FCC Certification Requirements.

According to the definition of mobile and fixed device is described in Part 2.1091(b), this
device is a mobile device.
And the following conditions must be met:
1. This Modular Approval is limited to OEM installation for mobile and fixed applications
only. The antenna installation and operating configurations of this transmitter, including
any applicable source-based time- averaging duty factor, antenna gain and cable loss
must satisfy MPE categorical Exclusion Requirements of 2.1091.
2. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and
the user’s body and must not transmit simultaneously with any other antenna or
transmitter.
3. A label with the following statements must be attached to the host end product: This
device contains FCC ID: 2AGN8-WF863.
5. This module must not transmit simultaneously with any other antenna or
transmitter
6. The host end product must include a user manual that clearly defines operating
requirements and conditions that must be observed to ensure compliance with current
FCC RF exposure guidelines.
For portable devices, in addition to the conditions 3 through 6 described above, a
separate approval is required to satisfy the SAR requirements of FCC Part 2.1093
If the device is used for other equipment that separate approval is required for all other
operating configurations, including portable configurations with respect to 2.1093 and
different antenna configurations.
For this device, OEM integrators must be provided with labeling instructions of finished
products. Please refer to KDB784748 D01 v09r01, section 8. page 2/5 last two

paragraphs:
A certified modular has the option to use a permanently affixed label, or an electronic
label. For a permanently affixed label, the module must be labeled with an FCC ID -
Section 2.926 (see 2.2 Certification (labeling requirements) above). The OEM manual
must provide clear instructions explaining to the OEM the labeling requirements,
options and OEM user manual instructions that are required (see next paragraph).
For a host using a certified modular with a standard fixed label, if (1) the module’s FCC
ID is not visible when installed in the host, or (2) if the host is marketed so that end
users do not have straightforward commonly used methods for access to remove the
module so that the FCC ID of the module is visible; then an additional permanent label
referring to the enclosed module:“Contains Transmitter Module FCC ID: 2AGN8-WF863”
or “Contains FCC ID: 2AGN8-WF863” must be used. The host OEM user manual must
also contain clear instructions on how end users can find and/or access the module and
the FCC ID.
The final host / module combination may also need to be evaluated against the FCC
Part 15B criteria for unintentional radiators in order to be properly authorized for
operation as a Part 15 digital device.
The user’s manual or instruction manual for an intentional or unintentional radiator shall
caution the user that changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment. In
cases where the manual is provided only in a form other than paper, such as on a
computer disk or over the Internet, the information required by this section may be
included in the manual in that alternative form, provided the user can reasonably be
expected to have the capability to access information in that form.
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.
Changes or modifications not expressly approved by the manufacturer could void the
user’s authority to operate the equipment.
To ensure compliance with all non-transmitter functions the host manufacturer is
responsible for ensuring compliance with the module(s) installed and fully operational. For
example, if a host was previously authorized as an unintentional radiator under the
Declaration of Conformity procedure without a transmitter certified module and a module
is added, the host manufacturer is responsible for ensuring that the after the module is
installed and operational the host continues to be compliant with the Part 15B
unintentional radiator requirements.

IC statement
The host product shall be properly labelled to identify the modules within the host product.
The Innovation, Science and Economic Development Canada certification label of a
module shall be clearly visible at all times when installed in the host product; otherwise,
the host product must be labelled to display the Innovation, Science and Economic
Development Canada certification number for the module, preceded by the word
“Contains” or similar wording expressing the same meaning, as follows:
“Contains IC: 20888-WF863” or “where: 20888-WF863 is the module’s certification
number”.

Le produit hôte doit être correctement étiqueté pour identifier les modules dans le produit
hôte.
L'étiquette de certification d'Innovation, Sciences et Développement économique Canada
d'un module doit être clairement visible en tout temps lorsqu'il est installé dans le produit
hôte; sinon, le produit hôte doit porter une étiquette indiquant le numéro de certification
d'Innovation, Sciences et Développement économique Canada pour le module, précédé
du mot «Contient» ou d'un libellé semblable exprimant la même signification, comme suit:
"Contient IC: 20888-WF863" ou "où: 20888-WF863 est le numéro de certification du
module".
A label with the following statements must be attached to the host end product: This
device contains IC: 20888-WF863.
