OPERATION GUIDE
Regulatory Compliance Information
Declaration of Conformity
Hereby, Circuit Design, Inc. declares that t
he WA-TX-03S and WA-RX-03S are in compliance with RE Directive
(2014/53/EU).
The full text of the EU Declaration of Conformity is available at www.circuitdesign.jp.
Cautions related to regulatory compliance when embedding WA-TX-03S/WA-RX-03S
1. Output power of the WA-TX-03S
EN 301 357 defines the equipment covered by its standard and the output power limits depend on the
equipment type.
The WA-TX-03S meets the output power limits allowed for all equipment types except for “in-vehicle
cordless” and “personal cordless”. If the WA-TX-03S 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.
2. Antenna for the WA-TX-03S
The WA-TX-03S is supplied without a dedicated antenna.
The conformity assessment of the WA-TX-03S 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.circuitdesign.jp or contact us. If you use an antenna other
than the recommended antenna, further radio conformity assessment may be required.
3. Supply voltage of the WA-TX-03S
The WA-TX-03S should be used within the specified voltage range (4.2 V to 6.0 V).
4. Enclosure
To fulfill the requirements of EMC and safety requirements, the WA-TX-03S and the WA-RX-03S 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-03S and the WA-RX-03S should be exposed.
5. Cordless audio transmitter shutoff
The WA-TX-03S does not have the 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.
Conformity assessment of the final product
The manufacturer of the final system needs to conduct full EMC testing in the final configuration and also ensure
the final product fulfills the safety requirements and is also responsible for the conformity assessment procedures
of the final product in accordance with the RE Directive.
