This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
1.this device may not cause harmful interference, and
2.this device must accept any interference received, including interference that may
cause undesired operation.
Modifying this receiver may void your authority to use the equipment. This equipment
has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Refer to Troubleshooting in Chapter 5 for a detailed description of recommended customer
actions.
If none of the remedies on the previous page stops the radio interference, you should
contact a licensed radio/television technician, your satellite dealer, or call the Customer
Service Center at 1-800-333-3474, for assistance.
The attenuator provided with the satellite receiver will limit the signal present at your
television set to below the FCC signal strength limit of 75.6dBuV. If you choose not to
install the provided attenuator, you must ensure that the signal strength present at the
TV set does not exceed 75.6dBuV.
In order to receive local broadcast channels, you may wish to install an off-air antenna
into your TV distribution equipment. When installing the off-air antenna, you must be
careful to meet certain FCC regulations.
There are many devices that allow you to connect your antenna to your in-home
distribution system such as splitters, and amplifiers. The FCC requires that the isolation
between the antenna port and the network port of your system meet the following:
• 80dB from 54 MHz to 216 MHz, at least
• 60dB from 216 MHz to 550 MHz and at least
• 55dB from 550 MHz to 806 MHz
Measuring the isolation of a device requires specialized equipment. In most cases, it is
easier to purchase a splitter or amplifier with the correctly specified isolation from your
local satellite television retailer. The above requirements are extracted from
47CFR15.115. For the complete text please visit WWW.FCC.GOV.
