Summary of Contents for Humminbird LCR 3000

  • 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 is 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 the LCR, we suggest you follow the instructions set forth in this manual.
  • Page 3 Please read the transducer mounting procedure carefully. 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 4 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 5 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 6 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 7 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 8 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.
  • Page 9 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 10 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.

    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 13 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.
  • Page 14 displayed on the normal 0 to 30, 0 to 60, 0 to 120, 0 to 240, or 0 to 480 foot scales. For example, on the 0 to 60 foot scale each dot is equal to one foot of depth, but the computer is putting information into memory such that each dot equals 3 inches.
  • Page 15 the next shallower scale. You may manually change the range by depressing the depth “set” button. Each time this button is depressed, the range is decreased by one setting. Note: Should you attempt to change to a depth scale which is less than the actual bottom depth, the computer will automatically change the depth scale back to the proper position.
  • Page 16 the maximum or minimum setting is achieved, the unit will make a “Chirping” sound indication a limit has been reached. 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.
  • Page 17 If they are pressed, a chirping sound will indicate that these functions cannot be changed while display is stopped. All other functions, such as Zoom and Depth Scales, are active with the display stopped. When the “Stop/Resume” button is pressed again the unit will resume reading at the immediate point at which the boat is sitting in the water.
  • Page 18 8. Zoom: You will find the Zoom feature if the LCR3000 to be a very valuable too. The Zoom Range is controlled by the set and (upper arrow sign) or (lower arrow sign) Buttons. Each time one of these buttons is depressed to zoom regions will move on division.
  • Page 19 activated. You will notice that the letter Z appears in the lower right hand corner 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 tip of the Zoom Range to the bottom of the Zoom Range.
  • Page 20 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 is used 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.

  • Page 21: Troubleshooting

    LEARNING TO USE YOUR LCR: Step 1 After making sure that you are in water deeper than four feet, turn your LCR on by pushing the “On” button. The LCR’s computer will automatically adjust the sensitivity and depth scale so that in about one second you will see images appear on the right side of the display and moving to the left.
  • Page 22 If at high speeds the bottom return is not continuous or there are gaps in the bottom, then the transducer installation or location is such that air is going under the transducer face. Remember that a transducer cannot work properly through air or air bubbles in the water. The Inside Hull Mount and Kick-Up Mount are best for high speed operation.
  • Page 25 It’s the creation of a new generation- Humminbird’s LCR 4000.
