TROUBLE SHOOTING:
In very shallow water, the bottom reading might have gaps or the scale might change to the 0-120 foot
scale. This is normal in about three feet or less. 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 6 inches on the 0-15 foot scale. Continue to move into deeper water until the
bottom return goes off the display. The LCR will automatically change to the next deeper depth scale
(indicated at bottom of the display).
Step 3
Press the depth set button once to change to the next lowest scale. If the bottom is deeper than this
scale, the computer will automatically change back to the proper scale. By pressing the depth set
button three or four times you will see that the depth scale will change down to the 0 to 15 foot scale
and then to the 0 to 120 foot scale.
Step 4
Steps 1, 2, and 3 have verified that your LCR is working properly. You are now ready to increase boat
speed to test the transducer installation. As you increase the boat speed the LCR should give a
continuous bottom return. With a proper transducer installation your LCR will perform well at speeds
over 75 mph.
TROUBLE SHOOTING:
If at high speeds the bottom return is not continuous or there are gaps in the bottom, then the
transducer installation or location is such that air is going under the transducer face. Remember that a
transducer cannot work properly through air or air bubbles in the water. The Inside Hull Mount and
Kick-Up Mount are best for high speed operation. Refer back to the transducer mounting procedure for
adjustments or for other mounting options.
TROUBLE SHOOTING:
If when making a hard turn, the bottom reading is lost, it is the result of the transducer coming out of the
water during the turn.
