1Setup,Features,andBasic NavigationSECTION 2Before you begin to explore the eTrex Vista’s operatingfeatures, you will want to follow these “Getting Started”instructions to prepare it for operation by installing bat-teries, adjusting the screen contrast, loading optionalGARMIN MapSource® mapping data, and setting the cor-rect time for your current location.The operating features of the unit are structured tobe accessed and activated by pressing buttons on the unitwhich is explained on the following page.The six Main Pages are your primary access to operat-ing the eTrex Vista. Each page provides either a basicnavigation function or access to features which enhancenavigation or customize the unit’s operation.This “Getting Started” section will introduce you tothe Main Pages and how they are structured. You will alsobe shown how to perform basic navigation techniques tohelp you start using your eTrex Vista immediately.Detailed instructions on using the eTrex Vista’s featuresand their options are contained in the “Reference” section.Features include:Storage for 500 Waypoints with name and graphic symbol.An automatic Track Log with storage capability for 10Tracks with 250 points each.Route building capability, with storage for 20 Routes with50 Waypoints each.A Trip Computer for displaying a variety of navigationdata such as speed, ETA, ETE, heading, odometer, etc.An Elevation Computer for displaying total ascent/descent,average ascent/descent, maximum ascent/descent, 12 hourpressure trend, and maximum/minimum elevation.A Find Feature for locating Waypoints, Cities, InterstateExits, Points of Interest, Street Addresses and Intersections.*24 MB of detailed map data storage, allowing transferfrom GARMIN MapSource CD-ROM’s.Wide Area Augmentation System (WAAS) capability.**Getting Started* Points of Interest, Address,and Intersection data mustbe transferred to the unitusing a GARMIN MapSourceCD-ROM. See pages 4 and 63for more information.** About WAASBecause the Wide Area Aug-mentation System (WAAS) iscurrently under developmentand is not fully supported bygeo-stationary satellites, effec-tive use of the WAAS featuremay be limited by your geo-graphic location in relation tothose satellites now in service.There are two WAAS satellitesin service in geo-stationaryorbit above the Equator, oneover the Atlantic Ocean andone over the Pacifi c Ocean.Currently, WAAS satellite signalreception requires an absoluteclear view of the sky and worksbest when there are no nearbyobstructions such as buildings,mountains, etc. In fact, you maynot be able to receive or easilymaintain a WAAS satellite signaluntil full satellite support for thisprogram is complete.Not enabling WAAS when youcannot receive a signal willspeed unit map drawing andconserve battery power.See page 57 for enabling WAASand satellite receptiontechniques.
