Information on test modes and additional testing requirements
a) The modular transmitter has been fully tested by the module grantee on the required number of channels,
modulation types, and modes, it should not be necessary for the host installer to re-test all the available
transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular
transmitter,perform some investigative measurements to confirm that the resulting composite system does
not exceed the spurious emissions limits or band edge limits (e.g., where a different antenna may be causing
additional emissions).
b) The testing should check for emissions that may occur due to the intermixing of emissions with the other
transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation
is especially important when integrating multiple modular transmitters where the certification is based on
testing each of them ina stand-alone configuration. It is important to note that host product manufacturers
should not assume that because the modular transmitter is certified that they do not have any responsibility
for final product compliance.
c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate
the issue. Host products using a modular transmitter are subject to all the applicable individual technical
rules as well as to the general conditions of
operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator ofthe host product will be
obligated to stop operating the device until the interference hasbeen corrected
2.10 Additional testing, Part 15 sub part B disclaimer
The final host / module combination need to be evaluated against the FCC Part 15Bcriteria for unintentional
radiators in order to be properly authorized for operation as a Part15 digital device.
Below are steps for TX verification：

Other in User Manual
The host integrator installing this module into their product must ensure that the final composite product
complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the
transmitter operation and should refer to guidance in KDB 996369.
Frequency spectrum to be investigated
For host products with certified modular transmitter, the frequency range of investigation of the composite
system is specified by rule in Sections 15.33(a)(1) through (a)(3), or the range applicable to the digital device,
as shown in Section 15.33(b)(1), whichever is the higher frequency range of investigation.
Operating the host product
When testing the host product, all the transmitters must be operating. The transmitters can be enabled by
using publicly-available drivers and turned on, so the transmitters a reactive. In certain conditions it might be
appropriate to use a technology-specific call box(test set) where accessory devices or drivers are not
available.When testing for emissions from the unintentional radiator, the transmitter shall be placed in the
receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be passive
(preferred) and/or active scanning. In these cases, this would needto enable activity on the communication
BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled. Testing laboratories may
need to add attenuation or filters depending on the signal strength of any active beacons (if applicable)from
the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further general testing details.
