This certification, documented under the grantee code 2AW97 and product code -D9, confirms the device's compliance with FCC regulations governing low-power transmitters and unintentional radiators operating below 1 GHz. The certification process was conducted by Shenzhen Xinwu Technology Limited in collaboration with Shenzhen Huaxia Testing Technology Co., Ltd. This article provides a detailed exploration of the technical background, certification details, and organizational information related to the D9 Smart Doorbell, based solely on the provided data.
Technical Background and Certification Overview
The D9 Smart Doorbell is a low-power wireless device designed to operate in the sub-1 GHz frequency range. The FCC certification process ensures that such devices meet specific technical standards to prevent interference with other radio services and maintain safety and reliability for users. The certification under grantee code 2AW97 confirms that the D9 Smart Doorbell adheres to these regulations.
The certification scope includes several categories, such as low-power transmitters below 1 GHz (excluding spread spectrum), unintentional radiators, and consumer ISM devices. These categories are defined in the FCC's Part 15 regulations, which specify the conditions under which devices can operate without a license. The D9 Smart Doorbell is categorized under these rules, allowing it to be marketed and used in the United States without requiring additional authorization.
The certification was conducted by Shenzhen Huaxia Testing Technology Co., Ltd., a testing firm responsible for verifying the device's compliance with technical standards. The firm's contact information, including the email address of Jack Ai, was provided in the documentation. This detail ensures transparency in the testing process and allows users to reach out for further information if needed.
The certification was ultimately approved by Jin Jiang, the vice president of Shenzhen Xinwu Technology Limited. This role underscores the level of oversight and responsibility associated with the certification process. The applicant's fax number and email address are also listed, providing additional points of contact for users or stakeholders seeking information about the device.

The contact information provided includes a fax number (0755-27784247) and an email address ([email protected]). These details are crucial for users or stakeholders who may have inquiries about the certification process or the device's specifications.
The testing firm, Shenzhen Huaxia Testing Technology Co., Ltd., also provided contact information, including Jack Ai's email address ([email protected]). This information ensures that users can reach out to the testing firm for further details or clarification regarding the certification process.
Certification Process and Technical Standards
The FCC certification process involves rigorous testing and evaluation to ensure that devices meet the required technical standards. For the D9 Smart Doorbell, this process included testing for unintentional radiators and low-power transmitters operating below 1 GHz. These tests are essential to confirm that the device does not emit excessive electromagnetic interference (EMI) that could disrupt other electronic devices or radio services.
The certification under grantee code 2AW97 confirms that the D9 Smart Doorbell complies with the FCC's Part 15 rules, which govern the operation of low-power transmitters and unintentional radiators. These rules specify the maximum allowable power levels, frequency ranges, and other technical parameters that devices must adhere to. By meeting these standards, the D9 Smart Doorbell ensures that it can be used safely and reliably in various environments.
The certification also covers consumer ISM (Industrial, Scientific, and Medical) devices. ISM devices are used in a wide range of applications, from medical equipment to industrial machinery. The inclusion of consumer ISM devices in the certification scope indicates that the D9 Smart Doorbell is designed to operate in environments where such devices are commonly used. This classification ensures that the device does not interfere with the operation of other ISM devices and vice versa.
Compliance and Safety Considerations
Compliance with FCC regulations is essential for ensuring the safety and reliability of wireless devices. The D9 Smart Doorbell's certification under grantee code 2AW97 confirms that it meets the necessary safety standards. These standards are designed to protect users from potential health risks associated with exposure to electromagnetic fields (EMFs) and to ensure that the device does not interfere with other electronic devices.
The certification process involves testing the device's emissions to ensure that they fall within the acceptable limits defined by the FCC. This includes testing for both intentional and unintentional radiators. Intentional radiators are devices designed to emit radio waves, while unintentional radiators are devices that may emit radio waves as a byproduct of their operation. The D9 Smart Doorbell is classified as an unintentional radiator, and its emissions must be kept within the limits specified by the FCC.
In addition to emissions testing, the certification process also includes testing for electromagnetic compatibility (EMC). EMC testing ensures that the device can operate in its intended environment without causing interference to other devices and without being affected by interference from other sources. This is particularly important for wireless devices like the D9 Smart Doorbell, which operate in environments with a high density of electronic devices.
Conclusion
The FCC certification of the D9 Smart Doorbell under grantee code 2AW97 confirms that the device complies with the necessary technical and safety standards. The certification process, conducted by Shenzhen Huaxia Testing Technology Co., Ltd., ensures that the device meets the requirements for low-power transmitters, unintentional radiators, and consumer ISM devices. The involvement of Shenzhen Xinwu Technology Limited, the applicant for the certification, underscores the company's commitment to compliance and safety.
For users and stakeholders, the certification provides assurance that the D9 Smart Doorbell is a reliable and safe device that can be used in various environments without causing interference or posing health risks. The detailed contact information provided for both the applicant and the testing firm ensures that users can seek further information or clarification if needed.
As the demand for smart home devices continues to grow, the certification of such devices by regulatory bodies like the FCC plays a crucial role in ensuring their safety and reliability. The D9 Smart Doorbell's certification is a testament to the company's adherence to these standards and its commitment to providing high-quality, compliant products to consumers.
