WA-TX-03-R and WA-RX-03-R

Regulatory compliance of the WA-TX-03-R and the WA-RX-03-R The WA-TX-03-R and the WA-RX-03-R are designed for embedding in other equipment. (Products incorporating the WA-TX-03-R and the WA-RX-03-R are henceforward referred to as final products.) The European regulation applicable to the WA-TX-03-R and the WA-RX-03-R is the R&TTE Directive 1999/5/EC. The WA-TX-03-R and the WA-RX-03-R are intended to be used for the Radio Microphones defined in the ERC/REC 70-03 Annex 10 and for the Wireless Audio Applications in the ERC/REC 70-03 Annex 13 (EN 301 357*) The conformity assessment for the WA-TX-03-R and the WA-RX-03-R were completed in accordance with the R&TTE Directive Annex II (RX) & III (TX) procedures, and the Declaration of Conformity is attached to this manual. * NOTE: EN 301 357 defines the equipment covered by its standard and the output power limits depend on the equipment type. The WA-TX-03-R meets the output power limits allowed for all equipment types except for “in-vehicle cordless” and “personal cordless”. If the WA-TX-03-R is used for “in-vehicle cordless” or “personal cordless” equipment, the manufacturer is required to design the final product within the specified output power limit and to perform the conformity assessment of the final product to EN 301 357. Cautions related to regulatory compliance when embedding WA-TX-03-R/WA-RX-03-R 1. Antenna for the WA-TX-03-R The WA-TX-03-R is supplied without a dedicated antenna and the user is required to provide an antenna. The conformity assessment of the WA-TX-03-R was performed using Circuit Design’s evaluation board and antenna (1/4 lambda lead antenna). We recommend that you use our standard antenna (ANT-LEA-02 or ANT-RIG-02), or an antenna with equivalent characteristics and performance. For details about our evaluation boards and antennas, refer to www.cdt21.com or contact us. If you use an antenna other than the recommended antenna, further radio conformity assessment may be required. 2. Supply voltage of the WA-TX-03-R The WA-TX-03-R should be used within the specified voltage range (4.2 V to 6.0 V). 3. Enclosure To fulfill the requirements of EMC and safety requirements, the WA-TX-03-R and the WA-RX-03-R should be mounted on the circuit boards of the final products and must be enclosed in the cases of the final products. No surface of the WA-TX-03-R and the WA-RX-03-R should be exposed. 4. Cordless audio transmitter shutoff The WA-TX-03-R does not have automatic transmitter shutoff function in the module. The manufacturer of the final product is required to design the final product to have such function in accordance with EN 301 357. EMC requirements according to the R&TTE Directive Article 3.1b The ESD-test (Electro Static Discharge test) was not performed on the WA-TX-03-R and the WA-RX-03-R. The WA-TX-03-R and the WA-RX-03-R are designed for embedding in final products and rely on the enclosures of the final products to provide the necessary protection. The ESD test should be performed on the final products incorporating the WA-TX-03-R and the WA-RX-03-R. Safety requirements according to the R&TTE Directive Article 3.1a The WA-TX-03-R and the WA-RX-03-R rely on the final products to provide the electrical, mechanical, and fire enclosure requirements. The nominal supply voltage of the WA-TX-03-R is 4.2 – 6.0V and the WA-RX-03-R is 3.0 V – 5.0 VDC. The worst input currents under normal operating conditions are 70mA and 45mA respectively. The final product should be capable of supplying these power requirements. The WA-TX-03-R and the WA-RX-03-R are entirely SELV (Separated Extra Low Voltage) when the supply input from the final product is SELV, i.e. the WA-TX-03-R and the WA-RX-03-R are Class III equipment in which protection against electric shock relies on a supply from an SELV circuit and in which hazardous voltage is not generated. The WA-TX-03-R and the WA-RX-03-R should be installed in the final products so that the required creepage and clearance distances (within the final products) are maintained. Conformity assessment of the final product The manufacturer of the final product is responsible for the conformity assessment procedures of the final product in accordance with the R&TTE Directive. As to the conformity assessment of the R&TTE Directive Article 3.2 (Efficient use of the radio spectrum), the manufacturer of the final products incorporating the R&TTE assessed WA-TX-03-R and WA-RX-03-R will be exempted from its conformity assessment procedures. For details of how to use the conformity assessment of the WA-TX-03-R and the WA-RX-03-R, please consult the relevant authorities or accredited certification bodies. Notification of the final product The notification required by R&TTE Directive Article 6 (4) is not necessary if the final product is used in the harmonized frequency band and is classified as Class-1 equipment. If the final product is not used in the harmonized frequency band and is classified as Class-2 equipment, the manufacturer of the final product has a duty to notify the relevant radio regulatory authorities in the countries where the final product is sold. Exemption clause Circuit Design, Inc does not guarantee the accuracy of the above mentioned information about the conformity assessment and notification of the final product. Directives, technical standards, principles of operation and the like may be interpreted differently by the authorities in each country. Also the national laws and restrictions vary with the country. In case of doubt or uncertainty, we recommend that you check with the authorities or official certification organizations of the relevant countries
