FCC warning
Compliance Information:
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, 2. This
device must accept any interference received, including interference that may cause
undesired operation. Any changes or modifications to this device not expressly
approved by AViTA Corporation. For compliance could void the user's authority to
operate the equipment.
Note:
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 technician for help.
If the module's FCC ID is not visible when installed in the host, or if the host is
marketed so that end users do not have straightforward commonly used methods for
access to remove the module so that the FCC ID of the module is visible; then an
additional permanent label referring to the enclosed module: “Contains Transmitter
Module FCC ID: UV3BMW-18XX” or “Contains FCC ID: UV3BMW-18XX” must
be used.
