CAUTION
This GPS receiver
(likeall GPSnavigation equipment)
will showthe shortest, mostdirectpath to awaypoint. It
providesnavigation datatothe waypoint, regardless of
obstructions. Therefore, the prudent navigator will not
onlytakeadvantage of all available navigationtools,but
will alsovisuallycheckto make certaina clear, safe
pathto a waypoint
isalwaysavailable.
WARNING!
USE THISGPS RECEIVER ONLYASAN AIDTO
NAVIGATION. ACAREFULNAVIGATOR NEVER
RELIES ON ONLYONE METHOD TO OBTAIN
POSITION INFORMATION.
CAUTION
Asofthis writing, the Department of Defense (DOD) has
not declaredthe OPS navigation system asoperational.
Thesystem isstillin atestingphase. Satellites can be
turnedofforaccuracy degraded at will bythesystem
operators. Remember thatthe LMS-1

INTRODUCTION
The LMS-15OGPS represents one ofthebest values in sportfishing
sonar
today. It rivals othersonar unitscostingmuchmorein features
and performance. With its menus, the LMS-15OGPS offers easy-to-
useoperationatthetouchof a button. The GLEARVISIONTMscreen
shows theunderwaterworldwithhighresolution anddetail. TheLMS-
1SOGPS also displays boat speed, surface water temperature,and
distancetravelled (distance log). The GPS module gives you a full
featured GPS receiver, complete withplotterand waypoint navigation
capabilities.
Although the LMS-1SOGPShasmany
featuresandfunctions, the"soft

MOUNTING
You caninstalltheLMS-1SOGPSin anyconvenient
location, provided
thereisclearancebehind theunit. Place itinposition firstandtiltitfor

canusewoodscrewsorthrough-bolts toattachthebrackettotheboat.
You mayneedto placea pieceofplywood on thebackofthin fiber-
glasspanels
to secure themounting hardware. Makecertainthereis
enough

GPSMODULE INSTALLATION
TheGPSmodule canbeinstalled onaflat surface or(with the
supplied
adapter)on a pole. Mount themodule in an areathat guarantees a
clearviewoftheskyatalltimes. Inorderforthemodule toreceive the
signalsfromthesatellites, itmustnotbeobstructed. Anideallocation
ison acabinroof, ordeck. Thegunnelsalso make a good location.
Attaching thepole mounting adapterlets you installthe module on a
one inch mast. A highlocationis preferred. However, for lightning
protection, theantenna shouldn't bethehighest partoftheboat.

SPEED/TEMPERATURE SENSOR INSTALLATION
Mount the speed/temp sensor on the boat's transom in a location
wheretheflow of water is smoothest. There shouldbe a minimum
amountofturbulenceandairbubbles inthechosenlocation. Theport
(left)sideofthetransom ispreferred, howeverthestarboard(right) side
can be used if necessary. Do not mountthe speed sensor behind
strakes, ribs,orthru-hull fittings that
willdisturb theflowofwatertothe
