FCC Statement

This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device

does not cause harmful interference.

Warning: Changes or modifications not expressly approved by the party responsible for compliance could

void the user's authority to operate the equipment.

The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20cm

from all persons and must not be co-located or operate in conjunction with any other antenna or transmitter.

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 radio/TV technician for help.

If the FCC identification number is not visible when the module is installed inside another device,

then the outside of the device into which the module is installed must also display a label

referring to the enclosed module. This exterior label can use wording such as the following:

“Contains Transmitter Module FCC ID: PJ7-1721” or “Contains FCC ID: PJ7-1721”
