this unit could be damaged to a point that it is irreparable and
could even cause harm to the user when not properly fused.
Failure to use a 3-amp fuse will void your warranty.
If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
noise. If the cable is not long enough, splice #18 gauge wire onto it.
The display power cable has two wires, red and black. Red is the positive
(+) lead, black is negative (–) or ground. Make sure to attach the in-line
fuse holder to the red lead as close to the power source as possible.
For example, if you have to extend the power cable to the power bus or
battery, attach one end of the fuse holder directly to the power bus or
battery. This will protect both the unit and the power cable in the event
of a short.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
