■
Ground connection
To prevent electrical shocks and other problems, ground the display unit through the [GND] terminal. For best re-
sults, 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.
■
Power source requirement
D
DC power source
The display unit is designed for connection to any
power source if the voltage is 10.2–42 V DC, so that
a 12, 24, or 32 V DC battery can be used without a
DC-DC converter, or any internal modifications.

DC power cable connection
Connect the supplied DC power cable as shown in
the diagram.
