  • Page 14: How Lms-320 Gps Works

    First, think of your LMS-320 as a small but powerful computer. (But don't worry — we made the LMS-320 series easy to use, so you don't need to be a computer expert to find your way!) The unit includes a keypad and a screen with menus so you can tell LMS-320 what to do.
  • Page 15 LMS-320 has one more thing in common with a personal computer. Just as computers have a floppy disk drive for storing and exchanging files, the LMS-320 has a slot for an MMC (MultiMedia Card) or SDC (Secure Digital card) flash memory card. These solid-state memory de- vices are about the size of a postage stamp, but can hold data ranging from 8 MB to 128 MB in size.

  • Page 16: Introduction To Gps And Waas

    Introduction to GPS and WAAS Well, now you know the basics of how LMS-320 does its work. You might be ready to jump ahead to Section 2, Installation & Accessories, on page 13, so you can mount your unit and plug in the power. Or you might want to see how our text formatting makes the manual tutorials easy to skim.
  • Page 17 These signals can be easily blocked by trees, buildings, an automobile roof, even your body. Like most GPS receivers, LMS-320 doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the sat- ellites to calculate a position.

  • Page 18: How To Use This Manual: Typographical Conventions

    First, the U.S. government has not completed construction of the WAAS system, so it is not yet fully operational. The ground stations are in place, but only a few of the needed WAAS satellites have been launched. WAAS can boost the accuracy of land GPS navigation, but the system is designed for aircraft.

    ducer does "kick-up," the bracket can easily be pushed back into place without tools. Read these instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed.
  • Page 23 at speeds faster than 35 mph. Typically, a good location on alumi- num boats is between the ribs closest to the engine. 2. The transducer should be installed with its face pointing straight down, if possible. 3. If the transducer is mounted on the transom, make sure it doesn't inter- fere with the trailer or hauling of the boat.

  • Page 24: Transom Transducer Assembly And Mounting

    Transom Transducer centerline Hull bottom Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be coming out of the water as you cross waves or wakes.
  • Page 25 The following instructions sometimes vary depending on the mounting bracket that came with your transducer. Single-frequency Skimmers come with a one-piece stainless steel bracket, while dual-frequency Skimmers come with a two-piece plastic mounting bracket. Use the set of instructions that fits your model. 1.

One-piece bracket: Slide the transducer between the two ratch- ets. Temporarily slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground.
  • Page 27 B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily slide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground.
  • Page 28 B. Two-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the figure in step 2B. Don't tighten the lock nut at this time. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground.
  • Page 29 Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing them with the caulking compound. Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn.

    7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the trans- ducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull!

This information is calculated from an optional water speed sensor, not the GPS.

  • Page 85: Sensitivity & Auto Sensitivity

    NOTE: If knowing the exact depth of water beneath the keel is less impor- tant, you can calibrate the depth indicators so that they show the ac- tual water depth from surface to bottom. To do this, first measure the distance from the face of the transducer up to the surface (the water line on the boat).
  • Page 86 can adjust sensitivity up to 100 percent but the unit will limit your minimum setting. In auto, the unit will continue to make small ad- justments, allowing for the setting you selected. In manual mode, you have complete control over sensitivity, with the ability to set it anywhere from zero to 100 percent.

It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual.
  • Page 100 This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. 3. The water may be deeper than the sonar's ability to find the bottom. If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display will flash continuously.
  • Page 101 NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonar's display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit to operate erratically, or not at all. To eliminate or minimize the effects of electrical noise, first try to determine the cause.
