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 w

by rotating up out of the metal spring bracket without harming the transducer, or your boat. The transducer can be re-engaged by simply rotating the transducer down and snapping it back in place. (See Figure A) B. Inside Hull Mount- The high speed transducer can be mounted inside the hull (without pivot assembly) using the proper two-part epoxy, such as Humminbird’s epoxy kit. Even though there is some loss of signal in shooting through the hull, your LCR will perform well with this

Once the location is determined mark and drill three 7/64” dia.. holes noted on the template. Attach the metal bracket using three #10 self threading screws supplied. Be sure to align holes in the center of the Bracket slots. On some aluminum boats it may be necessary to use a wood back-up plate. It is important to use a silicone sealant between the screwhead and bracket in order to prevent leaking. (See Figure C) Step 2. BRACKET INSTALLATION (Fiberglass Boats)- If your boat h

NOTE: On boats with more than 15 degree deadrise angle it may be necessary to mount the transducer slightly off parallel with the water level. (See Figure E) Mark and drill the three 9/64” dia. holes as shown on the template. Attach the metal bracket using the three #10 self threading screws supplied. Be sure to align the holes so that they are centered vertically in the three slots found in the bracket. It is important to use a silicone sealant between the screwhead and bracket in or

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 ¼”x3/8” allen head screw into the end of the pin and tighten. (See Figure G) Step 5 ANGLE ALLIGHMENT- Set the transducer angle so that it is parallel with the bottom of the boat hull. Once p

wrench provided. The screws are visible through the access holes on each side of the metal bracket. Check to make sure the transducer main body is rigidly fastened to the pivot. (See Figure H) Step 6 CHECK POSITION OF TRANSDUCER- At this point, check to see that the bottom of the transducer is a minimum of ¼” 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 assem

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 mot

OTHER MOUNTING OPTIONS 1. The LCR gimbal bracket can also be mounted on the SM-4, quick disconnect swivel mount. 2. The LCR gimbal bracket can also be mounted directly to the dash without the swivel mount, however, this method is not recommended since the unit cannot be rotated.

It plugs into the outlet on the back of the unit marked “Power”. The transducer connector is identified with the letter T and plugs into the outlet on the back of the unit marked “Transducer”. Note: An adapter (AD-4) is available to allow use of an old waterproof (BNC) transducer with the LCR, but be sure that the transducer is a 16degree. A 32-degree transducer cannot be used. A 11/8” hole must be drilled to pull through the transducer connector. After drilling the hole, pull the transduc

OPERATIONAL INSTRUCTIONS FOR LCR 3004: The Humminbird LCR 3004 will operate fully automatic or manual at the discretion of the operator. At the heart of the LCR 3004 is a microcomputer which is making thousands of decisions every second. With the LCR 3004's automatic features you will quickly and easily learn the basics of operating your unit and after a couple of trips on the water you'll be operating the LCR like an expert. It is suggested that you familiarize yourself with each of the

Manual Mode - There are two ways of putting the LCR 3004 in the manual mode: (1) depress the Auto "On/Off" button or (2) depress either the manual decrease (-) or increase (+) button. You will notice that the word "Auto" in the upper right hand corner of the display has gone off. The operator can control the amount of sensitivity by depressing the (+) or (-) button. There are 15 sensitivity settings. When the (+) or (-) button is pressed once, the sensitivity setting at the top of the scree

You should also note that it is possible to have the sensitivity set too high such that reflection off of suspended matter or air bubbles will begin to black out the display. In the manual mode the depth scale does not change automatically and the digital bottom depth is not displayed. To once again activate the automatic mode, depress the Sensitivity Auto "On/Off" switch. 5. Audible Alarms: The LCR 3004 is equipped with two audible alarms, a Fish Alarm and a Bottom Alarm. Fis

Turn off the Bottom Alarm by again pushing the alarm "On/Off button. The alarm setting will then go to zero. If the alarm is turned on again before the unit is turned off, it will still be set at the previous setting. 6. Display: Stop/Resume: Anytime during the operation of the LCR, the operator may "freeze" the display by simply pushing the display "Stop/Resume" button. This feature will aid in the learning and interpretation of the signal on your LCR display by giving you time to stud

LEARNING TO USE YOUR LCR: After installing the unit, transducer, and power cable as instructed, the LCR is ready for use. By following the steps below you will be able to quickly learn how to use the LCR. Also, trouble shooting suggestions are listed in these steps. Note: Perform steps 1 through 6 at idle or slow speed. These steps will insure that your LCR is working properly. Step 1: Turn your LCR on by pushing the "On" button. The LCR's computer will automatically adjust the sens

Step 2: Still moving at a slow speed, begin going toward deeper water. You will see that the LCR will display changes as small as 3 inches on the 0-15 foot scale. Continue to move into deeper water until the bottom return goes off the display. The LCR will automatically change to the next deeper depth scale (indicated at bottom of the display). See Figure 15 for a display of a typical range change from 0-30 foot scale to 0-60 foot scale, You will notice that now the bottom is about half w

LEARNING TO READ THE DISPLAY The following illustrations show some typical display with bottom, structure, and target returns. These should help you in interpreting the information being displayed on your LCR. Surface clutter: The STC in your LCR will normally eliminate surface clutter, however, in some water conditions or when going across the wake of a boat the surface clutter will appear as shown above.
