4.3 Turning on the System
Before powering on the system check to see that all of the cables on the rear of the antenna control
unit (ACU) are engaged and secure. To apply power to the system, toggle the power switch to the
ON position. The Status light will begin to blink slowly (approximately once per second). This
indicates the system has power applied and is in idle mode.
To turn off power, return the power switch to the OFF position. The ACU status light will turn off.
4.4 Determining Satellite Elevation
Entering an angle to the satellite allows your system to acquire the signal very quickly. Acquisition
will usually occur in less than two (2) minutes if you enter your elevation correctly. There are two
ways of determining the elevation value to enter on the Elevation Angle Selector of the ACU’s front
panel. For DIRECTV at 101° West, use the map of the United States located on the back cover of
this guide. Locate your position on the map and determine the elevation line closest to your location.
Read the elevation value of the elevation line. This is the number to be entered on the front panel.
Alternatively, for DISH Network or DIRECTV, if you know your ZIP code or your current
latitude and longitude, your receiver has a menu selection that calculates the elevation angle. See your
receiver’s operating instructions for details.
4.5 Entering Satellite Elevation
Enter the elevation angle into the Elevation Angle Selector by pressing the buttons located directly
above and below each digit of the Selector. Pressing the button below increases the digit and pressing
the button above decreases the digit.
Elevation values less than 10 or greater than 65 are not valid. The automatic acquisition feature will
not operate without a valid elevation angle. Even if you are a few degrees off in your entry of the
elevation angle, the antenna will still locate the satellite signal. An accurate angle will allow faster
acquisition. See the section “Automatic Satellite Signal Acquisition and Peaking” for more details.
The advantage of entering the correct elevation angle is that the system will generally locate the
satellite signal on its first azimuth sweep. Altogether, the DBS-30500 will make 8 complete passes
spanning twelve degrees while searching for the satellite’s signal when in the set elevation mode.
