THEORY OF OPERATION
Your Humminbird LCR works on the basic principal of sonar. An electric signal is generated within the control head of the unit. When coupled to the to, 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 , picked up by the transducer, reconverted to an electronic signal and is recorded on the display of the LCR.
The reading at the far right hand position of the display illustrates that which is being passed over at that time. If you are familiar with a flasher unit, you might think of the information coming on the right side of the screen as the information that would be seen at one instant on a flasher. However, unlike a flasher, this information is not lost but is shifted or moved to the left as new information comes on. Therefore, the information is retained until it disappears from the left hand position of the display.
The display used on the LCR is a Liquid Crystal Display. The material in the display is a liquid that can be aligned such that it either “blocks” light or it lets light pass through. This “blocking” of light is what makes the black dots on the screen.
Since the LCR’s display depends on light passing through it to make the images, increasing the light source will make it easier to use. This is why your LCR can be seen so well in direct sunlight. You will also not ice that the display can be seen better at certain angles. The LCR mounting has been designed for tilting and pivoting so that you can easily maintain a good angle for viewing. Another characteristic of an LCD display is that you may find that some polarized glasses might affect the view by causing a rainbow prism to appear. This condition can possibly be improved by a slight adjustment in tilt.
The high visibility readout of the LCR allows you to see fish, bottom contour and underwater structure. The LCR is designed to operate with a standard 16-degree transducer included with the unit. Other
transducers, such as 32 degrees, cannot be used. In order for your LCR to operate well at high speeds, you must have a properly mounted transducer. 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.
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. 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 type of installation. You cannot shoot through the hull of an aluminum boat.
C. Trolling motor Mount- This type of transducer is not supplied with your LCR. It is designed to mount
on the foot of a trolling motor. You may exchange your un-used high speed transducer for a trolling motor transducer. Call the Humminbird Customer Service Department.
D. Bronz Thru-Hull Mount- This transducer is not supplied with your LCR but for an additional cost you
may exchange your un-used high speed transducer for a bronz thru-hull. The bronz thru-hull transducer has a threaded stem which installs through a hole drilled in the boat hull, leaving the housing exposed under the boat. Th is type of installation must be used for many boats with in­board engines, because there is no suitable location on the transom away from the noise and turbulence created by the prop. A bronz thru-hull transducer should be installed by qualified personnel only. The LCR will operate well at high speeds with a properly mounted transducer. Remember, a transducer will not work transmitting through air or through air bubbles.
1. TRANSOM MOUNTING PROCEEDURE
Step 1. MOUNTING LOCATION- It is important that the transducer be mounted on the transom where water flow is in constant contact with the transducer. You may wish to observe the rear of the boat while it is moving through the water to determine the best mounting location.
Step 2. BRACKET INSTALLATION (Aluminum Boats)- To install the metal bracket on an aluminum boat locate the template on the transom between rows of rivets, or ribs that are on the bottom of the boat. Align the template so that the bottom corner of the template nearest the center of the transom is on the bottom edge of the transom.
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 has a stepped transom located below and under the main transom, the compact transducer design allows mounting in this area. This mounting location is recommended for good reading at very high speeds. (See Figure D)
To install the metal bracket on a fiberglass boat, locate the template on the transom in the same manner as for an aluminum boat. (See Figure C)
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 order to prevent leaking.
Step 3. TRANSDUCER PIVOT ASSEMBLY - Assemble the pivot to the transducer main body using the two ¼”x5/8” allen head screws, two 3/8” tooth washers and two, ¼” square nuts. Make sure the tooth washers are sandwiched between the transducer main body and the pivot. The square nuts are trapped inside the pivot and will not rotate as the allen head screws are tightened. HOWEVER, DO NOT TIGHTEN AT THIS POINT. (See Figure F)
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 O­ring 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 proper alignment is achieved, tighten the two allen head screws using the 5/32” allen wrench
