Regulatory Compliance

Federal Communications Commission (FCC) Compliance Statement
CAUTION: Changes or modifications not expressly approved by the manufacturer responsible 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 radio/TV technician for help

Industry Canada (IC) Compliance Statement

This device complies with Industry Canada license-exempt RSS standard(s). 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.

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or
lesser) gain approved for the transmitter by Industry Canada. 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 necessary for successful communication.

This radio transmitter, IC: 5683C-CWD7191, has been approved by Industry Canada to operate with the antenna types
listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly
prohibited for use with this device.

Antenna Type: Dipole, Maximum permissible antenna gain: 2.5 dBi, Impedance: 50 Ohms

Industrie Canada (IC) Déclaration de conformité

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2)
l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en
compromettre le fonctionnement.

Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un
type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques
de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que
la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une
communication satisfaisante.

Le présent émetteur radio , IC: 5683C-CWD7191, a été approuvé par Industrie Canada pour fonctionner avec les types
d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne.
Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement
interdits pour l'exploitation de l'émetteur.

Type d'antenne: Dipole, Gain admissible maximal: 2.5 dBi, Impédance: 50 Ohms

To satisfy RF exposure requirements, this device and its antenna must operate with a separation distance of at least 20
centimeters from all persons and must not be collocated or operating in conjunction with any other antenna or
transmitter.

Crestron CWD7191 Two-Way RF Transceiver Module

Two-Way RF Transceiver Module:
CWD7191

Functions and Features

The CWD7191 (hereafter referred to as “module”), with a dipole antenna or an integrated SMD
antenna, is a two-way radio frequency (RF) module that utilizes the 2.4 GHz frequency band to
communicate with other devices.

The module operates according to the IEEE 802.15.4 specification and can be configured to minimize
the possibility of interference with other devices.

The module receives RF signals from one or more Crestron devices and can transmit these signals over
the air for further processing (depending on the application).

Functional Summary

 2.4 GHz frequency band, IEEE 802.15.4 specification
 Range from 3 feet to 550 ft.
 Operates on one of sixteen available channels to establish optimal signal

quality
