    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.

  • Page 4: Transom Installation

    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 type of installation.
  • Page 5 aluminum boat locate the template on the transom between rows of rivets, or ribs that are on the bottom of the boat. Align the template so that the bottom corner of the template nearest the center of the transom is on the bottom edge of the transom. Once the location is determined mark and drill three 7/64”...
  • Page 6 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.
  • Page 7 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.

    For this reason, Techsonic Industries, Inc. will not be responsible for any damage due to the mounting of your transducer in this manner. NOTE: An Epoxy Kit (Part N. EPK) is available from Humminbird. This Epoxy Kit has been formulated for Inside Hull Transducer Installation.
  • Page 9 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.

    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.
  • Page 11 INSTALLING THE CABLES Your LCR comes equipped with Humminbird’s new Angle-Lock power and transducer connectors. The power connector is identified with the letter P on the back of the plug.
  • Page 12 “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 transducer connector up through the hole.

  • Page 13: Installation

    Note: it is often necessary to make several incremental transducer adjustments before optimum high-speed performance is achieved. Important: For Transom Mount transducer installations, install the third mounting screw after the final transducer adjustments. Humminbird 3 Humminbird Lane Eufaula, Alabama 36027...

  • Page 14: Introduction

    USING THE LCR 4000 INTRODUCTION Before attempting to install or operate your Humminbird LCR, it is recommended that you read the operations manual thoroughly. The LCR is a totally new concept in sonar and has a number of special features not found on any other recorder. To completely understand all the features of your unit, we suggest you follow the instructions set forth in this manual.

  • Page 19: Operational Instructions

    OPERATIONAL INSTRUCTIONS OPERATIONAL INSTRUCTIONS FOR LCR4000 The Humminbird LCR4000 will operate fully automatic or manual at the discretion of the operator. At the heart of the LCR is a microcomputer which is making thousands of decisions every second. With the LCR4000'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 LCR4000 like an expert.
  • Page 20 USING THE LCR 4000 OPERATIONAL INSTRUCTIONS You may also manually change the depth scale by pressing the depth set button. Each time this button is depressed, the range is decreased by one setting. For example, if you are on the 0-30 ft scale, pressing the depth set button once will change the scale to 0-15 ft.
  • Page 21 (See Figure 15). USING THE LCR 4000 OPERATIONAL INSTRUCTIONS indicating more sensitivity. In shallow water or when a hard bottom is being read, the sensitivity needed to achieve a good return will be less.
  • Page 22 USING THE LCR 4000 OPERATIONAL INSTRUCTIONS Note: You will find the manual sensitivity control more useful when looking for smaller targets such as smaller fish. In the automatic mode the computer might not be using enough sensitivity to show smaller targets. At higher sensitivity more targets will be seen.
  • Page 23 USING THE LCR 4000 OPERATIONAL INSTRUCTIONS To begin transmitting and receiving of new information after using Reverse or Forward, simply press the Stop/Resume button. The display will change back to the location seen before reversing and the unit will resume reading at the immediate point at which the boast is sitting in the water.
  • Page 24 USING THE LCR 4000 OPERATIONAL INSTRUCTIONS The Zoom may be activated at any time (during normal transmitting and receiving or stop action, or reverse), but while learning to use the Zoom feature you might find it easiest to first press the Stop/Resume button to freeze the display. Now you can position the Zoom Range, activate the Zoom, and study the display.
  • Page 25 USING THE LCR 4000 OPERATIONAL INSTRUCTIONS In bottom lock the expanded information always comes onto the screen at the same location. However, as the information moves across the screen and as the bottom contour moves up or down, the displayed information will also move so that you can see the actual bottom contour.
  • Page 26 In order for your LCR to operate well at high speeds, you must have a properly mounted transducer. Please read the transducer mounting procedure carefully. The transducer for the LCR4000 is a l6 just like most standard Humminbird flasher units. Other transducers, such as 32 , cannot be used.

  • Page 32: Maintenance And Warranty

    MAINTENANCE AND WARRANTY MAINTENANCE Your Humminbird fishfinder is designed to provide years of trouble free operation with virtually no maintenance. Follow these simple procedures to ensure your Humminbird continues to deliver top performance. If the unit comes into contact with salt spray simply wipe the affected surfaces with a cloth dampened in fresh water.

  • Page 33: Troubleshooting

    Repairs should be performed only by authorized Humminbird technicians. Many requests for repair received by Humminbird involve units that do not actually reed repair. These units are returned “no problem found.” If you have a problem with your Humminbird, use the following troubleshooting guide before calling Customer Support or sending your unit in for repair.
  • Page 34 4. When in very shallow water, I get gaps in the bottom reading and inconsistent digital depth indication. Your Humminbird fishfinder will work reliably in water 2’ (.6m) or deeper. The depth is measured from the transducer, not necessarily from the surface.
  • Page 35 7. My unit loses power at high speeds. Most Humminbird fishfinders have over-voltage protection that turns the unit off when input voltage exceeds 20 VDC. Some outboard motors do not effectively regulate the power output of the engine's alternator and can produce voltage in excess of 20 volts when running at high RPMs.
