PART 15 Request LIMITED Modular Approval

1. RF Shielding

The modular transmitter must possess its own RF shielding. This ensures that the module does not rely on the shielding of the device it is installed in for compliance with Part 15 limits. It also prevents coupling between the module's RF circuitry and other circuits in the host device, which could lead to non-compliant operation.

Answer: The transmitter has its own shielding.

2. Buffered Modulation/Data Inputs

The modular transmitter must have buffered modulation/data inputs to ensure compliance with Part 15 requirements under conditions of excessive data rates or over-modulation.

Answer: Buffered data inputs are integrated in IC BCD100

3. Power Supply Regulation

The modular transmitter must have its own power supply regulation to ensure compliance with Part 15 requirements, irrespective of the power supplying circuitry in the host device.

Answer: The transmitter module is host powered but has its own power supply regulation.

4. Antenna Requirements

The modular transmitter must comply with antenna requirements of Section 15.203 and 15.204(c). The antenna must be permanently attached or use a "unique" antenna coupler for all connections between the module and the antenna. Any antenna used must be approved with the module. The "professional installation" provision of Section 15.203 does not apply to modules.

Answer: The modular approved transmitter is equipped with an external antenna connector of MMCX-type. This connector is not commonly available to end users.

5. Stand-alone Testing and Conducted Emissions

The modular transmitter must be tested in a stand-alone configuration to demonstrate compliance with Part 15 emission limits, regardless of the host device. Unless battery-powered, it must comply with AC line conducted requirements (Section 15.207). Power lines and data input/output lines connected to the module should not contain ferrites unless marketed with the module. Line lengths should be typical for actual use or at least 10 centimeters to prevent coupling. Accessories and support equipment used during testing must be unmodified or commercially available.

Answer: The RF module is tested in stand-alone configuration as documented in the test report and on the test setup photos.

6. Labeling Requirements

The modular transmitter must be labeled with its own FCC ID. If the FCC ID is not visible when installed in another device, the exterior of the host device must display a label referring to the enclosed module, such as "Contains Transmitter Module FCC ID: XYZMODEL1" or "Contains FCC ID: XYZMODEL1." Adequate instructions explaining this requirement must be provided with the module.

Answer: The modular approved transmitter is labeled with its own FCC ID. The final host product, into which this modular approved transmitter is finally integrated, will be labeled with an auxiliary label, such as: See user manual

7. Rule and Operating Requirement Compliance

The modular transmitter must comply with specific rules and operating requirements. Manufacturers must provide adequate instructions explaining these requirements, including strict operational and timing requirements for Section 15.231, and any restrictions on data transmission.

Answer: The EUT is compliant with all applicable FCC rules.

8. RF Exposure Requirements

The modular transmitter must comply with applicable RF exposure requirements, including those in FCC Rules Sections 2.1091, 2.1093, 15.319(i), 15.407(f), 15.253(f), and 15.255(g). Spread spectrum transmitters under Section 15.247 must address RF Exposure compliance per Section 15.247(b)(4). Modular transmitters may need to provide specific installation and operating instructions for compliance.

Answer: The EUT is compliant with all applicable RF exposure requirements. See MPE calculation in report 140234-AU01+W01_RF-Report_TC241.

9. Antenna Requirement Details

The modular approved transmitter features an onboard MMCX-type antenna connector, defined as unique per §15.203. The intended antenna uses a standard SMA connector, connected via a MMCX-to-SMA adaptor cable, which is no longer considered unique. Integration is strictly limited to the Grantee for end products used in an industrial environment or requiring professional installation.

10. RF Exposure for Installations

The modular approved transmitter complies with the RF Exposure requirements for fixed or mobile installations / categorized host devices.
