Troubleshooting; Signal Loss / Rain Fade - SELFSAT H22dCSS+ Serie Manuel Utilisateur

Troubleshooting

If the signal is not found, be sure the STB user manual and the antenna user manual
have been followed closely, check the following:
• Make sure all cable connections are correct and each connection is seated / tightened properly.
• Inspect the inside of each cable connector for dirt or possible connector to case/shield short.
• Verify the Azimuth, Elevation and Skew angles for your location by ZIP code.
• Make sure the Tilt and Elevation pointers are aligned correctly to the scales. Do not use washer or bolt as
reference.
• Make sure the Tilt adjustment is not changed from the recommended setting for the antenna location.
• Remove exiting TV-specific components, such as TV splitter, etc; reduce the installation to the basic
connections called out in this guide. Such components may not work with the satellite signal and they
may be in the wall where you can't see them. When in doubt, run RG 6 cable directly to your STB.
• Make sure there are no obstructions (trees, buildings, windows, corner or overhang of your roof, your
body or hands) .
• RG 6 cable with solid copper center conductor is highly recommended because it has much lower DC
voltage drop compared to RG 6 cable with a copper-coated, steel center conductor.
• Standard RG 59 cable causes too much DC drop and signal drop; it can not be used to pass the satellite
signal. RG 6 coaxial cable must be used.
• Some after-market, off-the-shelf add-on components may not be as advertised. They might not work or
could cause additional DC drops and signal amplitude attenuation. Remove such components, go back
to the basic connections called out in this manual and re-verify.
• Make sure the satellite cable is connected to the "Sat In" jack, not the "Antenna In" jack. The "Antenna In"
jack at the back of the receiver is for off-air antenna input or cable TV input.
• If all are done correctly but the signal is still not found, change the Elevation adjustment of the antenna
slightly (±2°C, the ±4°C from the called-for setting) and repeat the procedure.
• Make sure the Access Card from your STB is fully inserted into the Access Card slot and oriented correctly.

Signal loss / Rain fade

The satellite signal may be lost temporarily due to unusually
•
heavy rainfall. An optimally aligned antenna, along with the
shortest possible cable run, minimizes the chances of "rain
fade."
Make sure the antenna is mounted securely to prevent it from
•
being blown out of alignment in a heavy wind.
Heavy snow accumulation on the antenna may reduce the
•
satellite signal strength; snow should be swept away as soon as
possible.
Tree foliage growth into antenna's line-of-sight to the satellite
•
may result in gradual loss of picture.
Installation using long cable
•
For installations where the RG 6 cable runs from the STB to the LNB far exceeds 30m(45m or
more), as encountered in a commercial or multi-dwelling building, you need more supportive
power for stabilization.
•
You will also need an additional RF signal amplifier to compensate the signal amplitude loss.
Otherwise, your antenna and STB may not work properly and be subject to frequent outages in
adverse weather. Contact the professional concerning such installations.
