FCC Statement
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

Industry Canada statement
This device complies with ISED’s licence-exempt RSSs. Operation is subject to the following
two conditions:
1. This device may not cause interference, and
2. this device must accept any interference received, including interference that may cause
undesired operation.
Radio frequency radiation exposure Information for USA and Canada
This equipment complies with FCC and IC radiation exposure limits set forth for an
uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20 cm (8 in)
between the radiator and your body.
