“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 appro-

priate, 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 Ap-

proval (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 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.
• 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.Appli-

cable 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 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 require-

ments. 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 simul-

taneously 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 Ra-

diated 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.
