For detailed information about this receiver, refer to the owner’s manual that is included with you GPS receiver (a digital version of your owner’s manual can also be downloaded from the Garmin website:( [h t t p : / / w w w 8 . g a r m i n . c o m / m a n u a l s /](h t t p : / / w w w 8 . g a r m i n . c o m / m a n u a l s /)[ ](h t t p : / / w w w 8 . g a r m i n . c o m / m a n u a l s /)[eTrexLegendHCx_OwnersManual.pdf](eTrexLegendHCx_OwnersManual.pdf)) .\u003Cbr>The ETrex GPS receivers are fairly rugged. However, these receivers are small computers, and they should therefore be treated with care. For example, never store the GPS receiver in direct sunlight orin hot areas (car trunks) . When you are not using your GPS receiver for long periods of time (over 2 months), it is recommended that you remove the batteries. The eTrex GPS is fully water resistant and dust proof, however, it does not float! You should clean the outside of your GPS receiver by simply running cool water over it, or by wiping it off with a moist rag.\u003Cbr>In addition, it should be noted that the GPS has an internal antennae. The antennae is located at the top of the GPS receiver (above “eTrex”) . Do not obstruct the antennae when you are operating your GPS! Most GPS receivers do not work inside, underground, or underwater. In order to get the best reception, your GPS receiver will require an unobstructed view of the sky. However with new high sensitivity GPS chip, the eTrex can receive consistently strong signals under dense tree canopy.\u003Cbr>Marketing material suggests that this GPS receiver will require new batteries (\\#2 AA) after approximately 22 hours of use. You may want to keep spare batteries handy. | When purchasing your GPS, it comes with a detailed owner’s manual, and a quick start user’s guide. In addition, your GPS receiver also comes with a USB cable. This cable can be attached to your computer. This will enable you to download or upload coordinates, and can facilitate field data collection.\u003Cbr>A digital version of this manual is accessible from the VCCS Geospatial Portal, or via the Virginia Geospatial Extension Program website:\u003Cbr>[http://www.gep.frec.vt.edu/cooltools.html](http://www.gep.frec.vt.edu/cooltools.html)\u003Cbr>Table of Contents\u003Cbr>Some Tricks of the Trade..................................2\u003Cbr>Understanding Your GPS Receiver ..................3\u003Cbr>Getting Started: Using Your GPS Unit.............5\u003Cbr>Application \\#1: Marking and Saving Waypoints ......................................................6\u003Cbr>Application \\#2: Finding (Navigating to) a Waypoint.....................................................7\u003Cbr>Application \\#3: Finding (Navigating to) a Waypoint defined by someone else ...............8\u003Cbr>Application \\#4: Area Measurements Option-1: The Track Log Method .................9\u003Cbr>Option-2: The Route Method (in office)......11\u003Cbr>Application \\#5: The Trip Computer Page.......12\u003Cbr>The Map Page and Acknowledgements..........15\u003Cbr>|\n\nThe Virginia Geospatial Extension Program  \nSome Tricks of the Trade and things to remember…  \n♦ You know enough to be dangerous!
