OPERATION GUIDE
Regulatory compliance information
Regulatory compliance of the STD-302N-R
T
he STD-302N-R is designed for embedding in other equipment. (Products incorporating the STD-302N-R are
henceforward referred to as final products.)
The European regulation applicable to the STD-302N-R is the R&TTE Directive 1999/5/EC.The conformity
assessment for the STD-302N-R was completed in accordance with the R&TTE Directive Annex III procedures,
and the Declaration of Conformity is attached to this manual.
Note: The STD-302N-R 434MHz is intended to be used in all EU and EFTA countries.
There may be restrictions on the use of voice and audio applications in the following countries; FI, FR, HU, IT, LU,
LI, CH.
Cautions related to regulatory compliance when embedding the STD-302N-R
1. Duty cycle
The STD-302N-R is designed to be used for the Non-Specific Short Range Devices defined in the ERC/REC
70-03 Annex 1.
The STD-302N-R continuously emits carrier signals when power is supplied. The user must design the final
product to meet the requirements of the duty cycle as provided in the Regulatory parameters related to Annex 1
of the ERC/REC 70-03.
2. Antenna
The STD-302N-R is supplied without a dedicated antenna and the user is required to provide an antenna. The
conformity assessment of the STD-302N-R was performed using Circuit Design’s standard antenna ANT-LEA-
01 (1/4 lambda lead antenna), so we recommend using the ANT-LEA-01 antenna or an antenna with equivalent
characteristics and performance. For details about our standard antenna, 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.
3. Supply voltage
The STD-302N-R should be used within the specified voltage range (3.0 V to 5.5 V).
4. Enclosure
To fulfill the requirements of EMC and safety requirements, the STD-302N-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 STD-
302N-R should be exposed.
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 product incorporating the R&TTE assessed STD-302N-R will be exempted from its
conformity assessment procedures. For details of how to use the conformity assessment of the STD-302N-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.
*NOTE: In case the STD-302N-R 434MHz is used with more than a 10% duty, notification of the final product will
be required. A list of Class-1 equipment is available at http://www.ero.dk/.
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.
