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. 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 w

by rotating up out of the metal spring bracket without harming the transducer, or your boat. The transducer can be re-engaged by simply rotating the transducer down and snapping it back in place. (See Figure A) 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

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. (See Figure C) Step 2. BRACKET INSTALLATION (Fiberglass Boats)- If your boat h

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. Be sure to align the holes so that they are centered vertically in the three slots found in the bracket. It is important to use a silicone sealant between the screwhead and bracket in or

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. (See Figure G) Step 5 ANGLE ALLIGHMENT- Set the transducer angle so that it is parallel with the bottom of the boat hull. Once p

wrench provided. The screws are visible through the access holes on each side of the metal bracket. Check to make sure the transducer main body is rigidly fastened to the pivot. (See Figure H) Step 6 CHECK POSITION OF TRANSDUCER- At this point, check to see that the bottom of the transducer is a minimum of ¼” below the bottom of the transom. (However, as noted in STEP 2, the top of the transducer cannot fall below the bottom of the transom). If it is not, remove the transducer assem

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. 9. Coat the bottom of the transducer with epoxy, then put it in the center of the puddle and push down on the transducer while moving it around in a circular mot

OTHER MOUNTING OPTIONS 1. The LCR gimbal bracket can also be mounted on the SM-4, quick disconnect swivel mount. 2. The LCR gimbal bracket can also be mounted directly to the dash without the swivel mount, however, this method is not recommended since the unit cannot be rotated. INSTALLING THE CABLES Your LCR comes equipped with Humminbird’s new A

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. 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 transduc

THEORY OF OPERATION Your Humminbird LCR works on the basic principal 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. The speed of the ultrasonic signal traveling through the water is approximately 4800 feet per second. The signal travels through the water until it strikes an object or the bottom. At this instant it is reflected back, pi

When zoom is activated, for example, the left half of the screen shows the expanded information while the right half shows the full depth scale information. No other depth sounder can give you this kind of comparative advantage. The zoom range can be moved up or down to search out any area, allowing you to compare on one screen both the full scale view and the expanded up-close information. Even the depths of the upper and lower part of the zoom region are digitally displayed for prec

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. If after reading this, you don't understand now Total Screen Update works, don't worry. The important thing is that you understand how to use Total Screen Update. Read on.... How To Us

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. With the LCR'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 LCR like an expert. It is suggested that you familiarize yours

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. Note: Should you attempt to change to a depth range which is less than the actual bottom depth, the computer will automatically change the depth range back to the proper position. For example, if you are in 40 feet of water an

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. Display Speed Set: The LCR has 8 display speed settings. When the unit is turned on the display will be advancing at a medium speed. To increase the display speed, depress the Speed Set and or hold it down to change rapidly. An audible sound is heard

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). To once again activate the automatic mode, depress the Sensitivity Auto "On/Off" button.

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. As the zoom range is moved up or down these numbers will change to indicate the exact setting of the zoom range. These depth indicators will be very useful in pinpointing the exact depth of fish or structure. The zoom
