GPSMAP 76 Owner’s Manual BASIC OPERATION > INITIALIZING THE GPS RECEIVER Initializing the GPS Receiver The GPSMAP 76 needs to be initialized the ﬁrst time the unit is used, if it has been stored several months, or if it has been moved over 600 miles. The Almanac within unit stores each satellite’s orbital data that is supplied in the satellite signals. The GPSMAP 76 uses the Almanac to know which satellites to search for and automatically updates each time the unit aquires satellites. If you do not use your GPS for several months or move the unit over 600 miles between uses, the Almanac can become “cold” and the orbital information is no longer valid. Your unit may have trouble locking on to satellite signals using a “cold” Almanac. If the unit is unable to receive enough satellite signals to determine its location and update the Almanac, it displays an options menu. GPSMAP 76 Owner’s Manual Initializing the GPS Receiver: 1. With fresh batteries installed, take the unit outside for a clear 360° view of the sky. 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 GPSMAP 76 no longer than ﬁve minutes to acquire enough satellite signals to become operational. When the unit is able to navigate, it displays either 2D GPS Location or 3D GPS Location in the Receiver Status ﬁeld. 7 BASIC OPERATION > INITIALIZING THE GPS RECEIVER Initialization Options If the GPSMAP 76 is unable to determine its location, an options menu is displayed. Select the appropriate option to help the unit acquire satellites. Highlight the option and then press ENTER to select. Start Simulator—is used for practicing with the unit while inside and satellite signals are not available. When you select Simulator, the GPS receiver is turned off saving battery power. Stored w/o Batteries—is used when the date stored in the unit may be incorrect due to storage without batteries. 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—is used when in an area where the satellite signals are being temporarily blocked. New Location—is used when you have moved the unit over 600 miles and are having trouble locking onto satellite signals. When you select New Location, another menu is displayed. This menu contains the options Automatic or Use Map. If you select Automatic, the unit switches to the AutoLocate mode and begin searching for satellites. This process may take longer to acquire satellites. Use Map utilizes the pointer on the Map page to select your approximate location. Then the unit continues to acquire satellites normally. 8 When initializing the receiver or trying to receive satellite signals, orient the GPSMAP 76 so the top of the unit points toward the sky. If the unit is held with the top of the unit pointed toward the horizon, satellite reception may be severly degraded. GPSMAP 76 Owner’s Manual BASIC OPERATION > CREATING A WAYPOINT Creating a Waypoint The term Waypoint may be new to you, but is frequently used when discussing navigation. A Waypoint is a position stored in the unit’s memory used for direct navigation or to build a Route.

The Wide Area Augmentation System (WAAS) is an F.A.A. funded project to improve the overall integrity of the GPS signal. It is a space-based system that broadcasts integrity information and correction data as determined by ground reference stations. WAAS testing completed in September of 2003 conﬁrmed an accuracy of 2 to 3 vertical meters throughout the majority of the continental U.S. and portions of Alaska. For more information, go to http://gps.faa.gov/Programs/WAAS/waas.htm What is Differential GPS (DGPS)? The U.S. and Canadian governments (among others) have set up Differential GPS (DGPS) stations to transmit correction signals. They are operational in coastal areas and on many navigable river systems. The DGPS system is available for use without a fee. Please refer to the U.S. Coast Guard’s Web site http://www.navcen.uscg.gov/ for locations and the status of the differential sites. Using DGPS requires additional equipment. NOTE: If you are using the GPSMAP 76 outside of the U.S., it is recommended that you turn off WAAS for the most accurate location ﬁx.

The name LORAN is an acronym for “LOng RAnge Navigation.” The LORAN system covers the entire United States and the U.S. Coastal Conﬂuence Zone. From the perspective of a mariner, the system is used for ocean and coastal navigation. It can be used as a supplemental system for harbor and harbor approach navigation, and it is used for inland navigation by recreational vehicles. LORAN TD Feature The LORAN TD (Time Delay) feature eases the transition from using LORAN to using GPS. The GPSMAP unit automatically converts GPS coordinates to LORAN TDs for those who have a collection of LORAN ﬁxes for favorite ﬁshing spots and other waypoints recorded as TDs. You can display your position as a TD or enter waypoints as TDs. The accuracy to be expected from this conversion is approximately thirty meters. When the unit is placed in the LORAN TD format mode, it simulates the operation of a LORAN receiver. Position coordinates may be displayed as TDs, and all navigation functions may be used as if the unit was actually receiving LORAN signals. Using the LORAN TD Format When creating new waypoints using LORAN TD coordinates, you must set the correct LORAN chain number and secondary stations in the Setup TD ﬁeld before storing the waypoint. After the waypoint is stored in unit memory, it will always reference the LORAN chain number and secondary stations 68 GPSMAP 76 Owner’s Manual APPENDIX > LORAN TD currently selected in the Setup TD ﬁeld. If you enter a different LORAN chain number, change the secondary stations or offsets in the Setup TD ﬁeld, the active waypoint information will reﬂect those changes. Since the GPSMAP 76 does not rely on the LORAN signal for navigation, it can reference a different GRI chain and/or secondary stations and still navigate to the location stored in memory. The Location Format ﬁeld is accessed in the Main Menu under the Setup option’s Location tab. The ‘LORAN TD Setup’ window contains the ﬁelds to select the Loran GRI-Chain Number, Primary and Secondary Stations, and TD Offsets. If the active GRI Chain, Secondary Stations, or Offsets are changed, all waypoints stored in the units memory will update and reference the the new settings when displayed as a LORAN TD. It is important to note that the saved coordinates of the waypoint are not being modiﬁed, they are only being displayed in reference to the different GRI Chain, Secondary Stations or Offsets. Remember that the GPS is not relying on the LORAN signal for navigation. The GPSMAP 76 converts the GPSMAP 76 Owner’s Manual TD coordinate to a LAT/LON coordinate before storing a waypoint to memory. The unit can navigate to a converted TD coordinate anywhere in the world. To setup Loran TD from the Main Menu: 1. Using the ROCKER, highlight the Location Format ﬁeld on the Location tab and press ENTER. 2. Highlight Loran TD, press ENTER. This displays the LORAN TD Setup window. 3. To change the settings of any of the ﬁve ﬁelds, highlight the ﬁeld, press ENTER, select/enter the desired setting then press ENTER. 4. When done, press the PAGE key to return to the Main Menu. 69 APPENDIX > ASSESSORIES Accessories Automotive Mounting Bracket Requires the Marine Mount Part No. 010-10300-00.
