MODULAR APPROVAL LETTER 2021-05-07 Applicant : BNCOM CO.LTD FCC ID : 2APDI-BCM-LN200-AS We would like to answer for Single Modular Approval in accordance with the requirement of rule part 15.212 as described below No. Requirements Comment Comply (Y/N) 1 The radio element of the modular transmitter has its own shielding Refer to the external photo Y 2 The modular transmitter must have buffered modulation data/inputs (if such inputs are provided) All input to the modules are buffered through microprocessor inputs. Y 3 The modular transmitter must have its own power supply regulation. Internal power regulators Refer to the Block-diagram Y 4 The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). Refer to the internal photo Y 5 The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. Refer to the test setup photo Y 6 The modular transmitter must be labeled with its own FCC ID. If the FCC ID 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 Refer to the packaging Y 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 Refer to the user manual Y 8 The modular transmitter must comply with any applicable RF exposure requirements Refer to the RF exposure statement for more details.
