FCC ID: 2AF4S-MV2853BTB MODULAR APPROVAL LETTER Modular Approval Requirement Answers

(i) 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.

(ii) 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.

(iii) The modular transmitter must have its own power supply regulation.

(iv) 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.

(v) The module must demonstrate compliance in a stand-alone configuration.

(vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number.

(vii) 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.

(viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Yes Yes Yes Yes Yes Yes Yes Yes Sincerely, Name: SangSoo Kim Position: Senior Research Engineer
