1        The radio elements of the modular Refer to external photos.   Y
            transmitter must have their own shielding.   This module       does        have
            The physical crystal and tuning capacitors   shield cover.
            may be located external to the shielded
            radio elements.



2           The modular transmitter must have            All inputs to the modules            Y
            buffered modulation/data inputs (if such     are buffered through logic
            inputs are provided) to ensure that the      or microprocessor inputs.
            module will comply with part 15              Refer to Schematics.
            requirements under conditions of
            excessive data rates or over‐modulation.

3           The modular transmitter must have                                                 Y
                                                         RTL8710BX with built-in power
            its own power supply regulation.             management components, the
                                                         module reted power is 3.3V
                                                         power, Refer to schematics.

4           The modular transmitter must comply          The modular                          Y
            with the antenna and transmission system     transmitter has a PCB
            requirements of §§15.203, 15.204(b) and      antenna arrangement for
            15.204(c). The antenna must either be        Wi-Fi, Refer to internal
            permanently attached or employ a             photo.
            “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.


5   The modular transmitter must be            The modular transmitter   Y
    tested in a stand‐alone configuration,     is connected to the
    i.e., the module must not be inside        controlled board when
    another device during testing for          testing.
    compliance        with      part      15   Please refer to setup
    requirements. Unless the transmitter       photo.
    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)).

6   If using a permanently affixed label, Refer to the label.            Y
    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: 2ANDL-WR2L”Any
    similarwording that expresses the
    same meaning may be used. The
    Grantee may either provide such a
    label, an example of which must be
    included


             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            Refer to manual               Y
             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.
8            The modular transmitter must            The EUT comply with           Y
             comply with any applicable RF           any applicable RF
             exposure requirements in its final      exposure requirements
             configuration.                          in its final configuration.
