The Trolling Motor Mount adapter, which mounts the sensor on the foot of a trolling
motor, gives excellent readings with no interference from the electric motor. Please note,
however, that the LCR 3D area of coverage is not round, but elongated side to side. As a result,
the display can become disorienting when the trolling motor is turned. Remember that terrain
shown on the left of the LCR 3D screen is to the left of the transducer, not necessarily left of the
boat.

Humminbird also offers the following accessories. Note that, for installation on a larger boat
where the transducer is located well away from the LCR 3D, you may need to purchase the 10'
sensor extension cable before beginning installation. Other accessories enhance the
performance and capabilities of your LCR 3D, and can be added at any time.
For more information on these accessories, contact your local Humminbird dealer or call our toll-
free Customer Service Hotline, listed inside the back cover.

TESTING THE INSTALLATION
After installing your transducer, LCR 3D, and cables, you should test the installation.
Testing should be performed on the water, since that is the only way to check your sensor's
performance.
With your boat at idle, press the POWER button to turn the unit on. The LCR 3D performs
a self-test on its electronics, then automatically selects the right depth range and sensitivity level
for conditions. Momentarily, you'll see the reading start to "march" across the screen from right to
left and a digital depth readout in the upper right corner.
