FCC Information

This device complies with Part 15 of FCC Rules and Regulations. 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 radiates radio-frequency energy; if not installed and
used in accordance with these instructions, the unit may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in any 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 correct the interference by one or more of the following measures:

1)  Reorient the antenna.
2)  Increase the separation between the affected equipment and the unit.
3)  Connect the affected equipment to a power outlet on a different circuit from the one the receiver is connected

to.

4) Consult the dealer and/or experienced radio/TV technician for help.

FCC ID: NCYM2400S
Canada:

IMPORTANT NOTE:

Intentional or unintentional changes or modifications must not be made unless under the

express consent of the party responsible for compliance. Any such modifications could void the user’s authority to
operate the equipment and will void the manufacturer’s warranty. To comply with FCC RF exposure requirements,
the following antenna installation and device operating configurations must be satisfied. The antenna for this unit
must be fixed and mounted on an outdoor permanent structure with a minimum separation distance of two meters
from any persons. Furthermore, it must not be co-located or operated in conjunction with any other antenna or
transmitter.
