Power source requirement
DC power source The radar is designed for connection to any power
source if the voltage is 10.242 V DC, so that a 12, 24,
or 32 V DC battery can be used without a DC-DC con-
verter, or any internal modications.
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 units
rear panel.For best results, connect a heavy gauge wire or strap to the nearest grounding point on the boat. The dis-
tance between the [GND] terminal and the ground point should be as short as possible.
CAUTION: Incorrect cable connection may
damage the radar.
