The GPS receiver should only need to be initialized the first time the unit is used, or if it has been stored several months. The GPS 72 stores orbital data for each satellite in an Almanac. The orbital data is supplied in the satellite signals. Each time the unit is used, the Almanac is updated. This is how the GPS 72 knows which satellites to search for. If you do not use your GPS for several months, or move the unit several hundred miles between uses, the Almanac can become "cold", that is to say that the orbital information is no longer valid. If the Almanac is "cold", your unit may have trouble locking on to satellite signals. If the unit is unable to receive enough satellite signals to determine its location, it will display an options menu. Initializing the GPS Receiver: 1. With fresh batteries installed, take the unit outside where a clear 360° view of the sky can be obtained. 2. Turn the unit on and hold it in front of you with the top of the unit tilted upward. Follow the screen prompts, pressing PAGE to display the GPS Information Page. 3. The initialization process is automatic. It should take the GPS 72 no longer than five minutes to acquire enough satellite signals to become operational. When the unit is able to navigate, it will display either 2D GPS Location or 3D GPS Location in the Receiver Status Field. Introduction Reference Initializing the GPS Receiver Ready to Navigate 7 Initialization Options Introduction Reference Initializing the GPS Receiver If the GPS 72 is unable to determine its location, an options menu will be displayed. Depending on the situation, select an option to help the unit acquire satellites. To select an option, place the highlight over the option then press ENTER. Start Simulator -- The Simulator can be used when you are indoors and the GPS is unable to locate satellites. When you select `Simulator', the GPS receiver is turned off saving battery power. New Location -- If you have moved the unit to another state, province, or country, and you are having trouble locking onto satellite signals select `New Location'. When you select `New Location', another menu will be displayed. This menu contains the options `Automatic' or `Use Map'. If you select `Automatic' the unit will switch to the AutoLocate mode and begin searching for satellites. If you select `Use Map' you can use the Pointer on the Map Page to select your approximate location and the unit will continue to acquire satellites normally. `Automatic' may take longer to acquire satellites. Stored w/o Batteries -- If you have stored the unit without batteries the date stored in the GPS may be incorrect. To check the date, highlight `Stored w/o Batteries' and verify the date displayed. If the date is incorrect, select `Stored w/o Batteries' to search for satellites. Continue Acquiring -- Select this option if you are in an area where the satellite signals are being temporarily blocked. Initialization Options 8 GPS Information Page The GPS Information Page displays your speed, elevation, the estimated accuracy, receiver status, satellite locations, satellite signal strength, the date, time and the GPS receiver's current location. Speed, Elevation and Estimated Accuracy Introduction Reference GPS Information Page When the GPS is receiving at least three satellite signals, it will provide you with the current GPS Speed and the estimated Accuracy of the GPS Location. The GPS must be receiving at least four satellite signals to report the Elevation. Current GPS Receiver Status Data Fields The current status of the GPS receiver will always be displayed. Autolocate -- Forces the receiver to search for each satellite individually. Acquiring Satellites -- The receiver will be in this mode when the unit is turned on. The receiver will remain in this mode until it has acquired at least 3 satellite signals. 2D GPS Location -- Indicates that the receiver is only using three satellite signals. When a 2D GPS Location is achieved, the GPS will display your current position but is incapable of providing an altitude reading. 3D GPS Location -- Indicates the receiver is currently using at least four satellite signals and is capable of providing your current position and altitude. 2D Differential Location -- Indicates the receiver is using DGPS or WAAS differential data on three satellites. A "D" will be displayed in or above the indicator bar for each differentially corrected satellite. 3D Differential Location -- Indicates the receiver is using DGPS or WAAS differential data on at least four satellites. A "D" will be displayed in or above the indicator bar for each differentially corrected satellite. Lost Satellite Reception -- Indicates that the GPS receiver has lost satellite reception. Simulating GPS -- Indicates the GPS 72 is running in Simulator Mode and the GPS receiver is turned off. It is important to remember when you are using the Simulator, the GPS 72 can not be used for actual navigation. Receiver Status Satellite Signal Strength Satellite Location Time Date Location GPS Information Page 9 Satellite Location Introduction Reference GPS Information Page The location of each available satellite is displayed over two location rings. The outer ring represents the horizon, the inner ring represents 45° above the horizon and the center represents directly overhead. When the unit is using a satellite for navigation, the satellite number will become highlighted on the location rings. The unit can be set to display satellite location with North, or your current track toward the top of the display. Satellite Strength Indicator Bars The Satellite Strength Indicator Bars show the strength of the signal being received, and the status of the signal. The bars will be either shaded with a light grey, or filled with solid black. If the bar is grey, it means that the GPS is receiving a signal from the satellite and is in the process of storing orbital data provided in the GPS signal. When the bar turns solid black, the GPS is using the satellite signal for navigation. A "D" in or above the bar means that differential corrections are being applied to that satellite. Date, Time and Current Location The GPS gets date and time information from the satellites. The satellites are equipped with an atomic clock that is very accurate. Since the GPS clock is derived from timing information sent from the satellite, the GPS clock is also very accurate. Satellite Sky View When the GPS receiver has achieved a 2D or 3D GPS Location, the current location will be displayed in the selected Location Format. If you wish to see the current location in the default (hddd° mm.mmm) format, press the ROCKER up or down to toggle between the active and default format. 10 GPS Information Page Options Menu To activate the Options Menu, from the GPS Information Page press the MENU Key.

