GPSmap 76C Getting Started Initialization & the Satellite Page The GPSmap 76C locates satellites above its position Heading Bug indicates your direction of movement. Options Menu Satellite Page Acquiring Satellite Signals 4 Starting Up the GPS Receiver When you turn on the GPSmap 76C, the GPS receiver begins to search for satellites in order to determine (fix) its location. This process is called "initialization" and can take from 5 to 15 minutes the first time you use your unit. Thereafter, if you haven't moved more than 600 miles from your original location, it takes only seconds to minutes. In order to receive satellite signals, you must be outdoors and have a clear view of the sky. Satellite signals cannot pass through solid materials (except glass) or dense overhead tree cover. To shorten the time required for initialization, select "New Location" from the options menu, then use the Map Page to determine your general location so the GPSmap 76C can search for those satellites above you. To initialize your GPSmap 76C: 1. Press and release the POWER key to turn on the unit. 2. Observe the "Power On" Page followed by the Satellite Page. 3. While the GPS receiver is searching for the satellite signals, a "Locating Satellites" message is replaced by an "Acquiring Satellites" message until enough signals are acquired to fix its location. If the unit cannot get a satellite fix, a list of solutions appears. Highlight the appropriate solution and press ENTER. You can also observe a sky view array of the satellites overhead with your position centered in the array. The outer circle represents the horizon and the inner circle a position 45o from the horizon. The numbers displayed indicate the number assigned to each satellite. A bar graph at the bottom of the page displays the strength of signals from each satellite.
