Getting Started

The Getting Started Section introduces you to the basic operation of the eTrex Summit. The Reference Section shows you how to use all of eTrex Summits remaining features.

The First Step

Here We Go
The eTrex Summits GPS operates using information gathered from satellites. To Initialize the eTrex Summits GPS receiver the rst time, take your eTrex Summit outside and nd a large, open area that has a clear view of the sky. Press and hold the POWER Button to turn the unit on. Youll see the Welcome Page for a few seconds while the eTrex Summit performs a self-test, followed by the SkyView Page.
NOTE: When you use the eTrex Summit for the rst time, it will take up to ve minutes to nd your location. After the rst use, eTrex Summit only needs about 15 to 45 seconds to nd your location.

The SkyView Page

The eTrex Summit needs to receive at least three strong satellite signals to nd your location. The SkyView Page shows you graphically eTrex Summit tracking satellites, and the strength of the satellite signals. The status is also displayed at the top of the page.

Reference Tracks

What is a Track Log?
The eTrex Summit draws an electronic breadcrumb trail on the Map Page as you travel along. This breadcrumb trail is the Track Log. The Track Log contains information about each point that it plots along the way, including time, position and elevation. After a Track Log is saved in the units memory, the eTrex Summit can use the Track Logs information to navigate, review the saved Track Log on the map or to review the Track Logs elevation prole. TracBack allows you to return along a traveled path without marking any waypoints. When you are ready to return to where you started, eTrex Summit will take you back by following the Track Log that you left behind. You can save a total of ten Track Logs in the eTrex Summit. The Track Log starts recording as soon as the eTrex Summit gets a location x. If you want to use the Tracback feature it is recommend that you clear the Track Log before you start traveling. The percentage of memory used by the current Track Log is displayed at the top of the Tracks page. After the Track Log is CLEARED, it will show zero percent. When the display shows 99%, the most recent track points will start overwriting the beginning track points, in order to avoid losing any track points, you should save the Track Log before it reaches 99% of memory usage. Saved tracks can be used for navigation later. After a Track Log is saved, the saved track will have a beginning (BEGIN) point and an ending (END) point.
Clearing the Current Track Log:
1. With the MENU page displayed, highlight TRACKS and press ENTER. The TRACK LOG Page will appear. 2. Highlight the CLEAR Button and press ENTER. 3. You will be asked DO YOU REALLY WANT TO CLEAR THE TRACK LOG?. Highlight YES and press ENTER to clear the current Track Log.

The eTrex Summit can be set to disable the Electronic Compass above a user selected speed. This helps to conserve battery power.

North Reference

Reference refers to the orientation of a maps grid. Map makers try to align the vertical lines on a map with True North. True North is the direction from any location on the earths surface to the North Pole. Maps are typically referenced to true north. Because a compass points to magnetic north, not true north, maps indicate the difference between true and magnetic north with something called variation or declination.
Set a time delay before switching to the electronic compass when moving at a speed slower than the user-selectable speed.
Reference North Reference
The amount of variation/declination changes as you move around the earth. Magnetic North is the direction in which a compass needle points. Due to errors introduced when map makers atten the earths sphere onto paper, not all of the grid lines drawn on the map point exactly to the north pole, so the north indicated by the grid lines is called Grid North. But, the difference is usually small enough that Grid north can be considered the same as True North for travelling on land. If necessary, you can correct for the difference between Grid North and True North manually. The eTrex Summit will reect the North Reference setting when using the GPS or Electronic Compass for a bearing.
The eTrex Summit automatically adjusts the variation/declination. While it shold rarely be needed the user can manually adjust the variation/declination.
The Electronic Compass will reect the North Reference setting. If you have selected TRUE NORTH the Electronic Compass will point TRUE NORTH not Magnetic North.
To change the North Reference:
1. With the MENU page displayed using the UP or DOWN Button highlight SETUP and press ENTER. 2. Using the UP or DOWN Button to highlight HEADING and press ENTER. The HEADING Page appears. 3. Using the UP or DOWN Button select the NORTH REF eld and press ENTER. 4. Using the UP or DOWN Button select the desired reference. Press ENTER. Press PAGE to return to the page of your choice.

The unit should be securely packaged with the tracking number clearly marked on the outside of the package, and sent freight prepaid and insured to a GARMIN warranty service station. A copy of the original sales receipt is required as the proof of purchase for warranty repairs. GARMIN retains the exclusive right to repair or replace the unit or software or offer a full refund of the purchase price at its sole discretion. SUCH REMEDY SHALL BE YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY BREACH OF WARRANTY.
