1 FCC E-Label Information A. Information to be displayed 1. The information that will be displayed on the e-label and information that will remain in the user manual is shown below: Information on E-label In Manual FCC ID number Yes Yes FCC logo Yes Yes 15.19 statement (“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.”) Yes Yes Images of the e-label screen are provided below: 2 B. Access to the required information on the e-label 1. Users must be able to access the regulatory information without requiring special access codes or permissions, and in all cases the information must be accessible in no more than three steps from a product’s main or home menu. The screen is accessible by swiping up on the Main Room menu to get to the Dial Info screen, then tapping the Legal And Regulatory linked label. No special code is required. 2. Instructions must be provided with the product at the time of purchase, in the user manual, operating instructions, packaging material, quick guide pamphlet, etc. Alternatively, a product-related website is permitted, if a reference (URL) to obtain the website information is provided at the time of purchase in the user manual, operating instructions, packaging material, quick guide pamphlet, etc. The information to access the FCC E-Label is provided in the user manual. 3. Products must not require special accessories or supplemental plug-ins (e.g., the installation of a SIM/USIM card) to access the information. Access to regulatory information must be provided without special codes, accessories, or permissions beyond the normal security protection to unlock the screen, sign-in page, or overall product access. The device does not require a special code, accessories or supplemental plug-ins to access the information. 4. The FCC ID, warning statements, or other information must be displayed electronically in a manner that is clearly legible without the aid of magnification. The information is clearly legible without the aid of magnification. 5. Both regulatory information and dedicated exclusive application(s) or script(s) must be secured and implemented in a factory-set- unalterable format. The regulatory information must be capable of being retrieved and displayed locally, and under the control of the end user in possession of the product. The method must be secure, such that the application or script ensures that the regulatory information correctly displayed. The regulatory information is included as part of the production binary. The binary is not alterable after compilation since it is compiled. The binary is loaded on the device at the factory. It is not possible to flash a new binary onto the device without authentication. C. Labeling for Importation and Purchasing 1. When e-labeling is used, a physical temporary label is also required on the product, or a label on the packaging, at the time of importation, marketing, and sales.8 The physical label can be a summary version of the required regulatory information, such that the product can be identified as complying with the FCC’s equipment authorization requirements. The information may simply be the FCC ID for products subject to certification. The FCC logo, FCC ID, and model number are present on the product packaging. 3 Products imported that are already packaged for sale and have a physical temporary label will satisfy this requirement. However, for products imported in bulk and not packaged individually, it is acceptable to use a temporary removable adhesive label on the product, or temporary or permanent labels on the shipping packaging or protective bags. Any removable adhesive label shall be of a type intended to survive normal shipping and handling.

RF Exposure Limit Introduction According to ANSI/IEEE C95.1-1992, the criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio frequency (RF) radiation as specified in §1.1310. The MPE was calculated at 20 cm to show compliance with the power density limit. The following formula was used to calculate the Power Density: 퐒= 퐏퐆 ퟒ훑퐑 ퟐ Where: S = Power Density P = Output Power at Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna TEL : 886-3-327-3456 Page : 6 of 6 FAX : 886-3-328-4978 Issued Date : May. 15, 2024 Form version: 200414 RF EXPOSURE EVALUATION REPORT Report No. : FA432213 4.

Collocated Power Density Calculation 60GHz Power Density / Limit Wireless module FCC ID: XPYMAYAW2D Power Density / Limit Σ(Power Density / Limit) of 60GHz+WLAN 0.0002 0.09 0.0902 Note: 1. The wireless module FCC ID: XPYMAYAW2D is also integrated into this device, the maximum ratio is 0.09 for Sim-Tx analysis. 2. Σ(Power Density / Limit): This is a summation of [(power density for each transmitter/antenna included in the simultaneous transmission)/ (corresponding MPE limit)], for 60GHz + Wireless module. 3. Considering the 60GHz collocation with the wireless transmitter of the EIRP performance listed in the table above, the aggregated (power density /limit) is smaller than 1. Conclusion: According to 47 CFR §2.1091, the RF exposure analysis concludes that the RF Exposure is FCC compliant.
