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
transducer connector up through the hole. If you are installing two units, both transducer connectors
can be pulled through this 1 1/8” inch hole. Next, push the power cable wires down through the hole. A
hole cover has been provided which will dress and hold the wires. Install the hole cover after
determining the necessary wire length from the hole.
The power cable has a red lead to the positive (+) post and the black lead to the negative (-) post.
Install a 1 amp fuse between the red cable and positive post of your 12-volt battery.
If a fuse panel is available, we recommend wiring the power cable into the fuse panel. Note: The LCR
must be fused separately from any other accessory.
Your Angle-Lock connectors can only be plugged in one way. Position the connector so the letter P or T
can be read and the 90 degree bend is pointed downward. Push the connector in as far as it will go.
Turn the positive locking ring as far as it will go clockwise until you feel it lock. locking ring as far as it
will go clockwise until you feel it lock. Your connector is now locked into place.
Note: For easy access to the connectors, simply loosen the mounting knobs and tilt your LCR forward.
The connectors are now in full view and easy to plug or unplug.
TOTAL SCREEN UPDATE
What is Total Screen Update?
Total Screen Update is a unique feature of the LCR3000. It will allow you when changing depth
scales, to totally change or update the screen to the new depth scale. It will also allow you to zoom in
and look at information in much finer detail even after you’ve already gone over the area.
How does Total Screen Update Work?
Inside the LCR3000 are memory devices, which can store approximately 60,000 bits of
information. Automatically, while you’re operating the LCR3000, the computer is putting information
into the LCR’s memory. This stored information as all the data from zero to 180 feet.
All this information (from 0 to 480 ft.) is being recorded to no matter what depth-scale you are
using. Also, the information is being put into memory in much smaller increments (pieces) than is being
