This completes a basic explanation of the page features of the eTrex. Discovering the Fun of GPS Navigation Discovering how to use your eTrex is as easy as taking a quick walk around an open outdoor area. In this brief exercise, you’ll mark your current location (your home...
To change the waypoint name: 1. On the ‘MARK WAYPOINT’ Page, press the UP or DOWN Button to highlight the Waypoint Name ‘001’. 2. Press ENTER. The ‘EDIT WAYPOINT NAME’ Page appears. 3. Press ENTER. Using the UP or DOWN Button, scroll through the letter selections.
When the pointer points straight up as shown, you’re on track! Guidance by Garmin The eTrex guides you to a destination using a GOTO (GOTO means Going TO a destination in a direct line). Now let’ s use the GOTO feature and the Pointer Page to travel back to our starting location.
The destination name, distance to the destination and time to reach your destination are displayed at the top of the screen. The speed you are traveling is shown at the bottom of the screen. Once you are getting close to your destination, the eTrex will give you the message “ARRIV- ING DESTINATION”.
Reference Map Page Options Selecting ‘Orient Map Ahead’ from the Map Page options orients the map to the direction you are moving. When you select ‘Orient Map Northward’ the fi gure icon is replaced by a ‘direction’ triangle. The tip of the triangle tells you the general direction you are moving.
Navigation Page Options In addition to the Navigation Page basics that were covered on page 12, the following Navigation Page options are available: • Reset Max Speed: this resets the Maximum Speed achieved during a trip. • Reset Trip: the trip time, trip distance (odometer) and average speed are reset to zeros.
Reference Navigation Page Options Navigation Page Data Fields You can also change the fi elds at the bottom of the Navigation Page to display different data: Speed—like the speedometer in your car, ‘SPEED’ tells you how fast you are going regardless of whether or not you are on the right track.
NOTE: Elevation or vertical accuracy will always be somewhat less accurate than loca- tion or horizontal accuracy. This is a function of GPS measurement methods which use a mathematical model of the earth to determine elevation. Reference...
Reference Mark Waypoint Page The ‘EDIT LOCATION’ Page displays on-screen instructions on how to edit the waypoint location. The ‘ENTER CORRECT ELEVATION’ Page allows you to change the elevation for the waypoint. To change the location (position coordinates): 1. Press the PAGE Button and switch to the ‘MENU’ Page.
Waypoints Page The Waypoints Page organizes all of your waypoints in alphabetical order for easy selection. It also allows you to select nine of the ‘NEAREST WAYPOINTS’, and if you want, delete all waypoints. To select a waypoint: 1. Press the PAGE Button and switch to the ‘MENU’ Page.
Reference Review Waypoint Page The ‘REVIEW WAYPOINT’ Page allows you to delete a waypoint. You can start a GOTO from the ‘REVIEW WAYPOINT’ Page. Review Waypoint Page The Review Waypoint Page allows you to change the waypoint symbol, name, elevation and location (just like on the Mark Waypoint Page).
Hunt & Fish Page The Hunt and Fish Page provides you with a listing of best times for hunting and fi shing for the chosen location (waypoint) and date. This page also provides the Sun and Moon Page option. To view the Hunt /Fish Page: 1.

If you select the ‘DEMO’ mode, a window appears at the bottom of the screen asking you to verify that you want to turn the GPS off (the unit will stop tracking satellites, not power off). To do so, press ENTER.
The temperature rating for the eTrex may exceed the usable range of some batteries. Alkaline bat teries can rupture at high temperatures. External power can only be applied using the Garmin Auto Power Adapter (P/N 010-10203-00) or PC Interface Cable with Auto Power Adapter (P/N 010- 10268-00-this cable contains a voltage regulator).
Meanwhile, receivers used on the ground, sea and air search the sky for the satellites. The GPS unit needs to acquire good signals from at least three satellites to determine a position on the surface of the earth. A fourth signal is required to get three-dimensional positioning which determines elevation or altitude.
Appendices Appendix C Reception Tips Clouds and weather do not affect the operation of the eTrex! The eTrex has a 12 parallel channel receiver for fast, accurate position fi xes, even under heavy foliage and tree canopy.

DGPS (Differential GPS) corrections are accepted in RTCM SC-104 version 3.0 format through the ‘Data In’ line. The Garmin GBR 21 and GBR 23 are the recom- mended beacon receivers for use with the eTrex. Other beacon receivers with the correct RTCM format may be used, but may not correctly display status or allow tuning control from the GPS unit.
NOTE: The Auto Power Adapter converts 12 VDC to 3 VDC output for the eTrex. This adapter is not interchangeable with car power adapters designed for the Garmin VHF 720 and 725, GPS 170, 175, 190 and 195. Appendices Appendix F...
Does the eTrex work anywhere in the world and in any weather? Yes. How accurate is a Garmin GPS? The eTrex is accurate to within 15 meters without the DoD-imposed Selective Availability (S/A). Using differential techniques, the eTrex can be as accu- rate as 1-5 meters.
