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.

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. 

In order to properly install this satellite receiver, you will need to have access to specialized equipment that can measure the picture carrier 

voltage present on the coax cable. If you do not have access to this equipment, it is recommended that you contact a professional installer. 
The FCC requires that amplitude of the signal presented to the television set does not exceed 75.6dBuV. 
If the signal measured at the television exceeds this limit, you are required to employ an attenuator, similar to the one provided with your 

receiver, to decrease the amplitude of the signal until it no longer exceeds 75.6dBuV.

In order to receive local broadcast channels, you may wish to install an over-the-air antenna into your distribution system. When installing 

an 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
