USING THE LCR
LEARNING TO USE YOUR LCR
LEARNING TO USE YOUR LCR
After installing the unit, transducer, and power cable as instructed, the LCR is ready for
use. By following the steps below you will be able to quickly learn how to use the LCR.
Also, trouble shooting suggestions are listed in these steps. Note: Perform steps 1
through 7 at idle or slow speed. These steps will insure that your LCR is working
properly.
Step 1
Turn your LCR on by pushing the “On” button. The LCR'S computer will automatically
adjust the sensitivity and depth scale so that in about one second you will see images
appear on the right side of the display and moving to the left. The small gap in the zero
line allows you to see movement on the display even when the bottom is not changing.
TROUBLE SHOOTING: If nothing happens when the “On” button is pushed, check your
electrical connections and fuse. Also check that the red wire on the power cable is
connected to the positive battery terminal and that the black wire is connected to the
negative battery terminal. If these wires are reversed it will not damage the LCR.
It is normal if when reversing the boat, the bottom return is lost, since air from the prop
is being forced under the transducer- remember the transducer cannot transmit through
air.
TROUBLE SHOOTING: If the display comes on when the "On" button is pushed but no
bottom information is seen, check that the transducer connector is securely locked to
the rear of the LCR. Also insure that the transducer is completely submerged. A
transducer cannot work properly in air or through air bubbles in the water.
TROUBLE SHOOTING: In very shallow water, the bottom reading might have gaps or
the scale might change to a deeper scale This is normal in one or two feet of water. The
automatic mode cannot “lock” onto the bottom in very shallow water.
Step 2
Still moving at a slow speed, begin going toward deeper water. You will see that the
LCR will display changes as small as 3 inches. Continue to move into deeper water until
the bottom return moves off the display. The LCR will automatically change to the next
deeper depth scale (indicated at bottom of the display). Notice that the entire screen is
changed to the new depth scale. This is the Total Screen Update feature.
