viii INTRODUC TION Keypad Usage The GPSMAP 235 Sounder’s advanced keypad system is designed to allow for fast, con- venient 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 sounder.
1 GETTING S T AR TED Initialization Initializing the Receiver Before you use your GPSMAP 235 for the first time, you’ll need to “initialize the receiver .” Initialization is the process in which the r eceiver collects satellite data and establishes its (your) present position.
AB Initializing the Receiver (con’t.) The Map Page will appear , prompting you to select your appr oximate present posi- tion with the map cursor . 1. Use the R keypad to move the map cursor to a location close to your present position. If you have difficulty identifying your exact position, use the I key to zoom to a lower map scale.
A B Getting Started T our The GARMIN GPSMAP 235 Sounder is a powerful electronic navigation and depth sounding system that provides detailed chart coverage and convenient con- trol of many advanced featur es right from the screen display .
A B Status Page The Status Page provides a visual r eference of satellite acquisition and receiver status, with a signal strength bar graph and a satellite sky view in the center of the page. Each page of the sounder features an options menu, which gives you access to other functions and features that relate to the specific page you ar e viewing.
5 GETTING S T AR TED Page Sequence/Position Page The satellite Status Page is one of five main pages used in the sounder . All five pages are linked together in a simple chain, which allows you to scr oll through the pages in either direction using the J and Q keys.
6 GETTING S T AR TED Using the GOTO Key AB Marking a Position To mark your present position: 1. Press the M key. The mark position page will appear, with a default three-digit waypoint name, symbol, position, and depth. 2. Use the R keypad to highlight the waypoint name field (001) and press T .
Sounder Page The Sounder Page lets you use the GPSMAP 235 as a fishfinder . The top of the screen contains any of seven selectable data field options, while the middle of the page contains a right-to-left moving sonar image of the water beneath your boat.
Range Modes The unit uses three range modes on the Sounder Page: auto, manual, and win- dow . 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 ,.
Zoom Feature The zoom feature allows you to view a smaller portion of the complete range in greater detail. The zoom feature operates in auto or manual mode. Auto zoom will follow the bottom contour while manual zoom will display the selected depth. For more on the zoom feature, see pages 26-27.
Map Page The Map Page combines digital chartplotting with a user -selectable display of navigation data, and a built-in worldwide database. It will also be the page you use most to create and edit waypoints and r outes. Before we take off on a practice r oute, let’ s take a brief look at its various features and displays.
Using the Map Cursor The cursor is an important tool that can be used to pan to other map locations, mark and edit waypoints and routes, and r eview position data of on-screen navaids and waypoints. T o get a feel for using the Map Page and cursor , try the following exercise: 1.
Going to a Destination GPS is all about marking positions as waypoints and navigating to them using the receiver’ s steering guidance and map displays. W e’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.
Going to a Destination (con’t.) A data field at the top of the page will now display the bearing and distance to the second route waypoint. T o get started, let’ s enter a speed for our vessel, which we can do from the ‘Setup Simulator?’ listing on the map options menu.
Going to a Destination (con’t.) Now that we’ve zoomed in a little closer to our route, we can pan ahead of our vessel with the cursor to review and create on-scr een waypoints and navaids. T ry moving the cursor to select the ‘TOUR3’ waypoint— just use the R keypad to move the cursor as close as possible to the waypoint.
15 GETTING S T AR TED Overview Navigation Page The Navigation Page provides graphic steering guidance to your destination. The bearing (BRG) and distance (DIS) to the destination, with your current course (COG) and speed over ground (SOG) , are displayed at the top of the page, along with a compass tape to indicate your cardinal heading.
16 Navigation Page (con’t.) To adjust the simulated boat speed: 1. Press the UP arrow of the R keypad to increase the speed in 5 knot/kph/mph incre- ments. Press the DOWN arrow to decrease the speed in the same increments. To steer the boat: 1. Press the LEFT or RIGHT arrows of the R keypad.
Active Route Page The active route page shows each waypoint of the active r oute in sequence, with the waypoint name, distance and estimated time enroute to each waypoint displayed. As you navigate the route, the active r oute list will be automatically updated, indicating the next destination waypoint.
Main Menu Page The main menu page’ s eleven submenus are divided into categories by function. Y ou can select a particular submenu by simply highlighting the desired option and pressing T . T o get a feel for how the main menu page works, let’ s clear out the track log we’ve created during our simulated tour .
Status Page The Status Page provides a visual r eference of various receiver functions, including current satellite coverage, receiver operating mode and curr ent receiver accuracy . The status information will give you an idea of what the receiver is doing at any given moment.
AB Receiver Status, EPE and DOP Receiver status is displayed at the top of the page, with the current estimated position error (EPE) and dilution of precision (DOP) to the left of the sky view . DOP is an indication of satellite geometry quality measured on a scale of one to ten (lowest numbers the best, highest numbers the poorest).
