8. 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-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 of the host product

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

9. 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 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 need to 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.

The product under test is set into a link/association with a partnering device, as per the

normal intended use of the product. To ease testing, the product under test is set to transmit

at a high duty cycle, such as by sending a file or streaming some media content.

FCC Warning:

Any Changes or modifications not expressly approved by the party responsible for compliance

could void the user's authority to operate the equipment. This device complies with part 15 of the

FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause

harmful interference, and (2) This device must accept any interference received, including

interference that may cause undesired operation
