Federal Communication Commission Interference 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 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.

FCC Caution: Any changes or modifications not expressly approved by the party responsible for

compliance could void the user's authority to operate this equipment.

INDUSTRY CANADA STATEMENTS

Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this

device must accept any interference, including interference that may cause undesired operation of the

device. To reduce potential radio interference to other users, the antenna type and its gain should be so

chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for

successful communication. This device has been designed to operate with the antennas listed below, and

having a maximum gain of 10.2 dBd. Antennas not included in this list or having a gain greater than 10.2

dBd are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.

Approved antenna list:

- Nelson VRS PCB dipole antenna

- L-Com Model #HGV-906V Omni 6dBi gain

- Comtelco Model #Y3387 Yagi 10.2dBd gain.

“To comply with FCC and Industry Canada RF radiation exposure limits for general population, the

antenna(s) used for this transmitter must be installed such that a minimum separation distance of 20cm is

maintained between the radiator (antenna) and all persons at all times and must not be co-located or

operating in conjunction with any other antenna or transmitter.”

“Contains Transmitter Module FCC ID: TFB-SIFLEX2HP IC: 5969A-SIFLEX2HP” 
