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.

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 Two-Way RF Transceiver Module Crestron CWD6782 2 • Two-Way RF Transceiver Module: CWD6782 Operations Guide - DOC. 7069A Specifications The table below is a summary of specifications for the CWD6782. Specifications of the CWD6782 SPECIFICATION DETAILS Power Requirements 1.3 Watts (5VDC @ 0.26A) Operating Frequency 2400 MHz to 2483.5 MHz (802.15.4 compliant) Operating Ranges* Minimum Distance Maximum Distance Indoors (without repeater device) 3 ft 550 ft Available Channels 16 (numbered 11 through 26 per 802.15.4) Antenna Gain: 2.0±0.5 dBi max. Type: Sleeve Dipole Antenna Frequency: 2.4GHz to 2.5 GHz Connector Type: SMA Plug Reverse Polarity Connector with ¼-36 UNS2B Screw Antenna Max. Gain: 1.8 dBi Average Gain: -1.9 dBi Type: SMD Frequency: 2.4GHz to 2.5 GHz Dimensions Width: 1.80 in (4.572 cm) Height: 2.50 in (6.35 cm) Depth: 0.45 in (1.143 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.