The settings are used in fields throughout the unit. `Location Format' -- There are 29 different formats to choose from. See the sidebar for a list of the formats. You should not need to change the format from the default setting unless you are using a chart or paper map for navigation. If so, select the format that matches your chart or map. `Map Datum' -- Datums are used to describe geographic positions for surveying, mapping, and navigation and are not actual maps built in the unit. Although there are over 100 datums available to choose from, you should only need to change the Map Datum if you using a chart or paper map that specifies a different datum in the legend. See Appendix D for a list of Map Datums. Introduction Reference Main Menu Location Tab WARNING: Selecting the wrong map datum can result in substantial position errors. When in doubt, use the default WGS 84 datum for best overall performance. `North Reference' -- Let's you select the reference used in calculating heading informa- tion. You can select `Auto' `True', `Magnetic', `Grid' or `User'. `Auto' provides magnetic north heading references which are automatically determined from your current location. `True' provides headings based upon a true north reference. `Grid' provides headings based on a grid north reference. `User' allows you to specify the magnetic variation at your current location, and provides magnetic north heading references based on the value you entered. WARNING: If `User' is selected, you must periodically update the magnetic variation at your present position. Failure to update this setting may result in substantial differences between the information displayed on your unit and external references, such as a magnetic compass. `Magnetic Variation' -- displays the magnetic variation at your current location. If `User' is selected for the `North Reference', this field is used to enter the magnetic variance. Setup Menu -- `Location' Tab 45 Setup Menu -- `Alarms' Tab Introduction Reference Main Menu Alarms Tab The `Alarms' Tab contains settings for Anchor Drag, Approach and Arrival, Off Course, Shallow Water, and Deep Water. These settings will determine if, and when a warning beep is sounded and/or a message is displayed. `Anchor Drag' -- The Anchor Drag Alarm alerts you when the boat has drifted more than a distance set by the user. The alarm can be turned `On' or `Off'. `Approach and Arrival' -- The Approach and Arrival Alarms alert you when you are approaching a turn or arriving at your destination. `Automatic' will alert you between 15 and 90 seconds before, depending on your speed. `Distance' and `Time' alert you at the specified distance or time. `Off Course' -- The Off Course Alarm will alert you when you are off course more than the distance set. The Off Course alarm can be turned `On' or `Off'. `Shallow Water' -- This alarm requires input from a NMEA device supplying the "DPT" sentence. The Shallow Water alarm will alert you when the water depth is less than the depth set. `Deep Water' -- This alarm requires input form a NMEA device supplying the "DPT" Setup Menu -- `Alarms' Tab sentence. The Deep Water Alarm will alert you when the water is deeper than the depth set. 46 Setup Menu -- `Interface' Tab The Interface Tab contains one field, `Serial Data Format'. This field contains eight settings that allow the GPS 72 to communicate with computer software and other electronic devices. · GARMIN -- Allows the GPS 72 to communicate with GARMIN software and other GARMIN GPS units. · GARMIN DGPS -- Allows the GPS 72 to communicate with GARMIN Differential Correction devices. The unit can have the beacon receiver scan for an available DGPS beacon or can tune the beacon receiver to the frequency and bit rate of a nearby DGPS beacon. · NMEA -- Causes the unit to transmit NMEA 0183, version 2.3 data. It also allows the GPS 72 to accept NMEA data from another NMEA device, like a echo sounder. The baud (speed of communication in bits per second) is displayed in the Baud field. · Text Out -- Allows the GPS 72 to output simple text data that includes, date, time, position, and velocity information. The Baud can be set to 1200, 2400, 4800, or 9600 bps. · RTCM In -- Allows the GPS 72 to accept DGPS information from a device supplying RTCM data in a SC-104 format. The Baud can be set to 1200, 2400, 4800, or 9600 bps. · RTCM In/NMEA Out -- Functions the same as the `GARMIN DGPS' setting except, the unit will output NMEA 0183, version 2.3 sentences, GPRMC, GPGGA, GPGSA, GPGSV, GPGLL, GPBOD, GPRTE, and GPWPL. · RTCM In/Text Out -- The same as the `RTCM In' setting except, the unit will output simple text data that includes date, time, position, and velocity information. The Baud can be set to 1200, 2400, 4800, or 9600 bps. · None -- Turns off all serial communication. Introduction Reference Main Menu Setup Menu -- Interface Tab When any NMEA output is selected, the NMEA data transmission can be customized to keep the update rate at two seconds. With an NMEA output selected, press MENU and select `Setup NMEA Output' to show the setup window. You can set the precision of the location, control how waypoints are identifed, and enable/disable selected NMEA sentences. To change a setting, highlight the field and press ENTER. Make your selection, press ENTER again to accept the selection. To check/uncheck a box, highlight the box and press ENTER.
