Regulatory Compliance
Federal Communications Commission (FCC) Compliance Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following 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.
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 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 if 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) Notice of Compliance
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 device complies with Industry Canada licence-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.
Industrie Canada (IC) avis de conformité
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 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.
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 colocated or operating in conjunction with any other antenna or transmitter.

signal quality
Two-Way RF Transceiver Module:
CWD7083
Functions and Features
The CWD7083 (hereafter referred to as “module”) 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).

Specifications of the CWD7083
SPECIFICATION DETAILS
Power Requirements 0.825 Watts (5VDC @ 0.167A)
Operating Frequency 2400 MHz to 2483.5 MHz (802.15.4 compliant)
Operating Ranges*
Minimum Distance
Maximum Distance Indoors
(without repeater device)
3 ft
100 ft
Available Channels 16 (numbered 11 through 26 per 802.15.4)
Antenna Chip
Dimensions Width: 1.88 in (4.77 cm)
Height: 0.82 in (2.08 cm)
Depth: 0.10 in (0.25 cm)
* The location and orientation of the module are important factors in the RF performance. With the unit located outside
of any metal enclosures, the antenna is adjusted to achieve the best range. The range is dependent on its placement and
the building in which it is used. The construction of the building, obstructions, and RF interference from other devices
are factors determining the effective range of the unit. To prevent unit-to-unit RF interference, multiple modules
operating at the same frequencies should not be installed within 3-5 feet of each other.
Physical Description
The module, shown below, consists of various components attached to a printed circuit board.

Setup
For hardware hookup, refer to the “Power/I-O Pinout Signals” table on the previous page, which shows
the connection made to the module.
NOTE: To prevent unit-to-unit RF interference, multiple modules operating at the same frequencies
should not be installed within 3 to 5 feet of each other.
Labeling Requirements
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: EROCWD7083” or “Contains FCC ID: EROCWD7083.” Any similar wording that
expresses the same meaning may be used.
Documentation
The OEM integrator has to be aware not to provide information to the end user regarding how to install
or remove this RF module in the users manual of the end product.
The users manual for OEM integrators must include the following information in a prominent location.
“IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-located
or operating in conjunction with any other antenna or transmitter.”
