7. Remove the water and transducer and clean the marked area and the bottom of the
transducer thoroughly.
8. Using the Humminbird Epoxy Kit or equivalent, mix an ample amount of epoxy without
causing it to bubble and pour it in the area the transducer is to be mounted. The puddle
should be larger than the bottom of the transducer.
9. Coat the bottom of the transducer with epoxy, then put it in the center of the puddle and push
down on the transducer while moving it around in a circular motion. This forces out any air
bubbles that may be trapped between the bottom of the transducer and the hull of the boat.
10. Let epoxy cure then the transducer is ready to operate. No water is now required in the
bottom of the boat and gas and oil that is spilled inside of the boat will not degrade
performance as it will if the transducer is placed only in water.
CAUTION: Do not use the silicone seal or any soft adhesive to bond the transducer to the
hull. This will reduce the sensitivity of the unit.
CAUTIONS
1. Occasionally the “eye“ of your transducer may become dirty from storage or from contact with
oils present in boats or marina environments. (Oil will cause the “eye” to lose the intimate
contact with the water which is necessary for efficient operation.) The “eye” may be cleaned
with liquid detergent.
2. Improper installation of the transducer can alter the efficiency and accuracy of the entire
system.
3. If your boat of transducer is out of the water for a period of time, it may take a short period of
time for the transducer to become thoroughly “wetted” when returned to the water. Also, re-
entry may cause turbulence, which will create air bubbles in the “eye” of the transducer. The
bubbles will disappear in a short time or can be removed by rubbing the transducer “eye” with
your fingers while the transducer is in the water.
4. If your instrument should fail to function, be sure to check all the electrical connections before
removing the transducer or calling a serviceman.
5. Inspect your transducer cable and make sure that it has not been cut or damaged to the point
where it will affect the performance of the transducer. A slight nick or cut, exposing the outer
cable, can be repaired by wrapping with electrical tape. A transducer can be damaged if the
inner cable and outer cable are allowed to make contact. Such a problem can sometimes be
corrected by properly splicing the coaxial cable. This should only be attempted by a qualified
service technician.
6. If your LCR is not working properly and you suspect the problem might be in your transducer,
we would recommend you borrow a unit from a friend and try it on your boat. If the symptoms
are the same, you can almost be certain that the problem is in the transducer.
INSTALLING THE LCR
The LCR should be mounted on a flat, solid surface for maximum stability. The low profile swivel
mount has four holes drilled in the base. It is recommended that all four holes be used.
Position the swivel base and drill four ¼” diameter holes. Note: The LCR hole pattern Is the same
as for all Humminbird flasher units. Use hardware provided to mount this base to the boat.
Next place the gimbal bracket on the swivel base and attach with four small machine screws,
provided.
Place the LCR in the gimbal mount and make certain the rubber washers provided are placed
between the unit and the gimbal bracket Important: Note which side of the gimbal faces forward.
(Slots on gimbal bracket go towards rear). Also, rubber washer must be located between the unit
and the gimbal bracket.
