Federal Communications Commission (FCC) 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. 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: z Reorient or relocate the receiving antenna. z Increase the separation between the equipment and receiver. z Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. z Consult the dealer or an experienced radio/TV technician for help. Warning: Changes or modifications made to this device not expressly approved by Hamedata Technology Co., Limited may void the FCC authorization to operate this device. Note: The manufacturer is not responsible for any radio or tv interference caused by unauthorized modifications to this equipment. Such modifications could void the user’s authority to operate the equipment. This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and any part of your body.

I understand the following FCC requirements: 1. Devices subject to the DoC procedure are required to be tested to show compliance with the FCC technical regulations by a recognized accredited testing laboratory. The testing laboratory must be accredited by a Commission approved accreditation body or designated under the terms of a government-to-government Mutual Recognition Agreement (MRA). A listing of those accredited testing laboratories that have been recognized by the Commission is published on the FCC Webpage: https://apps.fcc.gov/oetcf/eas/reports/TestFirmSearch.cfm (Select the "accredited" option to search for FCC recognized accredited test firms.) 2. Test facilities located in countries, where the U.S. does not have an operational Telcom MRA are not recognized by the FCC to test for the DoC procedure. 3. Pt 2.1077 contains the list of information that must be included in the Declaration of Conformity, which must be supplied with each product sold. The DoC compliance info shall be included in the User’s Manual or as a separate sheet. The info must contain the name, address, and phone number of the responsible party, which must be located within the United States. According to 2.909(c)(2), the responsible party is either the Manufacturer or if the product is imported the Importer. Sincerely, Zuo Xinrong/Manager 4. FCC DOC is doing at FCC recognized and authorized MRA lab and FCC DOC will be issued before sell.
