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 in a 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.

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 of the host product will be obligated to stop operating the
device until the interference have been corrected .

Additional testing, Part 15 Sub part B disclaimer The final
host / module combination need to be evaluated against the FCC Part
15B criteria for unintentional radiators in order to be properly
authorized for operation as a Part 15 digital device.
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. 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
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 are active. In certain conditions it might
be appropriate to use a technology-specific call box (test set) where
accessory 50 devices or drivers are not available. When testing for
emissions from the unintentional radiator, the transmitter shall be
