Manufacturer 1523 26th Street, Santa Monica CA 90404, United States Product Type Ring Doorbell V2 Trade Name Ring Model Number Ring Video Doorbell 2 FCC ID 2AEUPBHARG043 Frequency Range Operate Band Frequency Range (MHz) IEEE 802.11b / 802.11g / 802.11n 2.4 GHz 20 MHz 2412 - 2462 Type Max. Gain (dBi) Antenna Information Dipole Antenna 1.96 Antenna Delivery IEEE 802.11b / 802.11g / 802.11n 2.4 GHz 20 MHz: 1 TX 2 RF Evaluation 0.016 mW/cm Temperature Range -20 ~ +50 °C The above equipment was tested by A Test Lab Techno Corp. For compliance with the requirements set forth in 47 CFR § 2.1091 / 47 CFR § 1.1310. The results of testing in this report apply only to the product/system, which was tested. Other similar equipment will not necessarily produce the same results due to production tolerance and measurement uncertainties ©2017 A Test Lab Techno Corp. Report Number: 1901FS15 Page 3 of 6

2. Human Exposure Assessment Due to the design and installation of this product, it is not possible to conduct SAR evaluation. This is because client either manufactures or supplies the antenna(s) that will be used in the installation of this product. Therefore, this product will be evaluated as a mobile device per 47 CFR § 1.1310 titled “Radiofrequency radiation exposure limits”, generally referred to as MPE limits. In 47 CFR § 2.1091, paragraph (b) defines a mobile device as “a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 cm is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. ” This product is intended to be installed into a vehicle such that the unit is physically secured at one location. In the installation guide supplied with the product, Client has made the following statement: “IMPORTANT: To meet the FCC’s RF Exposure Guidelines, the antenna should be installed so there is at least 20 cm of separation between the body of the user and nearby persons and the antenna”. Based on the installation of the transceiver and the antenna, the transmitters radiating structure is more than 20 cm from the user. Thus, this product is a “mobile device” as defined in section § 2.1091 paragraph (b). Exposure evaluation PG S 4R 2 Where S: power density P: power input to the antenna G: power gain of the antenna in the direction of interest relative to an isotropic radiator. R: distance to the center of radiation of the antenna. ©2017 A Test Lab Techno Corp. Report Number: 1901FS15 Page 4 of 6
