Applicant ShangHai Ehong Technology Co.,Ltd. FCC ID: 2ACCRES201 Section 15.212 Modular Transmitters Request for Modular Approval Request for Limited Modular Approval  RequirementsEUT ConditionsComply(Y/N) Single Modular Approval Requirements 1 The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. Refer to external photos. This module have shield cover. Y 2 The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over‐modulation. All inputs to the modules are buffered through logic or microprocessor inputs. Refer to Schematics. Y 3 The modular transmitter must have its own power supply regulation. The Module uses the chip nRF52810 with built-in power management components, the module rated power is 1.7-3.6V power, Refer to schematics. Y 4 The modular transmitter must comply with the antenna and transmission system requirements of §§15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of §15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. The modular transmitter has a PCB antenna and an Omni antenna arrangement for BLE, Refer to EUT photos. Y Company: ShangHai Ehong Technology Co.,Ltd. Add: Suite501,No.3 building,No.439 Jinglian road,Minhang district,Shanghai,China Tel: 021-61263536 Fax: 021-61263536 E-mail: [email protected] 5 The modular transmitter must be tested in a stand‐alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in §15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see §15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see §15.31(i)). The modular transmitter is connected to the controlled board when testing. Please refer to setup photo. Y 6 If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:“ContainsTransmitter Module FCC ID: 2ACCRES201”Any similarwording that e xpresses the same meaning may be used. The Grantee may either provide such a label, a n example of which must be included Refer to the label. Y in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. 7 The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. Refer to manual Y 8 The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. The EUT comply with any applicable RF exposure requirements Y Sincerely, Signature: Typed or Printed Name:Tony Tang Title: General Manager

Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHF200114005-00A FCC Part 15.247 Page 12 of 53 FCC§15.247 (I), §1.1310 &§2.1093 –RF EXPOSURE Applicable Standard According to§2.1093and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 General RF Exposure Guidance The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/ (min. test separation distance, mm)] · [√f (GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where 1. f (GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Measurement Result Mode Frequency Range (MHz) Max Tune-up Conducted Power Calculated Distance (mm) Calculated Value Threshold (1-g SAR) SAR Test Exclusion (dBm) (mW) BLE (1Mbps) 2402-2480 3.50 2.24 5 0.7 3.0 Yes BLE (2Mbps) 2402-2480 3.50 2.24 5 0.7 3.0 Yes Result: No SAR test is required.
