WARNING:
If the power connections are accidentally reversed the system will not
work. Use a multimeter to ensure that the input power leads are
connected for correct polarity.
Switch off the display unit before you remove the power cord.
The RED wire must be connected to the feed from the positive (+) battery
terminal and the BLACK wire to the feed from the negative (–) battery
terminal. The shielded wire (screen) should be connected to the ship’s RF
ground as previously described in
Ground Connection
on page 2-20. Any
unused wires should be insulated and taped back.

interface.

Refer to
Section 2.9
for further details.
