Page 11: Reference
Each time the unit receives satellite signals, the Almanac is updated. This is how the GPSMAP 176 knows which satellites to search for. If you do not use the unit for several months, or move the unit several hundred miles between uses, the Almanac can become “cold,” which means the orbital data is no longer valid.
Page 12: Initialization Options
Initialization Options Reference If the GPSMAP 176 is unable to determine its location, an options menu will be displayed. Depending on the situation, select the appropriate option to help the unit acquire satellites. Start Simulator— This option will turn the GPS receiver Off. Select this option if you are indoors Initializing the GPS Receiver and can not receive satellite signals, or if you wish to practice using the unit in simulator mode.
