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)

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 see Figure 1. However, unlike a flasher, this information is not lost but it 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 USING THE LCRINTRODUCTION 1. Objects at least three inches off the bottom are displayed in red. The bottom and structure attached to the bottom are displayed in black. The electronics in the LCR4-lDand LCR40-ID can separate the bottom from objects at least three inches off the bottom no matter what depth range you are viewing. This means that fish close to the bottom will be easily seen on the LCR see Figure 2. These same fish would be missed on an ordinary display because they would just look like part of the bottom USING THE LCRINTRODUCTION TOTAL SCREEN UPDATE TOTAL SCREEN UPDATEUSING THE LCR What is Total Screen Update?USING THE LCR OPERATIONAL INSTRUCTIONSOPERATIONAL INSTRUCTIONS OPERATIONAL INSTRUCTIONS USING THE LCRPlease read the Theory of Operation in the front of the manual for a detailed explanation of the ID feature.
