Long-Term Confidentiality for Internal Photographs

Question: We manufacture a handheld medical device for which we will be seeking FCC certification; it is used in conjunction with an implantable medical device. We feel it is critically important to permanently withhold from public view the internal photographs of the handheld device. Our research on this topic indicates that the FCC is likely to approve such a request if the internal components and printed circuit board are enclosed in epoxy, however this is not the case with our handheld device. How do we proceed?

Answer: Under special conditions, the FCC will consider granting long-term confidentiality to the internal photograph exhibit which will include the printed circuit board and components. The certification application cover letter requesting long-term confidentiality for the internal photograph exhibit must include the following justification, which should be as specific and detailed as possible:

  1. A sample of the Non-Disclosure Agreement (NDA) that the grantee will enter into with every purchaser, professional designated technician, third-party sales, and end user of the device.
  2. A statement that all sales of the device will be subject to the NDA, including third party sales, as well as the final user of the device.
  3. A detailed description as to how the internal photographs are controlled to prevent disclosure to unauthorized persons or to the public.
  4. A description of the restrictions in place to prevent public access to products serviceable by professional designated technicians.
  5. The key terms and stipulations of the NDA, to indicate consistency between the long-term confidentiality request letter and the NDA itself.

This and other information concerning both long-term confidentiality and short-term confidentiality can be found here.


Ultrasonic Device Compliance

Question: We design a 30 kHz ultrasonic device that is used to clean nuclear rods. Is this device subject to FCC regulations?

Answer: Because your device uses radio frequency to generate the ultrasonic waves, it is indeed subject to FCC regulations, including authorization via certification or SDoC as appropriate. addresses Industrial, Scientific and Medical equipment. Specifically, you should review for the field strength limits, for the conducted limits, and for notes on the measurement methods.


Rack-Mounted Licensed Transmitter Certification

Question: Is it possible to certify under one FCC ID a rack-mounted licensed transmitter system with multiple amplifiers marketed with one or more external amplifier modules?

Answer: Rack-mounted licensed transmitters with multiple amplifiers marketed with one or more amplifier modules can be approved under one FCC ID only under the following conditions:

  1. The amplifier modules are identical in design.
  2. The addition or deletion of amplifier modules changes only the output power. Each output power version must be indicated by a separate equipment specifications line item on the FCC grant. For example, each combination (e.g. 1, 2, or 3 identical "stacked" power amplifiers) must have 3 line items.
  3. The frequency range of different models with different modules must be identical. There can be no differences in the frequency operational range or determining circuitry between the different models with different installed amplifier modules.
  4. Certification applications must include test results with the maximum number of amplifier modules installed. Though only the full rack configuration must be tested and the resulting test data submitted, the Grantee is responsible for ensuring compliance of all configurations to the FCC rules and regulations.

Please note the following:

  • 47CFR§2.1043, Changes in certificated equipment, does not allow a change in the maximum output power so it is not permissible to increase output power beyond that in the original application, nor does it allow a change in frequency determining or output power circuitry, so it is not permissible to add non-identical plug-in modules other than the original module via a Class 2 Permissive Change.
  • Unlicensed Part 15 transmitters must follow the Part 15 amplifier requirements in 47CFR§15.204.

Modifying Modular Approved Transmitters

Question: We obtained modular approval for our transmitter that has voltage regulator circuitry. We would now like to permanently move the voltage regulator circuitry to the host device. Only we will install the transmitter module into the host device. What if any impact will these changes have on the existing modular approval certification?

Answer: The scenario you propose is not allowed by the FCC. It is not permissible to change a modular approval to a limited modular approval, nor is it permissible to change the circuitry of an existing certification. In order to be in compliance with the FCC rules and regulations, the only solution is to apply for a new limited modular approval certification under a new FCC ID for the transmitter without the voltage regulator circuitry, with the condition that only you, the grantee, be able to install the module on the host device with the approved regulator circuitry, following appropriate testing of the host device of course.
