Operation is subject to the following two conditions: • This device may not cause harmful interference. 10 • This device & its accessories must accept any interference received, including interference that may cause undesired operation. Part15.21 statement Changes or modifications not expressly approved by the manufacturer (or party responsible) for compliance could void the user’s authority to operate the equipment 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 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: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help.

Seers Technology Co., Ltd. Telehealth Gateway FCC ID : QN8-MH100 RF Exposure Report Issue Date : March 16, 2021 RF Exposure 1. Standard Requirement According to §15.247 (i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. 2. Limits : 3. EUT RF Exposure The max. power of channel, including tune-up tolerance is 3.76 dBm in High channel(2.480GHz); 3.76dBm logarithmic terms convert to numeric result is nearly 2.38 mW. According to the formula. Calculate the EIRP test result: [(max.power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] * [√f(GHz)] General RF Exposure = (2.38 mW / 5 mm) x √2.402GHz = 0.74 ... ① SAR requirement: S=3.0 ... ②; ① < ②. So the SAR report is not required.
