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 or 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 the turbulence which will create air bubbles on 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 unit 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 unit 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 assured that the problem is in the transducer or in its
installation.
INSTALLING THE UNIT
Your Humminbird Digital has been designed for best viewing when mounted directly in front of or
to the right of the operator. This is particularly important for best viewing at night or in low light
conditions.
GIMBAL UNIT MOUNTING PROCEDURE
The unit may be mounted either on the deck or overhead, but it must be mounted on a flat, solid
surface for maximum stability. Select an area directly in front of or to the right of the operator for
best viewing, especially at night. If this is not possible, then angle the unit to ward the operator so
that you will be viewing it straight on. Before drilling holes make sure that you have room behind
the unit for the power and transducer connectors. With the slots on the gimbal bracket facing
away from you, use the gimbal bracket to locate the two screw locations. If you are mounting the
bracket to an aluminum or metal deck drill two 7/64" holes. If mounting to wood or fiberglass drill
two 9/64' holes. Mount the gimbal bracket using the two supplied self-tapping screws.
Place the unit on the gimbal bracket, making sure the rubber washers are placed
between the unit and the bracket (see Figure 11). Also, make certain that the correct side of the
gimbal bracket is facing forward.
