To adjust the backlight level:
Hold the unit in front of you facing the sky. While the GPS receiver is searching for the satellite signals, a Locating Satellites message is replaced by an Acquiring Satellites message until enough signals are acquired to fix its location.
The outer circle represents the horizon. The inner circle is a location 45 degrees from the horizon.
Initializing the GPS Receiver
The first time you turn on your eTrex, the GPS receiver must collect satellite data and establish its current location. To receive satellite signals, you must be outdoors and have a clear view of the sky.
The number of each overhead satellite is shown. The strength of each satellite signal is shown.
If the unit cannot establish a satellite fix, a list of solutions appears. Highlight the appropriate solution, and press ENTER.

Power to the unit is provided by batteries or from an auxiliary source. Power status is shown on the Main Menu and the Status Bar. The Battery Power icon shows the remaining power as the battery is depleted. The external power icon is shown when the unit is powered externally. Satellite signal status is shown when searching for or acquiring satellites , a 2D fix is attained and a 3D fix is attained. The Electronic Compass (Vista HCx and Summit HC only) appears when activated.
Many of the eTrex features require detailed mapping data to be fully operational, so you need to transfer maps before using the unit. The eTrex Vista HCx and Legend HCx are equipped with a slot for a microSD card (user provided) that can be loaded with detailed maps from optional MapSource disks. With selected MapSource mapping data, you can view listings of nearby restaurants, lodging, shopping centers, attractions and entertainment, and addresses. The amount of data transferable is 24 MB for the eTrex Summit HC and Venture HC, for the eTrex Vista HCx and Legend HCx it is determined by the size of the microSD card. Use the USB Interface Cable, provided with the unit, to transfer MapSource data from a computer to the microSD card when installed in the eTrex. Purchase additional microSD cards at your local electronics supplier, or see the Garmin Web site: www.garmin.com for compatible MapSource products and pre-loaded microSD cards.

Using the Course or Bearing Pointer
The bearing pointer and course pointer are independent of each other. The bearing pointer indicates the direction to your destination, and the course pointer indicates your relationship to a course line leading to the destination. If the bearing pointer arrow is pointing straight up, for example, you are going directly to your destination. If it points any direction other than up, turn toward that direction until the arrow is pointing up and then continue in that direction. The bearing pointer points to the destination.
If you are using the course pointer option, and you drift away from the line of travel from your original location to your destination, the course deviation indicator (an arrow with horizontal dotted line) provides graphic indication of drift (right or left) according to the scale shown on the compass ring. Move to the right or left to get back on course.

0.25 mi

The course pointer indicates your course of travel from your original location and the distance off course.

The bearing pointer always indicates the direction to your destination from your current location. eTrex HC series Owners Manual31
