GPS 135 Rev C 8/4/98 4:17 PM Page i INTRODUCTION Warning Warning The GPSMAP 135 Sounder should not be used as a navigational aid or depth sounder to prevent collision, grounding, boat damage, or personal injury. The digital depth displayed is the depth under the back of your boat and not the front. By the time a depth is displayed most of your boat has already passed over that area. We recommend that you operate the boat at very slow speed if you suspect shallow water or submerged objects.

GPS 135 Rev C 8/4/98 4:17 PM Page viii INTRODUCTION Keypad Usage The GPSMAP 135 Sounder’s advanced keypad system is designed to allow for fast, convenient selection of navigation options and data entry. The Getting Started Tour will introduce you to the keypad and provide a ‘hands-on’ lesson in using the GPSMAP 135 Sounder. We strongly encourage you to take the Getting Started tour before using your unit for actual navigation and fishing.
GPS 135 Rev C 8/4/98 4:17 PM Page 1 Intializing the Receiver GETTING STARTED The first time you power up your new GPSMAP 135 Sounder is an important step in getting the best possible GPS performance. The receiver must be given an opportunity to collect satellite data and establish its present position. To ensure proper initialization, the GPSMAP 135 Sounder is shipped from the factory in AutoLocateTM mode, which will allow the receiver to “find itself” anywhere in the world.
GPS 135 Rev C 8/4/98 4:17 PM Page 2 GETTING STARTED Initialization The select initialization window will appear, with the ‘select from map’ option highlighted. 1. Press T to initialize the receiver from the built-in worldwide map. The map page will appear, prompting you to select your approximate present position with the map cursor. 1. Use the R keypad to move the map cursor to a location close to your present position.
GPS 135 Rev C 8/4/98 4:17 PM Page 3 GPSMAP 135 Sounder Getting Started Tour The GARMIN GPSMAP 135 Sounder is a powerful electronic navigation and depth sounding system that provides detailed chart coverage and convenient control of many advanced features right from the screen display. This tour is designed to take you through the basic pages and functions of the system using the simulator mode.
GPS 135 Rev C 8/4/98 4:17 PM Page 4 Status Field GETTING STARTED Horizontal Accuracy Status Page/Simulator Mode Dilution of Precision Satellite Sky View Signal Strength Indicators Status Bar Digital Depth The GPSMAP 135 Sounder’s status page provides a visual reference of satellite acquisition and receiver status, with a signal strength bar graph and a satellite sky view in the center of the page.
GPS 135 Rev C 8/4/98 4:17 PM Page 5 GETTING STARTED Page Sequence/Position Page The satellite status page is one of five main pages used in the GPSMAP 135 Sounder’s system. All five pages are linked together in a simple chain, which allows you to scroll through the pages in either direction using the J and Q keys. To continue the tour, let’s move on to the next page, the position page. Compass Tape To scroll to the next page in sequence: 1. Press the J key.
GPS 135 Rev C 8/4/98 4:17 PM Page 6 To mark your present position: GETTING STARTED 1. Press the M key.

(Note: Items appear on the screen as they pass under your transducer.
GPS 135 Rev C 8/4/98 4:17 PM Page 8 GETTING STARTED Sounder Page The GPSMAP 135 Sounder uses three range modes: auto, manual, and window. Auto mode displays the most information possible while continuously showing the bottom. Manual mode lets you select the displayed depth. Window mode allows you to define a starting depth and length of the range window. You may switch between auto and manual modes by using the R keypad.
GPS 135 Rev C 8/4/98 4:17 PM Page 9 Another useful feature of the GPSMAP 135 Sounder is the sounder zoom, which allows you to instantly “zoom in” to look at a specific portion of the sounder display by using the Z key. The sounder zoom function is divided into four display levels: GETTING STARTED Sounder Page • 2X Split Screen––Shows two reduced-size sonar pictures at the same time. The top half of the display screen shows the complete sonar picture at its original scale.
GPS 135 Rev C 8/4/98 4:17 PM Page 10 Let’s continue the Getting Started Tour with the map page. GETTING STARTED Map Page 1. Press the J key. The GPSMAP 135 Sounder’s map page combines digital chartplotting with a user-selectable display of navigation data and a built-in worldwide database to 64 nm. It will also be the page you use most to create and edit waypoints and routes. Before we take off on our practice route, let’s take a brief look at its various features and displays.
GPS 135 Rev C 8/4/98 4:17 PM Page 11 Using the Map Cursor Working from the map page is a simple process that centers around the use of the cursor. Controlled by the R keypad, the cursor is an important tool that can be used to pan to other map locations, mark and edit waypoints and routes, and review position data of on-screen navaids and waypoints. GETTING STARTED Map Cursor To get a feel for using the map page and using the cursor, try the following exercise: 1.
GPS 135 Rev C 8/4/98 4:17 PM Page 12 Going to a Destination GETTING STARTED Using the GOTO Function GPS is all about marking positions as waypoints and navigating to them using the receiver’s steering guidance and map displays. We’ve already seen how to use the M key to store our present position, so it’s time to move on to the fun part— going to a destination.
GPS 135 Rev C 8/4/98 4:17 PM Page 13 A data field at the top of the page will now display the bearing and distance to the second route waypoint. To get started, let’s enter a speed for our vessel, which we can do from the ‘Setup Simulator?’ listing on the options page.
