconds to run the bilge pump continuously.
NOTE: Your Garmin chartplotter notifies you every 5 minutes while continuous mode is active.

Using Dimmable Lights

You can operate connected dimmable lights by using switches 17 through 21 on the Garmin chartplotter.
1 From a Garmin chartplotter connected to the same NMEA 2000 network as the Garmin Boat Switch device,
select Vessel > Switching.
2 Select an option:
• Press a dimmable light switch to turn a light on or off.
NOTE: The light turns on at the dim level set when the light was last turned off.
• With a light on, press and hold a dimmable light switch dim the light, and release to stop dimming.
