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 helpIndustry Canada (IC) Compliance Statement Operation is subject to the following two conditions: 1. This device may not cause interference, and2. This device must accept any interference, including interference that may cause undesired operation of thedevice.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 collocated or operating in conjunction with any other antenna or transmitter.

Crestron CWD7545 Two-Way RF Transceiver Module Two-Way RF Transceiver Module: CWD7545 Functions and Features The CWD7545 (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). Functional Summary • 2.4 GHz frequency band, IEEE 802.15.4 specification • Range from 3 feet to 100 ft. • Operates on one of sixteen available channels to establish optimal signal quality Operations Guide - DOC.

Two-Way RF Transceiver Module Crestron CWD7545 Specifications The table below is a summary of specifications for the CWD7545. Specifications of the CWD7545 SPECIFICATION DETAILS Power Requirements 1.55 Watts (5VDC @ 0.310A) Operating Frequency 2400 MHz to 2483.5 MHz (802.15.4 compliant) Operating Ranges¹ Minimum Distance 3 ft Maximum Distance Indoors 100 ft (without repeater device) Available Channels 16 (numbered 11 through 26 per 802.15.4) Antenna Mini Chip Antenna (2450AT42E0100) Dimensions Width: 1.88 in (0.477 cm) Height: 0.82 in (0.208 cm) Depth: 0.100 in (0.254 cm) 1. 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.

Two-Way RF Transceiver Module Crestron CWD7545 Setup Hardware Hookup Refer to the /I-O Pinout Signals table which shows the connections made to the module. NOTE: To prevent unit-to-unit RF interference, multiple modules operating at the same frequencies should not be installed within three to five feet of each other. 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: EROCWD7545” or “Contains FCC ID: EROCWD7545.” 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 user’s manual of the end product. The user’s 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.” 4 • Two-Way RF Transceiver Module: CWD7545 Operations Guide - DOC.
