If you see a black screen with the message: “Searching for satellite signal. To access related utilities, press .” press the key. Otherwise, press keys in the following order to navigate to the INSTALLATION screen: · to display the MAIN MENU · or to move the highlight over the Setup Menu button · to display theSETUP MENU · or to move the highlight over the Installation button · to display the INSTALLATION screen You should see a meter displaying your signal strength. The INSTALLATION Screen The INSTALLATION screen shows the quality of the signal that you are receiving. Because you have not adjusted the direction of your satellite dish antenna, you probably have a signal strength of 0. To let you know that it is “looking,” you should hear a short beep every few seconds. Even though a signal strength of 50 will give you the same high- quality picture and sound as a reading of 90, you should maximize your signal as much as possible, because rain or snow can cause the signal strength to drop significantly. This signal reduction is known as “rain fade.” As soon as the signal can penetrate the rain cloud or snow, your picture will return automatically. The INSTALLATION screen PAGE 4-17 DIRECTV SYSTEM FROM HUGHES NETWORK SYSTEMS - OWNER’S MANUAL Pointing the Satellite Dish Antenna Using the “Box” Method Pattern of scanning the sky The easiest way to find the satellite signal is by scanning the sky in the general direction that the satellite is located. While you could possibly achieve this by trial and error, you should be able to find the signal in just a few minutes using the “box” method. What you are effectively doing is scanning the sky in a pattern similar to the way a farmer plows a field. It will be easiest to fine-tune your satellite dish antenna with someone else’s assistance, calling out the signal strength while you make the adjustments. Optionally, you can turn up the volume of your TV so that you can hear the beeps while you make adjustments. When there is no signal, beeps will occur every few seconds so that you know it is searching. As the signal strength increases, the beeps will become much more rapid. Before you begin make these quick checks: • Verify that there are no obstructions such as trees, buildings, etc., blocking the signal. • Verify that you are using the proper cable type (RG-6) between the satellite dish antenna and the digital satellite receiver. Also, be sure that the connections are tight and the center wire in the cable extends about 1/8th-inch beyond the end of the connector. • Verify that the azimuth and elevation values that you determined earlier are correct for your area. • To loosen and tighten the satellite dish antenna’s bolts, you will need a 7/16-inch wrench (not included). • A compass will also be needed to establish the initial direction to point your satellite dish antenna. The “box” method begins by subtracting 10 degrees from the azimuth and subtracting 4 degrees from the elevation values that you determined earlier. We’ll begin by adjusting the elevation. First, loosen the nuts securing the two (one on each side) elevation bolts just enough so that you can easily tilt the reflector up and down. Next, line up the elevation indicator with the tick mark corresponding to the elevation calculated earlier (result minus 4 degrees). This indicator is the leading edge of the metal just to the left of the bolt. It is recessed inside the slot. Do not use the bolt or nut as a point of reference. Finish adjusting the elevation by lightly tightening the bolts when the indicator is aligned with the correct tick PAGE 4-18 INSTALLING AND POINTING YOUR SATELLITE DISH ANTENNA mark. Make sure that the satellite dish antenna doesn’t slip out of position while you are tightening the bolts. Next, we’ll adjust the azimuth. For this part of the procedure, a compass (such as the one included in the Do-It-Yourself Installation Kit) will make it possible to point in the proper direction. This is done by first loosening the azimuth bolts just enough in order to turn the satellite dish antenna smoothly with a little pressure. Stand behind or beneath the satellite dish antenna reflector and, while grasping the outer edges of the reflector, rotate the satellite dish antenna until it is pointing toward the azimuth value determined earlier (result minus 10 degrees). Be sure that as you do this you do not lean on the reflector, as that would affect the alignment. Don’t tighten the bolts just yet! 1) Slowly turn the satellite dish antenna 20 degrees towards and past the actual determined azimuth. It should take about 20 seconds to make the sweep of the sky. 2) If no signal was found in this pass, increase the elevation by 1 degree and slowly turn the satellite dish antenna back the other direction. If you do find a signal, go to step 5. 3) If you have done this for 9 passes (now 4 degrees above the determined elevation), start back at the beginning point and try again. If you cannot achieve any sign...
