To
use the receiver, push the Power (PWR) button once, then the Enter
button. Initially a STATUS screen, showing satellite signal
capture and battery condition information (more below).
The Quit button ends the current display and returns you to the previous display. The Navigation (NAV) button scrolls through a variety of display screens; ordinarily you need the POSITION screen (see below). The Illumination button (the light bulb) provides screen backlighting. It also wastes battery power; do not use it. The Mark button records positional information for the locations where you push it, as "waypoints". These remain stored in the receiver until 1) you delete them, or 2) the batteries go dead. The GOTO button brings up screens enabling you to select a previously stored waypoint, then can display information about the direction ("bearing") to that target waypoint, the distance to it, your current direction of travel ("heading"), and your speed. You must move the receiver at least 3 mph for this function to work properly. It is also possible to program the receiver with destination coordinates; see below. The Menu button brings up many changeable options and settings. The circular ARROWS button enables you to select various options from a screen display. When you initially start the unit, a STATUS screen is in view while the receiver attempts to capture a necessary number of signals from several satellites. The outer circle represents the horizon, the inner circle is 45 degrees above the horizon, and the center of the circles is directly overhead; north here is at the top. A black square is a satellite that the receiver has locked onto, and a gray square indicates a detected satellite that has a weak signal. The histograms below the circles indicate the relative signal strengths (solid for ready, open for ephemeris still being collected). Both displays give the satellite ID number. After the receiver has at least three locked satellites, the display shifts to POSITION. When this first comes on it will have a segmented bar across the bottom; you should push the left or right arrow key to bring in the display of position in both UTM and latitude/longitude (diagram at left). Here the UTM coordinates appear at the top, followed by elevation, universal coordinated time, date, estimated position error (EPE), and datum; latitude and longitude (here in degrees, minutes, and seconds) appear below the black line. If you have this display at your site position, push Mark to save the information as a waypoint. When you do, another screen comes up with "LMK00x" highlighted. Push Enter. Then use the up or down Arrow keys to select letters, and the right arrow key to move to the next character position. You can label (up to six characters) your waypoint this way, and then hit Enter when done. Then hit the down Arrow until "Save Landmark" has highlighting, then hit enter. You have now saved your waypoint and its label. To program the coordinates of a destination, begin by marking and labeling your current location. Then use Menu-Landmarks-User to highlight the landmark you just made. Press the Menu button, highlight "Edit Landmark", then use the Down Arrow to highlight the landmark coordinates. Hit the Enter button, then a second time to keep in the northern hemisphere. Use the right or left arrows to highlight the characters you wish to change, and the up or down arrows to change those characters. Enter at the end of each coordinate string, then arrow down to "Save Edits" and hit enter. Now you can hit the "GOTO" button and the receiver will begin guiding you in. |
