- Page 2 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 water and...
- Page 3 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 4 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 5 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 6 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 7 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 8 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 9 Install the mounting knobs and tighten snugly. The unit can now be swiveled and tilted to any desired position.
- Page 10 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 11 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 12 SPLIT SCREEN OPERATION The LCR 8000's split screen feature will allow you to make sideby-side comparisons. You will be able to split the screen and compare the actual, full depth scale information with three functions (1) zoom, (2) bottom lock or (3) screen memory.
- Page 13 What is Total Screen Update? Total screen update is a unique feature of Humminbird LCR's. 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 14 All this information is being put into memory in much smaller increments (pieces) than is being displayed on the normal full depth 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 OPERATIONAL INSTRUCTIONS FOR LCR 8000 and LCR 8000D The Humminbird LCR 8000 or 8000D will operate fully automatic or manual at the discretion of the operator. At the heart of the LCR are 3 microcomputers which are making thousands of decisions every second.
- Page 16 The LCR 8000 has five depth ranges: 0 to 15 Ft., 0 to 30 Ft., 0 to 60 Ft., 0 to 120 Ft., and 0 to 240 Ft. The LCR 8000D has seven depth ranges: 0 to 30 Ft., 0 to 60 Ft., 0 to 120 Ft.,...
- Page 17 0 to 240 Ft., 0 to 480 Ft., 0 to 960 Ft., and 0 to 1500 Ft. You may manually change the depth range by pressing the depth set button and then either the increase or decrease button. Each time one of the set buttons is depressed the range will change by one setting.
- Page 18 If Display speed or sensitivity is pressed a chirping sound will indicate an incorrect entry. 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. 6.
- Page 19 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 (See Paragraph 4 under Manual Mode).
- Page 20 The information on the left side of the display is an expanded view of the area from the top of the zoom region to the bottom of the zoom region. The exact depth of the top and bottom of the zoom range will be displayed in the upper and lower left corners of the screen.
- Page 21 In bottom lock the bottom will always come onto the screen one third up from the bottom of the display. As the bottom depth changes the expanded view will also change so that the actual bottom contour can be seen. The depth numbers in the upper and lower left corners of the screen will indicate the exact depth of the zoom range.
- Page 22 Memory: By pressing the mode button, memory locations 1 thru 16 will be displayed. The screen memory feature of the LCR 8000 is now on. Refer to Section 12 below for operation of the Screen Memory. Temp: If the optional surface temperature unit is installed with your LCR, by pressing the mode button again, the surface temperature of the water will be displayed.
- Page 23 16 memory location numbers, 1 through 16. By pressing the Memory Select button the memory location number will increase by one. If the Memory Select button is held down the memory location number will advance at a fast rate. Once the memory location number reaches 16 it will go back to 01 and begin counting up again..
- Page 24 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.
