Crestron CWD6609 Two-Way RF Transceiver Module
Two-Way RF Transceiver Module:
CWD6609
Introduction Functions and Features
The CWD6609 (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 or over a cable run for further processing (depending on the
application).
Functional Summary

The transceiver uses a 1.67 milliwatt signal that can travel up to approximately 50
feet indoors. The range is dependent on the construction of the building,
obstructions, and RF interference from other devices. The location of the module and
the orientation of its antenna are also important factors in determining RF
performance.

1. The location and the orientation of the module are important factors in the RF performance. 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. A circuit-board mounted antenna is located at the top of the board
while a 10-pin connector for the application-specific installation is located at the
bottom of the board.

Industry Compliance
Labeling Requirements
If the FCC ID on the CWD6609 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:
EROCWD6609” or “Contains FCC ID: EROCWD6609.” Any similar wording that
expresses the same meaning may be used.
Compliance Statement (Part 15.19 )
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.
Warning (Part 15.21 )
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
RF Exposure (OET Bulletin 65 )
To comply with FCC RF exposure requirements for mobile transmitting devices, this
transmitter should only be used or installed at locations where there is at least 20cm
separation distance between the antenna and all persons.
Industry Canada Statement
The term "IC" before the certification/registration number only signifies that the
Industry Canada technical specifications were met.
IC: 5683C-CWD6609
Section 7.1.5 of RSS-GEN
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.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body. This transmitter must
not be co-located or operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators under the following
conditions:
1. The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
2. The transmitter module may not be co-located with any other transmitter or
antenna.
As long as the two conditions above are met, further transmitter test 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
example certain laptop configurations or co-location with another transmitter), then
the FCC authorization is no longer considered valid and the FCC ID cannot be used
on the final product. In these circumstances, the OEM integrator will be responsible
for reevaluating the end product (including the transmitter) and obtaining a separate
FCC authorization.
