CAUTION: Incorrect cable connection may dam- age the radar.
The radar is designed for connection to any power source if the voltage is
•DC power cable connection
Connect the supplied DC power cable as shown in the diagram.
■Ground connection
To prevent electrical shocks and other problems, ground the display unit through the [GND] terminal on the unit’s rear panel. For best results, connect a heavy gauge wire or strap to the nearest grounding point on the boat. The distance between the [GND] terminal and the ground point should be as short as possible.
