Ground sonar module
You can earth-ground the sonar module using the terminal on the top of the case. This
terminal is DC isolated from power to eliminate the risk of galvanic corrosion.
For installations that suffer from noise issues, the grounding terminal allows you to
connect to various possible ground points. The grounding point can be the vessel’s
bonded earth-ground, non-bonded RF ground, or battery minus (DC negative). We
recommended you use a 4 mm
2
(12 AWG) or thicker wire.
¼ Note: No DC power will flow through the connected conductor.
LED indicators
LEDs on the sonar module indicate the module’s status.
