GUANGDONG SYMA MODEL AIRCRAFT INDUSTRIAL CO., LTD Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Date: SUBJECT: FCC Application for FCC ID: QV7-GC88752-117 To Whom It May Concern: We, the undersigned, hereby authorize Max Zhang at Shenzhen Tongzhou Testing Co.,Ltd. on our behalf, to apply to the Federal Communications Commission on our equipment. Any and all acts carried out by Shenzhen Tongzhou Testing Co.,Ltd. on our behalf shall have the same effect as acts of our own. This is to advise that we are in full compliance with the Anti- Drug Abuse Act. We, the applicant, are not subject to a denial of federal benefits pursuant to Section 5301 of the Anti-Drug Act of 1988, 21 USC853a, and no party to the application is subject to a denial of federal benefits pursuant to that section.

Label Location 20*15mm FCC ID: QV7-GC88752-117 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.

FCC ID:QV7-GC88752-117 Page 1 of 2 This report shall not be reproduced except in full, without the written approval of Shenzhen Tongzhou Testing Co.,Ltd RADIO FREQUENCY EXPOSURE Limit According to section B.4 of 447498 D04 Interim General RF Exposure Guidance v01 SAR-based thresholds are derived based on frequency, power, and separation distance of the RF source. The formula defines the thresholds in general for either available maximum time-averaged power or maximum time-averaged ERP, whichever is greater. If the ERP of a device is not easily determined, such as for a portable device with a small form factor, the applicant may use the available maximum time-averaged power exclusively if the device antenna or radiating structure does not exceed an electrical length of λ/4. As for devices with antennas of length greater than λ/4 where the gain is not well defined, but always less than that of a half-wave dipole (length λ/2), the available maximum time-averaged power generated by the device may be used in place of the maximum time-averaged ERP, where that value is not known. The separation distance is the smallest distance from any part of the antenna or radiating structure for all persons, during operation at the applicable ERP. In the case of mobile or portable devices, the separation distance is from the outer housing of the device where it is closest to the antenna. The SAR-based exemption formula of § 1.1307(b)(3)(i)(B), repeated here as Formula (B.2), applies for single fixed, mobile, and portable RF sources with available maximum time-averaged power or effective radiated power (ERP), whichever is greater, of less than or equal to the threshold Pth (mW). This method shall only be used at separation distances from 0.5 cm to 40 cm and at frequencies from 0.3 GHz to 6 GHz (inclusive). Pth is given by Formula (B.2). Where and f is in GHz, d is the separation distance (cm), and ERP 20cm is per Formula (B.1).

The Maximum Erp is used for Routine Evaluation Exemption according to B.4 of 447498 D04 Interim General RF Exposure Guidance v01. So, the SAR evaluation is not required.
