User manual HUMMINBIRD DEPTH SOUNDER

[. . . ] TRANSDUCER MOUNTING PROCEDURE Humminbird's high-speed transducer is supplied with your LCR. This transducer has been designed to give good high speed readings on most all boat designs, including aluminum. Please carefully consider the following before installing your transducer. TRANSDUCER MOUNTING OPTIONS A. Transom Mount- The Humminbird high speed transducer allows the transducer element to be mounted below the bottom of the boat hull keeping the transducer out of turbulent water and insuring good high speed operation. [. . . ] HOWEVER, DO NOT TIGHTEN AT THIS POINT (See Figure 7). CAUTION: DO NOT APPLY LOCTITE® OR SIMILAR LOCKING COMPOUNDS BECAUSE THEY WILL ATTACK THE PLASTIC. Step 4 TRANSDUCER ASSEMBLY -Insert the transducer assembly into the metal bracket from the bottom. Push up until the holes in the plastic pivot align with the uppermost holes in the bracket. Slide the O-ring on to the headed pin and insert it through the two parts. Assemble by screwing the '/, "x%" alien head screw into the head of the pin and tighten. Step 5 ANGLE ALIGNMENT - Set the transducer angle so that it is parallel with the bottom of the boat hull. Once proper alignment is achieved, tighten the two alien head screws using the %2" alien wrench provided. The screws are visible through the access holes on each side of the metal bracket. Check to be sure the transducer main body is rigidly fastened to the pivot. Step 6 CHECK POSITION OF TRANSDUCER At this point, check to see that the bottom of the transducer is a minimum of %, " below the bottom of the transom. (However, as noted in STEP 2, the top of the transducer cannot fall below the bottom of the transom). If it is not, remove the transducer assembly from the metal bracket by removing the pin installed during STEP 3. Loosen the metal bracket mounting screws, reposition the bracket utilizing it's slotted holes, tighten and reassemble. It may be necessary to replace the silicone sealant after this adjustment is made. NOTE: It may be necessary to make several high speed runs to adjust transducer either UP/DOWN or to readjust the angle to achieve optimum results. Step 7 CABLE CLAMPS - Install cable clamps as necessary by drilling a %' dia. Be sure to route the cable to the side of the bracket. The cable can be cut if it is installed in the center of the bracket. FIGURE 10 3. INSIDE HULL MOUNTING PROCEDURE Warning: In order to achieve proper results with this type installation, it is important that the transducer be mounted by someone familiar with the use of two part epoxy adhesives. For this reason, Techsonic Industries, Inc. will not be responsible for any damage due to the mounting of your transducer in this manner. IMPORTANT: Be sure to follow steps 3 through 6 to insure that a proper mounting location is found. Do not epoxy the transducer until this is done. [. . . ] Rub water into the face of the transducer to provide for proper wetting. If transducer is mounted inside boat, refer to page 10. Cannot Obtain High Speed Reading If transducer is mounted inside boat, refer to page 7. If transducer is mounted on outside of boat, check to see that transducer is on driver's side and is flush with the bottom and transom of boat. [. . . ]
