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) Compliance Statement
Operation is subject ot 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 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.

Range from 3 feet to 550 ft.
Operates on one of sixteen available channels to establish optimal
signal quality
Two-Way RF Transceiver Module:
CWD6660
Functions and Features
The CWD6660 (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).

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. A SMA
reverse polarity female antenna port is located at edge of the circuit board for attaching a dipole
antenna while a 16-pin header is for the application-specific installation.

Labeling
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: EROCWD6660” or “Contains FCC ID: EROCWD6660.” 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.”
