WARNING:
This product must be independently fused with the en-
closed 3-amp fuse (or equivalent), even if you connect to
a fused accessory or power buss.
If a malfunction happens inside the unit, extensive dam-
age can occur if the enclosed fuse is not used. As with all
electrical devices, this unit could be damaged to a point
that it is unrepairable and could even cause harm to the
user when not properly fused.
CAUTION:
Do not use this product without a 3-amp fuse wired into the power
cable! Failure to use a 3-amp fuse will void your warranty.
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.
An optional 8-foot, CA-4 external power cable with a cigarette lighter
adapter is available from Lowrance.
NMEA 2000 Cable Connections
NMEA 2000 is a new buss network specifically designed for boats. This is
a very young industry standard and, at the time of printing, few boats
being built now have a NMEA 2000 buss installed. Over the next few
years, however, NMEA 2000 will become much more common. To help
you get the most out of this technology, your Lowrance unit is designed
to work with a NMEA 2000 network as soon as it becomes available.
Connecting to a NMEA 2000 Network
Your unit can be connected to a NMEA 2000 buss, receiving sensor in-
formation from any Lowrance units attached to the buss. Contact LEI
Extras (look inside back cover for accessory ordering information) for a
NMEA 2000 buss adapter cable if you would like to do this. You can
connect both the unit and antenna module through the antenna's ex-
tension cable (as described earlier), or you can connect the unit directly
to a network port. To do so, simply attach the adapter cable's manual
locking collar connector to the Network port on the back of the sonar
unit and attach the other end to an available port on the NMEA 2000
buss, as shown in the following figure.
