4.1.3
CYWM6935PAEC
Correct Labeling:
If an end device containing a WirelessUSB CYWM6935PAEC
Radio Module will be sold or used in the USA, the enclosure
of the product must display a label with the following basic
elements:
Cypress Semiconductor Corporation has obtained regulatory
approvals for the CYWM6935PAEC to be used in specific
countries. CYWM6935PAEC was approved under the
“Modular Approval (MA) to the OEM.
The MA Grant provides that device manufacturers who incorporate CYWM6935PAEC as tested and approved can be
relieved from having to perform the Radio Regulatory certification portion of the respective agency certification.
The MA Grant is valid only in countries[1.] that recognize the
MA Grant certification process; the USA, Canada, Belgium,
Denmark, France, Finland, Germany, Italy, Netherlands,
Spain, Sweden, UK.

0122
In order to be able to take advantage of Cypress’s modular
certification in an end product, the following must be ensured:
1. Correct Application.
2. Correct Installation.
3. Correct labeling.
4.1.1
Correct Application:
If an end device containing WirelessUSB CYWM6935PAEC
Radio Module will be sold or used in Canada, the enclosure of
the product must display a label with the following basic
elements:
There are two types of application considered for
CYWM6935PAEC modules. The application types are defined
below:
This product contains Cypress WirelessUSB module

separation from the human body.
4.1.2
Correct Installation:
— Modules cannot be modified in any way.
— Modules must be used only in the operating range specified in the data sheets.
— Modules cannot be located within 20 cm of another intentional radiator in the system.
— It is recommended to use Antenna-A or equivalent. The
antenna gain and form factor should be equivalent to
Antenna-A.
— Must guarantee that end user cannot easily change antenna.
Note: Sidestepping these requirements is possible with
additional testing and/or recertification. However, modular
approval would no longer apply.
Document #: 001-07822 Rev. **
As of March 2006, Japan does not recognize the “Modular
Approval” certification. Regulatory certification for Japan
(TELEC) must be acquired through typical approval procedures. These approvals are the sole responsibility of the OEM.
Note: Even with modular approval, the end device still has to
be tested for digital emissions compliance with all agencies as
an electronic device. The modular approval only eliminates the
need to test for compliance on RF transmissions.
4.2
User Guide Information
Electronic device manufacturers using Cypress’s Modular
Approval are required to follow the below mentioned labeling
practice on the container in which the device is marketed or in
the product user’s guide. This should be in accompaniment
with other regulatory information. The text may be disbursed
according to language or geographic regions if desired, but the
exact text shown below must be maintained.
4.2.1
United States of America requirements:
The device shall bear the following statement in a conspicuous
location:
Page 5 of 10
PRELIMINARY
“This device complies with part 15 of the FCC rules.
Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and
(2)this device must accept any interference received,
including interference that may cause undesired
operation”.
When the device is so small or for such use that it is not
practical to place the statement specified under paragraph (a)
of this section on it, the information required by this paragraph
shall be placed in a prominent location in the instruction
manual or pamphlet supplied to the user or, alternatively, shall
be placed on the container in which the device is marketed.
However, the FCC identifier or the unique identifier, as appropriate, must be displayed on the device.
The users manual or instruction manual for an intentional or
unintentional radiator shall bear the following cautionary
statement:
Caution: Changes or modifications not expressly approved by
the party responsible for compliance could void the user’s
authority to operate the equipment.
FCC cerification and performance is valid only up to
power level PA5. It is advised not to use the module in
levels PA6 and PA7.
4.2.1.1 United States Regulatory Approval FCC Modular Approval (MA)
The requirements for FCC Modular Approval were released in
June 2000 in the FCC’s Public Notice: FCC Public Notice DA
00-1407, Part 15 Unlicensed Modular Transmitter Approvals.
Criteria for Modular Approval
In our OEM instructions it is recommend that the following
rules (required by FCC grants) be adhered to:
• Cypress FCC ID label must appear on the outside of their
product. FCC Public Notice DA 00-1407 instructs, "...if the
FCC ID is not visible when the module is installed inside
another device, then the outside of the device into which the
module is installed must also display a label referring to the
enclosed module. This exterior label can use wording such as
the following: “Contains Transmitter Module FCC
ID:XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any
similar wording that expresses the same meaning may be
used."
• No co-location with other transmitters is allowed. By
definition, co-location is when another radio or its antenna is
located within 20 cm of our radio and it can transmit simultaneously 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.
• Not withstanding the Modular Approval for the Radio Device
with associated interconnect and antennae, the end product
configuration must meet digital emissions compliance and
must be tested in accordance with FCC Part 15 requirements
confirming radiated emissions are within specified limits.Applicable sections include:
• Part 15 Section 15.109 Sub-paragraph A, Class B
Radiated Emission Limits.
These emissions tests can be conducted by the manufacturer
or by contacting an approved test facility equipped and
Document #: 001-07822 Rev. **
CYWM6935PAEC
certified accordingly. The results of these emissions tests are
not required to be submitted to the FCC 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 configuration.
• 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.
4.2.2
Industry Canadian Requirements and Regulatory
Approval
Industry Canada regulatory approval typically conforms to the
FCC in terms of emission levels and other regulatory requirements. It is the position of the Industry Canada agency that the
OEM is primarily responsible for ensuring end product
compliance. Cypress (Unigen) as grantee and supplier of the
module maintains responsibility for the Modular Approved
design.
Criteria for Modular Approval
In our OEM instructions it is recommend that the following
rules (required by Industry Canada) be adhered to:
• Cypress Industry Canada ID label must appear on the
outside of their product.If the Industry Canada ID is not
visible when the module is installed inside another device,
then the outside of the device into which the module is
installed must also display a label referring to the enclosed
module. This exterior label can use wording such as the
following: “Contains Transmitter Module Canadian Cert
No IC: XYZMODEL1” or “Contains Canadian Cert No IC:
XYZMODEL1.” Any similar wording that expresses the
same meaning may be used.
• No co-location with other transmitters is allowed. By
definition, co-location is when another radio or its antenna
is located within 20 cm of our radio and it can transmit simultaneously 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.
• Notwithstanding the Modular Approval for the Radio Device
with associated interconnect and antennae, the end product
configuration must meet digital emissions compliance and
must be tested in accordance Industry Canada RSS-210
(Low Power License-Exempt Radio communication
Devices) requirements confirming radiated emissions are
within specified limits. Applicable sections include:
• Part 15 Section 15.109 Sub-paragraph A, Class B Radiated Emission Limits.
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 Industry Canada 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 configuration.
• 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 harmonized (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.
Document #: 001-07822 Rev. **

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 definition, co-location is when another radio or its antenna is located within 20 cm of our radio and it can transmit simultaneously 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 European Union standards ETSI 300 328 (European Telecommunications 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 configuration.
• 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 recommended. Cypress assumes no responsibility for compliance of
the end-product configuration.
