During the use of the module, please pay attention to avoid the influence of power amplifier, booster line, DC/DC circuit and other interference sources on the module, and avoid the formation of series circuit between the power supply loop of the module and the high-power circuit unit to reduce the interference B. If there are batteries, metal objects, LCD screens, speakers, etc. next to the module antenna, the distance from the antenna should be at least 15mm(as shown in the figure).

Pcb cloth board: because the metal will weaken the function of the antenna, when the module cloth board, it is forbidden to lay the ground and walk the line under the module antenna, if it can be hollowed out better. D. Regarding the use environment of WIFI, wireless signals are easily influenced by the surrounding environment, such as trees, metals and other obstacles will absorb wireless signals to a certain extent, so in practical application, the distance of data transmission will be affected to a certain extent 8 Reflow Temperature Profile Key features of the profile:
-Initial Ramp=1-2.5/sec to 175 equilibrium
-Equilibrium time=60 to 80 seconds
-Ramp to Maximum temperature (250)=3/sec Max
-Time above liquidus temperature(217): 45 - 90 seconds
-Device absolute maximum reflow temperature: 250 A3 WWW.C-CHIP.COM.CN 0755-29179480/81

: 0755-84736169 10 13 FCC regulatory compliance statement 15.19 Statement 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. 15.21 Information to user Warning: changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. List of applicable FCC rules:
47 CFR Part 15, Subpart C 15.203 47 CFR Part 15, Subpart C 15.205 47 CFR Part 15, Subpart C 15.207 47 CFR Part 15, Subpart C 15.209 47 CFR Part 15, Subpart C 15.247 47 CFR Part 2 2.1091 Summarize the specific operational use conditions This module can be used in IOT devices. For example, after installing the single module, the printer can be connected to the router through the wireless network. Within the WiFi coverage, the user can send various printing instructions from the smartphone or PC, which will be very convenient. The input voltage to the module is nominally 5V. Only the embedded integral antenna is allowed. Any other external antenna is prohibited. Limited module procedures This module is not a limited module. Trace antenna designs The antenna is not a trace antenna. RF exposure considerations This Module complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Antennas This module is tested with PCB antenna, and the Max. antenna gain is 0dBi. If you desire to increase antenna gain and either change antenna type or use same antenna type certified, a Class II permissive change application is required to be filed by us, or you (host manufacturer) can take responsibility through the change in FCC ID (new application) procedure followed by a Class II permissive change application. Label and compliance information Please notice that if the FCC identification number 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 FCC ID: 2AR7VC-3L any similar wording that expresses the same meaning may be used. 15.19 Labelling requirements shall be complied on end user device. Labelling rules for special device, please refer to 2.925, 15.19 (a)(5) and relevant KDB publications. For E-label, please refer to 2.935. Information on test modes and additional testing requirements The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. The module is limited to installation in mobile application, a separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and difference antenna configurations. Test software access to different test modes: Wifi Test Tool v1.4.0 Testing item, Frequencies, Transmit Power, Modulation Type, test Antennas can be selected on the test script instructions. Additional testing, Part 15 Subpart B disclaimer This modular transmitter is only FCC authorized for the specific rule parts listed on our grant, 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. Host manufacturer in any case shall ensure host product which is installed and operating with the module is in compliant with Part 15B requirements. Please note that For a Class B or Class A digital device or peripheral, the instructions furnished the user manual of the end-user product shall include statement set out in 15.105 Information to the user or such similar statement and place it in a prominent location in the text of host product manual. Original texts as following:
For Class B 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.
