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 followin g before installing your transducer.
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 sn apping it back in place.
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 b oats it may be necessary to use a wood back - up plate.
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) Mar k 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.
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.
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.
7. Remove the water and transducer and clean the marked area and the bott om 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.
Install the mounting knobs and tighten snugly. The unit can now be swiveled and tilted to any desired positi on..
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 sinc e the unit cannot be rotated.
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”.
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, thi s signal is converted to an ultrasonic signal and is transmitted toward the bottom.
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.
All this information is being put into memory in much smaller increments (pieces) than is being displayed on the normal full depth scale s. 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.
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.
A Depth range. D Zoom Range. B Display Sweep Speed. E Alarm Depth Setting. C Manual Sensitivity Level. You should notice that each of these buttons are light gray indicating that they are used with the A and * buttons.
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 pre ssing 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.
If Display speed or sensitivity is pressed a chirping sound will indicate an incorrect entry. When the Stop/Resume button is pres sed 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.
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).
The information on the left side of the display is an expanded view of the area f rom 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.
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.
adjusted up or dow n by pressing the depth set button and the increase* or decrease mV button. When the increase or decrease button is pressed once, the alarm setting will change one division. If the button is held down the setting will move as long as the button is held dow n.
16 memory location numbers, 1 t hrough 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.
screen will not erase it from memory. Yo u can recall a screen over and over without losing it. The only way to lose a screen is to store a new screen in its place. 2. Store: - Storing a screen in memory is very easy. After selecting the desired memory location, simply press either the Store L (left ) or Store R (right) button.
side of the display and moving to the left. The small gap in the zero line allows you to see movement on the display even when the bottom is not changing. TROUBLE SHOOTING: If nothing ha ppens when the "On" button is pushed, check your electrical connections and fuse.
Notice the Fish Alarm indication on the screen. Any fish (or objects not on the bottom) will trigger a short fish alarm sound indication. Step 6 Press the Auto Sensitivity On/Off button to change to the manual mode. Notice that the word AUTO in the lo wer left corner of the display has gone off.
Step 4 Now go to Memory Location 2 by pressing the Memory Select Button. Recall Screen 2 by pre ssing the Recall Button. Pre - programmed screens 4 through 9 are shown in Figures 1, 22 and 24. Screens 10 through 13 have been pre - programmed just for fun, screens 15 and 16 are actual readings from Lake Eufaula.
With bottom lock the wreck and fish are clearly displayed on the left side of the screen which shows an expanded view 40 feet up from the bottom (screen is from 112 feet to 172 feet).
Thermocline is a temperature change at a certain depth in the water. In some conditions the sonar waves will actually reflect or bounce off this temperature change and therefore it will be displayed on the LCR as shown above.
The surface temperature gauge is a valuable fishing and boating aid. It will measure water temperature in one - tenth of degrees and display the reading on the LCR screen. The probe and computer controlled electronics have been designed for an accurate indication and an extremely fast response time.
