4. The module shall be in non-detachable construction protection into the finished products, so that the end-user has to destroy
the module while remove or install it.
5. This module is to be installed only in mobile or fixed applications. According to FCC part 2.1091(b) definition of mobile and
fixed devices is:.
Mobile device:
A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in
such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating
structure(s) and the body of the user or nearby persons. In this context, the term ‘‘fixed location’’ means that the device is
physically secured at one location and is not able to be easily moved to another location.
Portable device:
For purposes of this section, a portable device is defined as a transmitting device designed to be used so that the radiating
structure(s) of the device is/are within 20 centimeters of the body of the user.
6. Separate approval is required for all other operating configurations, including portable configurations with respect to FCC
Part 2.1093 and different antenna configurations.
7. A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label,
the module must be labelled with an FCC ID: ORP-IBT-07. The OEM manual must provide clear instructions explaining to
the OEM the labelling requirements, options and OEM user manual instructions that are required
For a host using a this FCC certified modular with a standard fixed label, if (1) the module’s FCC ID is not visible when installed
in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to
remove the module so that the FCC ID of the module is visible; then an additional permanent label referring to the enclosed
module: “Contains Transmitter Module FCC ID: ORP-IBT-07” or “Contains FCC ID: ORP-IBT-07” must be used. The host OEM
user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID.
8. Host product is required to comply with all applicable FCC equipment authorizations regulations, requirements and
equipment functions not associated with the transmitter module portion, compliance must be demonstrated to regulations for
other transmitter components within the host product; to requirements for unintentional radiators (Part 15B). To ensure
compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s)
installed and fully operational. If a host was previously authorized as an unintentional radiator under the Declaration of
Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for
ensuring that after the module is installed and operational the host continues to be compliant with the Part 15B unintentional
radiator requirements. Since this may depend on the details of how the module is integrated with the host, we suggest the
host device to recertify part 15B to ensure complete compliance with FCC requirement: Part 2 Subpart J Equipment
Authorization Procedures , KDB784748 D01 v07, and KDB 997198 about importation of radio frequency devices into the
United States.
