Requirement per KDB996369 D03
2.2 List of applicable FCC rules
List the FCC rules that are applicable to the modular transmitter. These are the rules that
specifically establish the bands of operation, the power, spurious emissions, and operating
fundamental frequencies. DO NOT list compliance to unintentional-radiator rules (Part 15 Subpart
B) since that is not a condition of a module grant that is extended to a host manufacturer. See also
Section 2.10 below concerning the need to notify host manufacturers that further testing is
required.3
Explanation: This module meets the requirements of FCC part 15C (15.225).it specifically establish the
Radiated Spurious Emission, Frequency Tolerance, Occupied Bandwidth
2.3 Summarize the specific operational use conditions
Describe use conditions that are applicable to the modular transmitter, including for example any
limits on antennas, etc. For example, if point-to-point antennas are used that require reduction in
power or compensation for cable loss, then this information must be in the instructions. If the use
condition limitations extend to professional users, then instructions must state that this information
also extends to the host manufacturer’s instruction manual. In addition, certain information may
also be needed, such as peak gain per frequency band and minimum gain, specifically for master
devices in 5 GHz DFS bands.
Explanation: Antenna is irreplaceable for Part15 radio. The product compliance only with the one
certified antenna.
2.4 Limited module procedures
If a modular transmitter is approved as a “limited module,” then the module manufacturer
isresponsible for approving the host environment that the limited module is used with. The
manufacturer of a limited module must describe, both in the filing and in the installation
instructions, the alternative means that the limited module manufacturer uses to verify that the host
meets the necessary requirements to satisfy the module limiting conditions.
A limited module manufacturer has the flexibility to define its alternative method to address the
conditions that limit the initial approval, such as: shielding, minimum signaling amplitude, buffered
modulation/data inputs, or power supply regulation. The alternative method could include that the
limited module manufacturer reviews detailed test data or host designs prior to giving the host
manufacturer approval.
This limited module procedure is also applicable for RF exposure evaluation when it is necessary
to demonstrate compliance in a specific host. The module manufacturer must state how control of
the product into which the modular transmitter will be installed will be maintained such that full
compliance of the product is always ensured. For additional hosts other than the specific host
originally granted with a limited
module, a Class II permissive change is required on the module grant to register the additional
host as a specific host also approved with the module.
Explanation: The module is a limited module.
2.6 RF exposure considerations
It is essential for module grantees to clearly and explicitly state the RF exposure conditions that
permit a host product manufacturer to use the module. Two types of instructions are required for
RF exposure information: (1) to the host product manufacturer, to define the application conditions
(mobile, portable – xx cm from a person’s body); and (2) additional text needed for the host
product manufacturer to provide to end users in their end-product manuals. If RF exposure
