  • Page 3: Transducer Exchange

    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...

  • 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 Step 2. BRACKET INSTALLATION (Aluminum Boats)- To install the metal bracket on an 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.
  • Page 6 To install the metal bracket on a fiberglass boat, locate the template on the transom in the same manner as for an aluminum boat. (See Figure C) 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.
  • 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.

  • Page 8: Inside The Hull Installation

    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.

  • Page 10: Control Head Installation

    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

    Humminbird LCR. THEORY OF OPERATION Your Humminbird LCR works on the basic principals of sonar. An electronic signal is generated within the control head of the unit. When coupled to the transducer, this signal is converted to an ultrasonic signal and is transmitted toward the bottom.
  • Page 15 USING THE LCR INTRODUCTION The reading at the far right hand position of the display illustrates that which is being passed over at that time. If you are familiar with a flasher unit, you might think of the information coming on the right side of the screen as the information that would be seen at one instant on a flasher (see Figure 1).
  • Page 16 USING THE LCR INTRODUCTION TheLCR4-ID and LCR40-ID use a special and very unique liquid crystal display. Ordinary LCD's have two colors-black and white. The black color, as was explained earlier, is made by blocking the light that comes into the display. The LCR4-ID and LCR40ID add a third color, red, by using a second layer on the display.

  • Page 17: Using The Lcr 4000

    TOTAL SCREEN UPDATE® What is Total Screen Update? Total screen update is a unique feature of Humminbird LCRs. It will allow you, when changing depth scales, to totally change or update the screen to the new depth scale. It will allow you to zoom in and look at information in much finer detail even after you’ve already gone over the area.

  • Page 18: Operational Instructions

    The operation of the zoom function is explained in a later section. OPERATIONAL INSTRUCTIONS The Humminbird LCR will operate fully automatic or manual at the discretion of the operator. At the heart of the LCR are 2 microcomputers which make thousands of decisions every second.
  • Page 19 USING THE LCR OPERATIONAL INSTRUCTIONS Please read the Theory of Operation in the front of the manual for a detailed explanation of the ID feature. Below are some tips to help you use this advanced ID feature: A. The bottom and anything attached to the bottom are displayed in black. B.
  • Page 20 USING THE LCR OPERATIONAL INSTRUCTIONS Automatic or Manual Mode Automatic Mode- Each time the unit is turned on, the automatic feature is on. In the automatic mode the sensitivity is adjusted automatically to give a good return and the correct depth range is selected. The word Auto will appear in the lower left corner of the display any time the unit is in the automatic mode.
  • Page 21 USING THE LCR OPERATIONAL INSTRUCTIONS Also, in the manual mode everything below the bottom is no longer blacked out, therefore a second return or double echo can be displayed if desired. (See figure 15). Also, the hardness of the bottom can be determined by the thickness of the bottom return.
  • Page 22 word Zoom appears in the lower part of the display, indicating that the Zoom is on. You will also notice that the entire screen has been changed to show an expanded view of the area from the top of the Zoom Range to the bottom of the Zoom Range. The LCR'S Total Screen Update feature allows you to zoom in on an area even after you have passed over it.
  • Page 23 USING THE LCR 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 24 USING THE LCR OPERATIONAL INSTRUCTIONS Automatic Mode: In the automatic mode a continuous alarm will sound only when the bottom depth is equal to or less than the alarm setting. Fish entering the alarm range will not trigger the alarm unless of course the fish alarm is on. Manual Mode: In the Manual Mode either the bottom or fish can trigger the alarm.
  • Page 25 USING THE LCR OPERATIONAL INSTRUCTIONS 9. Depth: In the automatic mode, the proper depth range is found as soon as the unit is turned on. As you move into deeper water and the bottom goes off the screen the next deeper depth range will automatically be activated. Also, as you move into shallower water the depth range will automatically change to the next smaller scale.
  • 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 LCR is a l6 just like most standard Humminbird flasher units. Other transducers, such as 32 , cannot be used.
  • Page 27 USING THE LCR ADDITIONAL INFORMATION CARING FOR YOUR LCR Since your Humninbird LCR is completely waterproof, it can be cleaned with soap and water or hosed off after salt water use with no fear of damage to the unit or its electronics.

  • Page 33: 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 34: 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 35 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 36 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.
