INTRODUCTION
The LMS-350A is a high quality, wide screen sonar with performance that
is second to none in its class. 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
underwaterworldwithhighresolutionanddetail.Thedisplayandkeyboard
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).

technology, this GPS receiver is second to none in it's class.
MOUNTING - Bracket Mount

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

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.

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.

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.

POWER CONNECTIONS
The LMS-350A works from a twelve-volt battery system. For the best
results, attach the power cable directly to the battery. You can attach the
power cable to an accessory or power buss, however you may have
problemswithelectricalinterference. Therefore, it’ssafertogoaheadand
attachthepowercabledirectlytothebattery.Ifthecableistooshort,splice
#18 gauge wire onto it. The power cable has four wires; red, black, green,
and white. Red is the positive lead, black is negative or ground. Make
certaintoattachthein-linefuseholdertotheredleadasclosetothepower
source as possible. For example, if you have to extend the power cable
to the battery or power buss, attach one end of the fuse holder directly to
the battery or power buss. This will protect both the unit and the power
cable in the event of a short. The LMS-350A uses a 3-amp fuse.
IMPORTANT!
Do not use this product without a 3-amp fuse wired into the power cable!
Failure to use a 3-amp fuse will void your warranty.
If you’re installing an optional speed/temperature sensor, read the speed/
temperaturesensor's installationmanualformountinginstructions.Route
the sensor’s cable to the LMS-350's power cable and plug it into the
connector marked “SPEED/TEMP CABLE”

The white wire is for a NMEA interface. The LMS-350A sends data to
another electronic navigation devices through the white wire. It receives
data from a differential (DGPS) beacon receiver through the green wire.
If the white and green wires are not used, tape their ends so that they
cannot short.
To connect a device to the LMS-350's NMEA output (white wire), attach
a shielded, twisted pair cable from the device's NMEA intput to the
white wire on the LMS-350's power cable. Solder the ground conductor
of the twisted pair and the shield to the black wire on the power cable.
Do not connect the shield to the other device. Use the green and black
wires in the same manner to attach a DGPS recevier's output to the
LMS-350's input (green wire). See the other instrument's manual and
the NMEA section in this manual for more information.
TRANSDUCER CONNECTIONS
The LMS-350A has dual frequency capability. It can operate at 50 or
192 kHz, separately, or at the same time. The connection diagram
below shows the proper method to attach the transducers to the LMS-
350A. See the transducer owner’s manual for transducer installation
instructions. If dual frequency (simultaneous) operation is desired, a 50
kHz transducer and the MY-2 transducer adapter cable must be pur-
chased separtately.
See page 18 for more information on dual frequency operation.

OPTIONAL GPS MODULE INSTALLATION
The GPS module can be installed on a flat surface or (with the supplied
adapter) on a pole. Mount the module in an area that guarantees a
clear view of the sky at all times. In order for the module to receive the
signals from the satellites, it must not be obstructed. An ideal location is
on a cabin roof, or deck. The gunnels also make a good location.
Attaching the pole mounting adapter lets you install the module on a
one inch mast. However, for lightning protection, the antenna shouln't
be the highest part of the boat.
Surface Mounting - With Access
If you have access underneath the mounting surface, use the gasket
supplied with the GPS module as a template. Drill four 5.5 mm (7/32")
holes and one 17 mm (11/16") hole for the module's cable. Attach the
cable to the module and pass it down through the hole in the gasket and
the mounting surface. Use 5 mm screws, flat washers, and lock
washers to fasten the GPS module to the mounting surface. Route the
cable to the LMS-350A.

Surface Mounting - Without Access
If you don't have access to the back side of the mounting surface, use
the "cleats" supplied with the LMS-350A. (Note: This is assuming you
can "snake" the module's cable to a location that is accessable. A hole
will still need to be drilled in the mounting surface for the cable.) Using
the gasket as a template, mark and drill the 17 mm (11/16") hole for the
cable. Attach the cable to the module and drop the other end of the
cable through the gasket and down the hole. Place the module on the
gasket. Slide the "cleats" onto each end of the module and (using the
cleats as templates) mark four holes for 5 mm (#10) mounting screws.
Drill the holes, then replace the cleats on the module and fasten them to
the mounting surface with 5 mm (#10) screws. Route the cable to the
LMS-350A.

Pole Mount
First, thread the pole mounting adapter onto the mounting pole or
ratchet base. Align the pole mounting adapter so the module will face
the bow of the boat. Install and tighten the set screw into the pole
mounting adapter and tighten it securely. This should prevent the GPS
module from unscrewing from the pole. Place the gasket onto the pole
mounting adapter. Now attach the cable to the GPS module and pass
the cable through the gasket, pole mounting adapter, and pole. Set the
GPS module on top of the pole mounting adapter and align the four
threaded holes in the module with the holes in the pole mounting
adapter. Using the four stainless steel 5 mm screws and lock washers
supplied with the LMS-350A, attach the pole mounting adapter to the
GPS module. This completes the assembly.

If the pole or mast you're using isn't hollow or if the hole in the middle of
the pole is too small for the connectors, use the cable mounting adapter
supplied with your unit. Thread the cable mounting adapter into the
GPS pole mounting adapter. Then thread the pole into the cable mount-
ing adapter. Route the cable down the outside of the pole.
