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 (PN #11734) -9.9 dBi gain
Nelson Bowtie antenna +3.7dBi gain
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.”
Son fonctionnement est soumis aux deux conditions suivantes: (1) cet appareil ne peut pas causer
d'interférences, et (2) cet appareil doit accepter toute interférence, y compris les interférences qui
peuvent causer un mauvais fonctionnement de l'appareil. Pour réduire le risque d'interférence aux autres
utilisateurs, le type d'antenne et son gain doivent être choisis afin que la puissance isotrope rayonnée
équivalente (PIRE) ne dépasse pas celle admise pour une communication réussie. Ce dispositif a été
conçu pour fonctionner avec les antennes énumérées ci-dessous, et ayant un gain maximal de 10,2 dBd.
Antennes pas inclus dans cette liste ou ayant un gain supérieur à 10,2 dBd est strictement interdite pour
une utilisation avec cet appareil. L'impédance d'antenne requise est de 50 ohms.
La liste d'antenne approuvé:
- Nelson VRS PCB antenne dipôle (PN # 11734) -9,9 dBi de gain
- Bowtie Nelson antenne 3,7 dBi de gain
- L-Com Modèle # PL-906V Omni 6dBi gain de
- Modèle # Comtelco Y3387 Yagi 10.2dBd gain.
"Pour se conformer à la FCC et Industrie Canada limites d'exposition aux rayonnements RF pour la
population générale, l'antenne (s) utilisée pour ce transmetteur doit être installé de telle sorte qu'une
distance minimale de 20cm est maintenue entre le radiateur (antenne) et toutes les personnes à tout
moment et ne doit pas être co-localisés ou fonctionner en conjonction avec une autre antenne ou un
autre émetteur. "
OEM Responsibilities to comply with FCC and Industry Canada Regulations
The VRS(TWIG) Module has been certified for integration into products only by OEM integrators under
the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 20cm is maintained
between the radiator (antenna) and all persons at all times.
2. The transmitter module must not be co-located or operating in conjunction with any other antenna or
transmitter.
As long as the two conditions above are met, further transmitter testing will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance requirements
required with this module installed (for example, digital device emissions, PC peripheral requirements,
etc.).
IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or colocation with another transmitter), then the FCC and Industry Canada authorizations are no longer
considered valid and the FCC ID and IC Certification Number cannot be used on the final product. In
these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including
the transmitter) and obtaining a separate FCC and Industry Canada authorization.
End Product Labeling
The VRS(TWIG) Module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC
Certification Number are 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.
In that case, the final end product must be labeled in a visible area with the following:
“Contains FCC ID: ZH6‐VRCOMM‐HP”
“Contains IC: 9686A‐VRCOMM‐HP”
The OEM of the VRS(TWIG) Module must only use the approved antenna(s) listed above, which have
been certified with this module.
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module or change RF related parameters in the user manual of the end product.
The user manual for the end product must include the following information in a prominent location:
“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.”
