LMS-350A INSTALLATION AND OPERATION INSTRUCTIONS IMPORTANT! YOU MUST HAVE THE OPTIONAL LGC-1 GPS MODULE ATTACHED TO THE LMS-350A TO USE THE POSITION AND NAVIGATION FEATURES ON THIS PRODUCT. WARNING! USE THIS PRODUCT ONLY AS AN AID TO NAVIGATION. A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION The LGC-1 GPS receiver, (like all GPS navigation equipment) will show the shortest, most direct path to a waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only take advantage of all available navigation tools when travelling to a waypoint, but will also visually check to make certain a clear, safe path to the waypoint is always available. NOTICE! As of this writing, the Department of Defense (DOD) has not declared the GPS navigation system operational. The system is still in a testing phase. Satellites can be turned off or accuracy can be degraded at will by the system operators. Remember that the LMS-350A, or any GPS receiver is only as accurate as the system it's using.

Using menu features and "soft-key" operation, the LMS-350A is also one of the easiest-to-use sonars that Lowrance has ever built. The wide "ClearVision" screen shows the underwater world with high resolution and detail. The display and keyboard are also lighted for night operation. The LMS-350A also has digital depth, boat speed, surface water temperature, and distance travelled (log) displays (requires an optional ST-T speed/temperature sensor). If you purchase and install a LGC-1 GPS module, the LMS-350A can show position and navigation information. Utilizing Rockwell's NavCoreV technology, this GPS receiver is second to none in it's class. MOUNTING - Bracket Mount The LMS-350A can be mounted on it's gimbal bracket or in-dash mounted. Brackets are supplied for both configurations, however if the dash is thicker than 1/2", a special bracket will have to be purchased to mount the unit in the dash. You can install the LMS-350A on its bracket in any convenient location, provided there is clearance behind the unit when it is tilted for the best viewing angle. Holes in the bracket base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panels to secure the mounting hardware. Make certain there is enough room behind the unit to attach the power and transducer cables. FRONT SLOT BREAK OUT SLOT You will need to drill a hole in the dash for the power and transducer cables. The smallest hole that will pass one power or transducer plug is one inch. After the hole is drilled, pass the transducer connector up through the hole first, then pass the power cable down through it. After the cables have been routed, fill the hole with a good marine sealing compound. Offset the bracket to cover the hole. Route the power cable through the slot and break out one of the other slots in the bracket for the transducer cable. 1 IN-DASH MOUNTING The LMS-350A can be installed in the dash with the supplied hardware if the dash is 1/2" thick or less. Determining the dash thickness can be difficult, however, if you remove a gauge from the dash, you can easilly measure the thickness. Try this in an area that's close to the location that you wish to install the unit, since the thickness can vary significantly in some boats. Make certain there is clearance behind the dash for the unit and there is enough room to tighten the bolts on both sides of the unit. 7.625" DASH CUTOUT .400" radius (4 places) Once you've determined the location for the unit, cut the hole according to the drawing shown above. Measure carefully before cutting! After cutting the dash, place the gasket supplied with the LMS-350A around the unit and place the unit in the hole. Supplied with the LMS-350A are rubber pads, bolts, washers, and cam clamps to attach the LMS-350A to the dash. Peel the adhesive backing off the rubber pads and place one on each side of the LMS-350A in the location where the cam clamp will touch the back side of the dash. Using the hardware supplied with the unit, attach the LMS-350A to the dash. Make certain that the cam clamp on the left side of the unit is pointing down and the cam clamp on the right side of the unit is pointing up before you start tightening the bolts.
