FCC Compliance
Compliance Information Statement
EchoStar Technologies Corporation, 94 Inverness Terrace East, Englewood CO., (303) 706-4000, declares that: 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.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.
Signal Strength Present at the Television
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.
Connecting to an Off-Air Antenna
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.
