Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ181011003-00B FCC §15.247 (i) & §1.1307 (b) (1) & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to subpart 15.247 (i) and subpart 1.1307 (b)(1), 2.1091 systems operating under the provisions of this section shall be operated in a manner that ensures the public is not exposed to RF energy level in excess of the communication guidelines.

G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor, is normally numeric gain. R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) FCC Part 15.247 Page 12 of 45

Note 2: Please refer to the report of FCC ID: UDV-1009092010008 for the max tune-up power. Note 3: The Wi-Fi and Bluetooth have its own module, so they can transmit at the same time. = 0.079/0.55 + 0.028/1 + 0.001/1= 0.173<1.0 Note: To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons.
