User's Manual

Label and compliance information When the module is installed in the host device, the
FCC ID label must be visible through a window on the final device or it must be visible when
an access panel, door or cover is easily re‐moved. If not, a second label must be placed on
the outside of the final device that contains the following text: Contains Transmitter Module
FCC ID:
2AD56HLK-B32
, the FCC ID can be used only when all FCC ID compliance
requirements are met.
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 in
a stand‐al one confi gurati on. I t i s i m portant to note that host product m anuf acturers
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 of
the host product will be obligated to stop operating the device until the interference has
been corrected.
Addi
tional testing, Part 15 Subpart 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 Part15 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 devices or drivers
are not available. When testing for emissions from the unintentional radiator, the transmitter
