NOTE: Humminbird is not responsible for over-voltage or over-current failures. The
control head must have adequate protection through the proper selection and
installation of a 1 amp fuse.

NOTE: In order to minimize the potential for interference with other marine
electronics, a separate power source (such as a second battery) may be necessary.
1a. If a fuse terminal is available, use
crimp-on type electrical connectors
(not included) that match the
terminal on the fuse panel. Attach the
black wire to ground (-), and the red
wire to positive (+) 12 VDC power
(Figure 3). Install a 1 amp fuse (not
included) for protection of the unit.
Humminbird is not responsible for
over-voltage or over-current failures.
1b. If you need to wire the control head
directly to a battery, obtain and install
an inline fuse holder and a 1 amp
fuse (not included) for the protection
of the unit (Figure 4). Humminbird is
not responsible for over-voltage or
over-current failures.
