3、Circuit Description
WIFI module has an independent power management system, and
the system provides a high quality of power supply for the whole
module. The Excellent matching circuit in RF-Front ensures that the
signal has minimal signal loss and radiation. Oscillator Y1 provides the
IC U1 with the required oscillation frequency to enable the IC U1 to
work normally. The IC U1 provides the interfaces for a variety of
peripherals (Timer, PWM, Interrupt, AD, the Debug) from the module
to the baseboard. Each peripheral that connects to the MCU I/O pins
can choose between two different I/O pin locations with the provided
flexibility in various applications.
Hereby, [Name of manufacturer], declares that this [type of
equipment] is in compliance with the essential requirements and other
relevant provisions of RE Directive 2014/53/EU. A copy of the full DoC
is attached.

FCC KDB 996369 D03 for module certification:
1. List of applicable FCC rules and Canada rules:
The module complies with FCC Part 15.247, and Canada RSS-247.
2. Summarize the specific operational use conditions:
The module has been certified for Fix/Mobile applications. The host product
operating conditions must be such that there is a minimum separation
distance of 20 cm (or possibly greater than 20 cm) between the antenna
radiating structures and nearby persons. The host manufacturer is obligated
to confirm the use conditions of the host product to ensure that distance
specified in the instructions is met. In this case the host product is classified
as either a mobile device or a fixed device for RF exposure purposes. This
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
3. Limited module procedures:
Not applicable.
4. Trace antenna designs:
Not applicable.
5. RF exposure considerations:
This equipment complies with FCC’s and IC’s RF radiation exposure limits set forth for
an uncontrolled environment. The antenna(s) used for this transmitter must be
installed and operated to provide a separation distance of at least 20 cm from all
persons and must not be collocated or operating in conjunction with any other

antenna or transmitter. Installers must ensure that 20cm separation distance will be
maintained between the device and users.
DÉCLARATION D’IC SUR L’EXPOSITION AUX RADIATIONS:
Cet appareil est conforme aux limites d’exposition au rayonnement RF stipulées par la
FCC et l’IC pour une utilisation dans un environnement non contrôlé. Les antennes
utilisées pour cet émetteur doivent être installées et doivent fonctionner à au moins
20 cm de distance des utilisateurs et ne doivent pas être placées près d’autres
antennes ou émetteurs ou fonctionner avec ceux-ci. Les installateurs doivent
s’assurer qu’une distance de 20 cm sépare l’appareil des utilisateurs.
Note: the OEM product manuals must include a statement in order to alert the users
of FCC RF exposure compliance.

NOTE: The manufacturer is not responsible for any radio or TV interference caused by
unauthorized modifications or changes to this equipment. Such modifications or
changes could void the user’s authority to operate the equipment.
Warning: Changes or modifications to this unit not expressly approved by the party
responsible for
compliance could void the user’s authority to operate the equipment.
NOTE: 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 into 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.

GRJW05-J3 Modules. Below is the contents that must be included on this label.
OEM Labeling Requirements:
NOTICE: The OEM must make sure that FCC labeling requirements are met. This
includes a clearly
visible exterior label on the outside of the final product housing that displays the
contents shown in
below:
Contains FCC ID: 2ADAP-GRJWB05J

8. Information on test modes and additional testing requirements:
When testing host product, the host manufacture should follow FCC KDB Publication
WiFi Module User
Manual

996369 D04
Module Integration Guide for testing the host products. The host manufacturer may
operate their
product during the measurements. In setting up the configurations, if the pairing and
call box options
for testing does not work, then the host product manufacturer should coordinate
with the module manufacturer for access to test mode software. For wireless LAN,
the product under test is set into a link/association with a partnering WLAN device,
as per the normal intended use of the product. To ease testing, the product under
test is set to transmit at a high duty cycle, such as by sending a file or streaming some
media content. Alternatively, a Wi-Fi test set may be used. Simultaneously
transmitting modules installed in the host should be all active.
9. Additional testing, Part 15 Subpart B disclaimer:
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part
15.247) list on the
grant, and that the host product manufacturer is responsible for compliance to any
other FCC rules that apply to the host not covered by the modular transmitter grant
of certification. The final host product still requires Part 15 Subpart B compliance
