User Guide Information

Electronic device manufacturers using Cypress Envirosystems modular approval are
required to place the below text in their product user’s guide 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.

§ 15.19 Labeling Requirements:

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 practicable 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.

§15.21 Statement - for all intentional and unintentional radiators.

Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

§15.105 Statement (for digital devices)

For a Class B digital device or peripheral, the instructions furnished the user shall
include the following or similar statement, placed in a prominent location in the text of the
manual:

This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment to an outlet on a circuit different from that to

which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.
Note: Changes or modifications not expressly approved by the manufacturer
responsible for compliance could void the user’s authority to operate the
equipment. 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

Cypress Envirosystems OEM User Manual Page 5

Rev02

interference and (2) this device must accept any interference received,
including interference that may cause undesired operation.

RF Exposure info:

This equipment complies with the FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 20 centimeters between the radiator and your body.

This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.

The antennas used for this transmitter must be installed to provide a separation distance
of at least 20cm from all persons and must not be located or operating in conjunction
with any other antenna or transmitter.

Antenna Support:

Up to 7.4dBi Omni tested under FCC part 15.247 rules.
Certified with:

• NKG SF-245WR (7.4dBi)

• Centurion NanoBlue-FL04 (2.0dBi)

Co-location of Additional Transmitters

Digital Electronic Devices manufacturers using this MA grant should refer to Appendix B
(FCC Grant #) for end-products using two or more co-located RF transmitters. This grant
states:

“This modular transmitter is approved for use in Digital Electronic Devices
and may operate in conjunction with other mobile and portable transmitters in
the same device; provided, the other mobile and portable transmitters have
satisfied the appropriate RF exposure requirements contained in the FCC
rules. The grantee must also provide Digital Electronic Device integrators, or
end users if marketed directly to end users, with installation and operating
instructions for satisfying RF exposure requirements. The Grantee must
inform second manufacturers/installers that in order for this module to be
operated in any configuration other than that permitted in the preceding
sentences, a separate FCC equipment authorization must be obtained for
each device into which this module is installed.“

This modular approval is granted provided Digital Electronic Devices manufacturers
assume responsibility for ensuring that other transmitters operating in conjunction with
the WiFi3309701 comply with RF exposure requirements associated with their use. The
use of one or more additional RF transmitters will require review by the FCC and may
require end-product recertification, including the WiFi3309701 to ensure emissions
compliance and RF safety. It is the sole responsibility of the Digital Electronic Device
manufacturer to obtain end-product regulatory compliance for configurations including
two or more RF transmitters.

Product Labeling Requirements

FCC product labeling requirements stipulate an FCC label, including specific text, be
placed on the device containing the WiFi3309701 module. The product label must
include the following text and must be affixed to the exterior of the OEM’s product.

“Contains FCC ID: W3I-WIFI3309701”

Industry Canadian 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 primarily responsibility for ensuring end product compliance.
Cypress Envirosystems as grantee and supplier of the module maintains responsibility
for the Modular Approved design.

Product Labeling Requirements

Industry Canada product labeling requirements stipulate that specific text be placed on
the device containing the WiFi3309701 module. The product label must include the
following text and must be affixed to the exterior of the OEM’s product. The same
information must be included in the product user manual.

“Contains IC: 8266A-WIFI3309701”
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB-

003 du Canada.

Europe

Regulatory Marking

The equipment shall be marked, where applicable, in accordance with CEPT/ERC
Recommendation 70-03 or Directive 1999/5/EC, whichever is applicable. Where this is
not applicable, the equipment shall be marked in accordance with the National
Regulatory requirements.

CE Marking

The equipment shall be marked in a visible place. This marking shall be legible and
durable.

In cases where the devices are too small to carry legible marking, it is sufficient to
provide the relevant information in the user’s manual and on the product packaging.
