Conformity assessment of the final product*
(*Circuit design’s RF modules are designed for embedding in other equipment. Products incorporating RF modules and modems are hereinafter referred to as final products)
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 radio module will be exempted from its conformity assessment procedures. For details of how to use the conformity assessment of the RF module, 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. A list of Class-1 equipment is available on the web site of ERO 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.

This is a brief overview of the regulatory information concerning license exempt low power radio related to Circuit Design's radio modules.
The following two categories represent the major license exempt low power radio categories.

Radio stations operating with extremely low power of emission

Radio stations that emit very low power. They are excluded from the category that requires technical regulation conformity certification, but they are very low power stations.

Specified low-power radio stations

To use radio with higher output power, there are several categories of license exempt low power radio, but they require technical regulation conformity certification. Specified low-power radio station is the category that fits most of Circuit Design's radio modules. It allows emission up to 10 mW.

Radio stations operating with extremely low power of emission
This is the category for which there is no need for technical regulation conformity certification.
Only the maximum field strength is specified as shown below.
Typical products used in this category are vehicle keyless entry systems that have operating ranges of only a few meters. Maximum field strength allowed in this category is very low compared with the RF power allowed by FCC part 15 or European regulation. The practical operation range achievable with such low power is very limited.

Figure:Tolerance of the electric field intensity of extremely low power radio stations at a distance of 3 m

Specified low power radio station
This is the part where 1-10 mW of maximum RF power is allowed.
Generally, it requires the fulfillment of all of the following conditions.

1. Antenna power of 10 mW or less
2. Use of radio type and frequency as specified in the ministerial ordinance of the Ministry of Public
Management, Home affairs, Post and Telecommunications (MPMHPT).
3. Not disturbance of the operations of other radio stations.
4. Only use of radio equipment with Technical Regulation Conformity Certification.

Among the many standards for specified low power radio stations, the specific standard applicable to Circuit Design's radio modules in the 400 MHz and 1200 MHz bands is RCR T-67. It covers most low power radio applications. It specifies applications in the title as "Telemeter, Tele-control and Data Transmission Radio equipment for Specified Low Power Radio Stations”. The following table summarizes the specifications of the standard.

All the technical information concerning products for the Japanese market is in Japanese.
Circuit Design's radio modules in 434 MHz and 869 MHz cannot be used in Japan as they are not compliant with Japanese radio regulations.

Who offers technical conformity certification of radio products in Japan?
Circuit Design does not offer conformity certification of customer's products in Japan.
It is recommended to use Circuit Design's radio modules that already have certification in Japan. This is the easiest way if the modules are adaptable to your system.
To get technical conformity certification of your own products with RF parts, it is recommended to find a partner in Japan who offers conformity certification procedures for your products in Japan. As another way, it is recommended to use a European test laboratory that offers certification for Japan. As far as we know, the following test laboratory in Europe is authorized to issue Japanese approvals for radio equipment including RCR STD-T67.

The following list shows links to the relevant pages of the radio regulatory authority where you can find the technical standards and information for certification of your own products.

Please note that these links may not always remain valid. This list is correct as of May 2003.

The limits of output power, bandwidth and harmonics, and frequency vary throughout the world. Circuit Design does not supply pre-assessed radio modules for the USA and other parts of the world except for Europe and Japan.
