USING THE LCR

 

LEARNING TO USE YOUR LCR 

 

Step 7

 

 
Press the Fish Alarm on/off button. Notice the indicator in the lower part of the screen 
indicating the Fish Alarm is on. Now if an object is detected between the surface and 
the bottom, a short alarm sound will be heard. By pressing the Fish Alarm on/off button 
again the Fish Alarm is turned off. 

 
Step 8

 

 
Steps 1 through 7 have verified that your LCR is working properly. You are now ready to 
increase boat speed 

to test the transducer installation

. As you increase boat speed 

the LCR should give a continuous bottom return. With a proper transducer installation 
your LCR will perform well at speeds over 75mph. 

 
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 through air bubbles in the water. Refer back to the transducer mounting 
procedure for adjustments or for the 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.
