Block Diagram WIFI module has an independent power management system, and the system provides 3 a high quality of power supply for the whole module. Flash is used for the external expansion memory. The Excellent matching circuit in RF-Front ensures that the signal has minimal signal loss and radiation. The MCU 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. 4. Pin Definition Figure 2.

5.1 List of applicable FCC rules and Canada rules:
The module complies with FCC Part 15.247, and Canada RSS-247. 5.2 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. 5.3 Limited module procedures:
Not applicable. 5.4 Trace antenna designs:
Not applicable. 5.5 RF exposure considerations:
This equipment complies with FCCs and ICs RF radiation exposure limits set forth for an uncontrolled environment. The antenna(s) used for this transmitter must be installed and 5 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. DCLARATION DIC SUR LEXPOSITION AUX RADIATIONS:
Cet appareil est conforme aux limites dexposition au rayonnement RF stipules par la FCC et lIC pour une utilisation dans un environnement non contrl. Les antennes utilises pour cet metteur doivent tre installes et doivent fonctionner au moins 20 cm de distance des utilisateurs et ne doivent pas tre places prs dautres antennes ou metteurs ou fonctionner avec ceux-ci. Les installateurs doivent sassurer quune distance de 20 cm spare lappareil des utilisateurs. Note: the OEM product manuals must include a statement in order to alert the users of FCC RF exposure compliance. 5.6 Antennas:
Type Gain Impedance PCB type F Antenna 1.0 dBi 50 The antenna is permanently attached, cant be replaced. 5.7 Label and compliance information:
Application Min Separation Fixed/Mobile 20 cm. 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. 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 6 could void the users authority to operate the equipment. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the users 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. ISED statements:
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canadas licence-exempt RSS(s). Operation is subject to the following two conditions:

The system integrator must place an exterior label on the outside of the final product housing the GRJW06-J 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:
Model: GRJW06-J Contains FCC ID: 2ADAP-GRJW06J Contains IC: 12478A-GRJW06J 5.8 Information on test modes and additional testing requirements:
When testing host product, the host manufacture should follow FCC KDB Publication 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. 8 5.9 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 testing with the modular transmitter installed when contains digital circuity. 9 Gree Electric AppliancesInc. of Zhuhai Adresse:West Jinji Rd,Qianshan,Zhuhai,Guangdong,China,519070 10
