Rino ® 120 Owner’s Manual 7GETTING STARTED > U NDERSTANDING GPSUnderstanding GPSThe Global Positioning System (GPS) consists of 24satellites that circle the earth twice a day in a very preciseorbit and transmit information to Earth. The Rino 120must continuously “see” at least three of these satellitesto calculate your location and track your movement. Ifsome of the satellites in view get blocked or “shaded,” thereceiver simply uses an alternate satellite to maintain thelocation fix.Because the Rino 120 relies on satellite signals to provideyou with navigation guidance, the receiver needs tohave an unobstructed, clear view of the sky for bestperformance. In a nutshell, the GPS receiver’s view of thesky generally determines how fast you get a location fixor if you get a fix at all. GPS signals are relatively weakand do not travel through rocks, buildings, people, ormetal: So, remember to keep a clear view of the sky at alltimes for best performance.Your Rino 120 needs to be given the opportunity to findor AutoLocate itself: This is also called initializing thereceiver or unit.Longer initialization (AutoLocate) is only necessary:• The first time you use your Rino 120 (new from thefactory).• After the receiver has been moved over 500 mileswith the power off from the last time you used it.Once you initialize the unit to a location, it typicallycomputes a fix within a couple minutes.Visit the Garmin Web site at www.garmin.com for moreinformation on GPS.
