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 ISED Canada (IC) Compliance Statement This device contains license-exempt transmitter/receiver that comply with Innovation, Science and Economic Development Canada’s license-exempt RSS(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. 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. Déclaration de conformité à ISDE Canada (IC) Cet appareil contient un émetteur / récepteur exempt de licence conforme aux RSS (ou aux RSS) de Innovation, Sciences et Développement économique Canada. Le fonctionnement est soumis aux deux conditions suivantes: 1.Cet appareil ne doit pas causer d'interférences, et2.Cet appareil doit accepter toutes les interférences, y compris celles pouvant entraîner un fonctionnement non souhaité du dispositif. Pour satisfaire aux exigences en matière d'exposition aux radiofréquences, cet appareil et son antenne doivent fonctionner à une distance de séparation d'au moins 20 centimètres de toute personne et ne doivent pas être situés dans un même lieu ni être utilisés avec toute autre antenne ou émetteur.

The transceiver operates according to the IEEE 802.15.4 specification and can be configured to minimize the possibility of interference with other devices. The transceiver 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 Operations Guide - DOC. 7787A Two-Way RF Transceiver Transceiver: CWD7787 • 1 • 2.4 GHz frequency band, IEEE 802.15.4 specification • Range from 3 feet to 500 ft. • Operates on one of sixteen available channels to establish optimal signal quality Two-Way RF Transceiver Crestron CWD7787 Specifications The table below is a summary of specifications for the CWD7787. Specifications of the CWD7787 1. The location and orientation of the Antenna are important factors in the RF performance. 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 transceivers operating at the same frequencies should not be installed within 3-5 feet of each other.
