Lowrance electronic X37TX, X47TX

power cable when the unit is not in use. When you are not using

the unit, you should always shut off power to the power cable,

especially when the power cable is disconnected from the unit.

Power and transducer connections for the X37TX and X47TX

sonar units (direct battery connection shown).

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 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 battery or

power buss, attach one end of the fuse holder directly to the battery or

power buss. This will protect both the unit and the power cable in the

event of a short. It uses a 3-amp fuse.

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.

MOUNTING THE SONAR UNIT

You can install the sonar unit on the top of a dash with the supplied

bracket.

Bracket Installation

Mount the unit in any convenient location, provided there is clearance

when it’s tilted for the best viewing angle. You should also make sure

there is enough room behind the unit to attach the power/transducer

cable. (See the following drawings, which show the dimensions of a

mounted X37TX or X47TX.)
