• Cypress module can only be installed by the OEM and not 

by the user. It should not be installed in a user accessible 

location.

• Any modifications to the radio will void the user's authority 

to operate the equipment. The OEM must not modify any 

aspect of the radio's mechanical and electrical configu-

ration.

• The OEM must include compliance information in their user 

information.

• Although no additional regulatory work may be required for 

the radio, the host device is probably subject to other FCC 

authorizations as a digital device. DoC authorization is 

required for PCs and peripherals; verification is required for 

most other digital devices.

Note:

Industry Canada generally follows the guidelines of the FCC

for emissions level requirements. FCC end-product

compliance certification results may be used to satisfy Industry

Canada requirements. Please consult the Industry Canada,

RSS 210 specifications to confirm interagency compliance. If

comparable FCC testing has not been performed or if the

specifications are not cross compliant, RSS 210 testing will be

required.

4.2.3

European Union Requirements and Regulatory 

Approval

The requirements for EU Regulatory Approval were released

in April 2000 in the EU R&TTE Directive.
This directive supports self directed testing and certification for

“harmonized” bands within OEM facilities or by third party. In

the case of WirelessUSB, standards have become harmo-

nized (although frequencies are not). The R&TTE directive no

longer requires a Technical Construction File however;

frequency notification to EU countries is still applicable.
Article 6 of the R&TTE directive states: “

The manufacturer or

the person responsible for placing the apparatus on the

market provides information for the user on the intended

use of the apparatus, together with the declaration of

conformity to the essential requirements.

Ensuring regulatory compliance of the end product is the sole

responsibility of the OEM.
Cypress maintains responsibility for conformance of the

CYWM6935PAEC, the interconnect, and the antennae as the

manufacturer.
The R&TTE directive maintains that first level compliance be

reviewed by a “Notified Body” prior to general product

marketing. This is not mandatory, but reduces the risk of the

product being challenged for non-compliance. Although not

specifically stated in the R&TTE Directive, corrections of

noncompliance issues are the responsibility of the end product

manufacturer.

Criteria for Modular Approval

In our OEM instructions it is recommended that the following

rules (required by ETSI) be adhered to:

• No co-location with other transmitters is allowed. By defini-

tion, co-location is when another radio or its antenna is lo-

cated within 20 cm of our radio and it can transmit simulta-

neously with your radio. Only the antenna(s) that were 

certified with your radio may be used. Other antennas may 

be used only if they are of the same type (e.g. yagi, dipole, 

patch) and have the same or lower gain.

• The end-product configuration must meet digital emissions 

compliance and must be tested in accordance with the Eu-

ropean Union standards ETSI 300 328 (European Telecom-

munications Standard for 2.4 GHz ISM band Emissions) and 

ETSI 300 826 (Electromagnetic Compatibility).

Detailed European Union regulatory standards documentation

may be obtained from the following URL:
http://europa.eu.int/comm/enterprise/rtte/infor.htm
These emissions tests can be conducted by the manufacturer

or by contacting an approved test facility equipped and

certified accordingly. The results of these emissions tests are

not required to be submitted to the ETSI or Cypress, but

should be kept on file by the OEM.

• Cypress module can only be installed by the OEM and not 

by the user. It should not be installed in a user accessible 

location.

• Any modifications to the radio will void the user's authority 

to operate the equipment. The OEM must not modify any 

aspect of the radio's mechanical and electrical configu-

ration.

• The OEM must include compliance information in their user 

information.

• Although no additional regulatory work may be required for 

the radio, the host device is probably subject to other FCC 

authorizations as a digital device. DoC authorization is 

required for PCs and peripherals; verification is required for 

most other digital devices.

Note:

The European Union generally follows the guidelines of the

FCC for emissions level requirements. FCC end-product

compliance certification results, if available, may be used to

satisfy EU requirements (Substitution Method). Please consult

the ETSI 300 328 specifications to confirm inter-agency

compliance. If comparable FCC testing has not been

performed or if the specifications are not cross compliant,

ETSI 300 328 testing will be required. Additionally, testing to

the ETSI 301 489-17 (immunity testing) is strongly recom-

mended. Cypress assumes no responsibility for compliance of

the end-product configuration.
