  • Page 2: Theory Of Operation

    Before attempting to install or operate your Humminbird LCR it is recommended that you read the operations manual thoroughly. The LCR has a number of special features not found on any other depth sounder. Therefore, to completely understand all the features we suggest you follow the instructions in this manual.

  • Page 3: Split Screen Operation

    The display technology used on the LCR4x6 has been pioneered by Humminbird. The display uses Advanced Super Twist Liquid Crystal Technology for the best contrast, widest viewing angle and extreme high and low temperature operation.
  • Page 5 The detailed operation of each of these functions is explained later in this manual. TOTAL SCREEN UPDATE Total Screen Update was invented by Humminbird engineers. You will find this unique feature very useful and beneficial. It will allow you, when changing depth scales, for example, to totally change the entire screen to the new depth scale.
  • Page 6 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.
  • Page 7 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. The transducer will absorb the blow of any obstruction by rotating up out of the metal spring bracket without harming the transducer, or your boat.
  • Page 8 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 9 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.
  • Page 10 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 11 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”...
  • Page 12 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 13 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.
  • Page 14 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.

    that in about one second you will see images appear on the right side of the display and moving to the left. TROUBLE SHOOTING: If nothing happens when the “Power” button is pushed, check your electrical connections and fuse. Also check that the red wire on the power cable is connected to the positive battery terminal and that the black wire is connected to the negative battery terminal.
  • Page 19 SELECTING AND OPERATING THE FUNCTIONS Pressing the button will result in one of eight different menus of the LCR4x6 functions to be displayed on the screen. Each time the button is pressed a different menu will appear. After the eighth different menu is displayed, the first menu will be displayed again. Unless the button is pressed, no function will be changed.
  • Page 20 THINGS TO KNOW ABOUT AUTOMATIC AND MANUAL OPERATION A. When the LCR is turned on the unit is in the automatic mode. This is indicated on the menu and in the lower left area of the screen. In the Automatic Mode the sensitivity Is continuously adjusted automatically, the correct depth range is automatically selected and the area below the bottom return is blackened out making the bottom easy to see.

  • Page 21: Depth Range

    E. In the Manual Mode it is possible to have the sensitivity set too high such that reflection from suspended matter or air bubbles will begin to black out the display. DEPTH RANGE...

  • Page 22: Bottom Alarm

    THINGS TO KNOW ABOUT DEPTH RANGE A. In the automatic mode the proper depth range is found as soon as the unit is turned on. B. As you move into deeper water and the bottom goes off the screen, the next deeper depth range will automatically be activated.

  • Page 23: Fish Alarm

    THINGS TO KNOW ABOUT BOTTOM ALARM A. The alarm setting is shown digitally (in numbers) on the menu and graphically ( by the vertical bar ) on the right side of the display. It is set at 5 feet when the unit is first turned on. B.
  • Page 24 THINGS TO KNOW ABOUT FISH ALARM A. The Fish Alarm will give a short alarm sound when a return is detected between the boat and 3 inches from the bottom. It will not alarm on the bottom. B. When the Fish Alarm is on it is indicated on the menu and also on the right side of the display by the word “FISH”.
  • Page 25 THINGS TO KNOW ABOUT ZOOM A. When Zoom is turned on, the screen will automatically split showing the full depth scale information on the right and the expanded view corresponding to the portion of the Zoom Cursor on the left (see Figure 2). B.
  • Page 26 F. Zoom may be activated at any time. While learning to use Zoom it may be easier to press the button to freeze the display after positioning the Zoom Cursor. This will give you time to study the display. NOTE: If the display is stopped, the screen will not update (change) until the button is pressed again.

  • Page 29 CARING FOR YOUR LCR: Since your Humminbird 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. When cleaning the lens, it is suggested you use a chamois cloth and a non-abrasive cleaner such as Windex Do not wipe while dirt or other gritty material is on the lens.
  • Page 30 Brush and standing timber will appear as shown in the display above. The speed of the boat and display sweep speed will have a large effect on the way this information is displayed. For example, at a slow boat speed and a fast sweep speed the standing timber will appear wider. At a fast boat speed and a slow sweep speed some of the information will be missed.
  • Page 31 With Bottom Lock the wreck and the fish are clearly displayed on the left side of the screen which shows an expanded view 20 feet up from the bottom (screen is from 142 feet to 172 feet).
  • Page 32 Thermocline is a temperature change at a certain depth in the water.
