CERPASS TECHNOLOGY (SUZHOU)CO., LTD Report No.: SEDL1702032 MPE Report According to FCC CFR Title 47 Part 15 Subpart C (15.247) Applicant : YEALINK (XIAMEN) NETWORK TECHNOLOGY CO., LTD. 309, 3th Floor, No.16, Yun Ding North Road, Huli District, Xiamen City, Address : Fujian, China Manufacturer : YEALINK (XIAMEN) NETWORK TECHNOLOGY CO., LTD. 309, 3th Floor, No.16, Yun Ding North Road, Huli District, Xiamen City, Address : Fujian, China Equipment : Media IP Phone Model No. : SIP-T52S  The test result refers exclusively to the test presented test model / sample.,  Without written approval of Cerpass Technology (Suzhou) Co.,Ltd. the test report shall not be reproduced except in full.  The EUT is also considered as a kind of computer peripheral, because the connection to computer is necessary for typical use. It has been verified to comply with the requirements of FCC Rules and Regulations Part 15. The test report has been issued separately.  The test report must not be used by the clients to claim product certification approval by NVLAP or any agency of the Government.

The maximum output power is 3.34dBm (0.000216W) at 2402MHz (with numeric 1.32antenna gain.) for2.4G band 2. DTS device is not subject to routine RF evaluation; MPE estimate is used to justify the compliance. 3. For mobile or fixed location transmitters, no SAR consideration applied. The maximum power density is 1.0 mW/cm2 even if the calculation indicates that the power density would be larger. *Note: Simultaneous transmission is not applicable for this EUT. h Cerpass Technology (Suzhou) Co., Ltd Issued Date : Mar. 13 ,2017 Report format Revision 01 Page No. : 3 of 4
