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. This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. 15.105 Information to the user.
(b) For a Class B digital device or peripheral, the instructions furnished the user shall include the following or similar statement, placed in a prominent location in the text of the manual:
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. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator and your body. Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end user. The final end product must be labelled in a visible area with the following:
Contains Transmitter Module 2A3E4-JHY32U Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 List of applicable FCC rules This module operates on the 2400-2483.5MHz band, and is within U.S. FCC part 15.247 standard. 2.3 Specific operational use conditions Operating Frequency 2402MHz~2480MHz JHY32-WROOM-32U Is a universal Wi-Fi+BT+BLE MCU module, with the industry's competitive package size and ultra-low energy consumption technology, designed for mobile devices and Internet of Things applications, users can connect their physical devices to Wi-Fi and Bluetooth wireless network, network communication, networking functions. To maintain compliance with FCC RF exposure requirements, Please use the antenna provided with the product. 2.4 Limited module procedures not applicable .Please refer to the manual for usage scenarios Single Modular Approval Request 2.5 Trace antenna designs not applicable .without trace antenna 2.6 RF exposure considerations RF exposure requirements are fulfilled for mobile configuration. This equipment should be installed and operated with minimum distance between 20cm the radiator your body The installation of the module is restricted to mobile host devices For portable applications OEM integrators need SAR evaluation and an own FCC ID. The module comes with permanently attached antennas. The spurious emission requirements are fulfilled (see 2.7 Antennas attached test report). Antenna Type Rod Antenna Antenna Gain 2 dBi 2.8 Label and compliance information See Guidelines for Labeling and User Information for RF Devices KDB Publication 784748. host product manufacturers that they need to provide a physical or e-label stating Contains FCC ID 2A3E4-JHY32U with their finished product 2.9 Information on test modes and additional testing requirements The test mode in the report is the module's maximum transmitting power emission for testing Test modes should take into consideration different operational conditions for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product. 2.10 Additional testing, Part 15 Subpart B disclaimer the modular transmitter is only FCC authorized for the specific rule parts (FCC Part15.247) listed 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. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
