Humminbird Side Imaging Transducer Manual page 5

Side Imaging® Transducer
NOTE: Side Imaging is best performed at boat speeds from .5 to 8 mph. If the boat is stationary, the same
information is displayed over and over. If the boat is moving too quickly, there will be gaps between the strips of
information. The best boat speed to use will depend on the side range selected. Slower speeds are good for
longer ranges, while faster speeds can be used at shorter ranges.
1. Adjust the angle of the transducer body first, so it is parallel with the hull of the boat. Fully tighten the
two machine screws using the supplied Allen wrench. Access the machine screws through the lower
holes in the side of the mounting bracket.
2. Next, adjust the height of the assembly so the face of the transducer is 1/8" to 1/4" beneath the bottom
of the transom, and fully tighten the three mounting screws. To access the mounting screws, pivot the
transducer assembly up into the bracket as shown in the illustration Tightening the Mounting Screws.
CAUTION! Be careful not to alter the running angle, as some force is necessary to pivot the assembly.
3. If access to the top mounting hole is not possible due to the selected height of the transducer, fully
tighten the two lower screws. Remove the headed pivot pin and the transducer assembly, tighten the
top screw, and then reassemble.
4. Confirm that the pivot angle has not changed and that all mounting screws are fully tightened.
7.
Route the Cable
The transducer cable has a low profile connector which must be routed to the point where the control head
is mounted. There are several ways to route the transducer cable to the area where the control head is
installed. The most common procedure routes the cable through the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable.
1. Confirm the cable is long enough to accommodate the planned route by running the cable over the
transom.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as
far as possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the
cable is too short, extension cables are available to extend the transducer cable up to a total of 50'. For assistance,
contact Customer Service at humminbird.com or call 1-800-633-1468 for more information.
CAUTION! Do NOT mount the cables where the connectors could be submerged in water or flooded. If cables
are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the connectors to
prevent corrosion. Dielectric grease can be purchased separately from a general hardware or automotive store.
NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough slack in the cable for this
movement. It is best to route the cable to the side of the transducer so the transducer will not damage the cable
during movement.
2a. If you are routing the cable over the transom of the boat, secure the cable by attaching the cable
clamp to the transom, drilling 9/64" diameter holes for the #8 x 5/8" wood screw(s), then skip directly to
procedure 8, Connect the Cable.
2b. If you are routing the cable through a hole in the transom, drill a 1 1/8" diameter hole above the
waterline. Route the cable through this hole, then fill the hole with marine-grade silicone sealant and
proceed to the next step immediately.
