NOTES; INTRODUCTION The LMS-150 represents one of the best values in sportlishing sonar today. It rivals, other sonar units costing much more in features and perfo'mance. With its menus, the [MS-iso offers easy-to-use operation at the touch of a buffon. The CLEARVISIONTMscreen shows the underwater world with high resolution and detail. The '[MS-i50 also displaysboat speed, surface water temperature,and distancetravelled (distance. log).
POWER CONNECTIONS NOTES: The LMS-i 5aworks from a twelve-von batterysystem only. Farthebest results,attachthepowercabledirectlytothe battery. You can attach the power cableto an accessoryor power buss, however you may have problemswith electrical interference. Therefore, it'ssaferto go aheadand attach the.power cable directlyto the.battery If the cable is nS long enough.,splice#18 gaugewireonto it. Attach the in-line fuseholdertothe red lead as close to the powersourceas possible..
NOTES: IRE To SPEED/TEMP SENSOR TO bran MODULE TO AUTOPILOT DR OTHER MARINE EOUIPMENPS NMEA INTERFACE Improper. performance can also occur if the antenna is mounted too close to metal objects such as tuna towers. Again, a location that places the Loran assembly in the clear is preferableto one that is high and obstructed. You must purchase an eight foot stainless steel or fiberglass whip antenna:. The threads are standard 3/8-24 for the whip.
SPEED/TEMPERATURE SENSOR INSTALLATION Mount the speed/temp sensor on the boat's transom in a locatien where the flow of water is smoothest. There should be a minimum amountof turbulence and air bubbles in the chosen location. The port (left) side of thetransomis preferred,.however thestarboard(right)side can be used if necessary. Do not mount the speed sensorbehind strakes, ribs, or thru-hullfittings that will disturb the flow of water to the speed sensor.
TRANSDUCER CONNECTIONS The LMS-150 has dual frequency capability. It can operate from 192 kHz or 50 kHz. It will display echoes from either transducer, separately or at the same time in an unique split screen mode. The connection diagram below shows the proper method to attach the transducers to the LMS-15o. Note: If dual frequency operation is desired, a MY-2 TransducerAdapter Cable must be used. See your transducerowner's manual for installation instructions. SINGLE FREQUENCY DUAL FREQUENCY K. 7.

The ADJ Display label lets you adjust the display'scontrastfor thebest viewingangle. Pressing this key gives you the contrast adjust menu. See the Display Contrast section for more information on this feature. After the menus clear, the display appears similar to the one.on the next page. The word "AUTO" in the displays upper left corper indicates the automatic feature is on. A small note symbol net to the "AUTO" indicator means the alarm speaker is enabled.
FREQUENCY SELECT Lowrance offers both 50 and 192 kHz transducers for the [MS-I50. The 192 kHzfrequencytypicallyhas superior target resolution, showing fish, structure, and bottom definition betterthan 50 kHz. However,the 192 kHz doesn't penetratewater as well as 50 kHz, therefore it won't go as deep. Also, 192 kHz cone angles are typically narrowerthan the 50s. You can draw a few conclusions from these statements. 1.
AUTOMATIC When the LMS-150 is first turned on, the Automaticfeature is on. This is shown bythe word "AUTO" at the top of the screen. The Automatic feature adjusts the sensitivity and range so the bottom signal 'always shows in the lower half of the screen. LORAN-C NORTH PACIFIC CHAIN GRI 9990 To turn Automatic off, simply press the AUTO key. The word"MANUAL" appears, showing the unit is in the manual mode. To turn Automaticon, press the AUTO key again.

GRAVLINP lets you distinguish between strong and weak echoes. It "paints" gray on targets that are stronger than a preset value. This allows you to tell the difference between a hard and soft bottom. For example, a soft, muddyor weedy bottom returnsa weaker signal whibh displays with a narrow or no gray line. A hard bottom returns a strong signal which causesa wide gray line. GRAYLINBTh If you have two signals of equal size, one with gray and the other without, the target with gray is the stronger signal.
You can see the change on the screen (both on the menu and on the chart ecord) as you press the keys. After you've made the adjustmeni; pressthe key adjacentto the CLEAR key to erase the menu. RANGE - Automatic When first turned on, the LMS-150 automatically places the bottom signàl.in the lower half of the screen. This is called Auto Ranging and is part of The automatic function. You cannot change the range while the un is in automatic.
To adjust theupperor lower limit, press the key adjacent to the "More" label. The menus. shown below appear. To adjust the upper limit, press the key adjacent to the "Upper Limit" arrow. A ne menu appears: "Enter Upper Limit." Usingthe number keys at the display's left side, enter the desired upper limit. In this example, we used 21 feet. If you make an error, pressthe CLEAR key and start again Now press the ENTER key. The LMS-1 50 changes the upper limit to the new value.
The lower limit is adjustable in the same manner. You can choose any upper limit between zero and 4995 feet. The lower limit can be any rangebetween 5 and 5000 feet. The smallest 'window' or distancebetween the upper and lower limit is five feet.L For example, an upper limit of 21 feet and a lower limit of 51 feet gives a window of 30 feet. Upper and lower limits can be set in various combinations to show windowsfrom the surface to the bottom and anywhere in between.
To switch targets between twice their normal size and four times normat, press the key adjacent to the "2X14X" label. To switch between the split screen zoom and full screen zoom, press the key adjacent to the "SPLIT/FULL" label.
