Pursuant to 47 CFR 0.457(d) of the FCC Rules, information that is considered trade secret and not routinely available to the public may also be withheld from public inspection if a request for non-disclosure is submitted pursuant to 47 CFR 0.459. This confidentiality request applies to the schematics, block diagrams, theory of operation, manual, and internal photos contained in the following exhibits: Exhibit Type File Name Justification Schematic 11-0215 – Schematics.pdf Proprietary Information and Trade Secret System Block Diagram 11-0215 – System Block Diagram.pdf Proprietary Information and Trade Secret Theory Of Operation 11-0215 – Theory of Operation.pdf Proprietary Information and Trade Secret Manual 11-0215 – Manual.pdf Proprietary Information and Trade Secret Internal Photos 11-0215 – Internal Photos.pdf Proprietary Information and Trade Secret Confidentiality of the Internal Photos is being requested because this is a non-consumer device which is not accessible by the general public and is only serviceable by the applicant or designated technicians. The Manual is technical and is not provided to the consumer because the consumer cannot service or install the device. Therefore confidentiality of the Manual is also requested. The above materials contain trade secrets and proprietary information not customarily released to the public. The public disclosure of these materials may be harmful to the applicant and provide unjustified benefits to its competitors. The product covered by this Confidentiality Request is not sold to any OEM and is only installed in Sensus Products by Sensus Employees or Contractors. The applicant understands that pursuant to Section 0.457 of the Rules, disclosure of this application and all accompanying documentation will not be made before the date of the Grant for this application.

Grant Notes

Modular Approval. Power listed is conducted. Device must operate with a source-based, time-averaged duty cycle not to exceed 12.8%, controlled by firmware or software. This modular approval is limited to products operating as mobile or fixed transmitting device. The antenna(s) used for this transmitter must not be collocated or operating in conjunction with any other antenna or transmitter, except FCC ID: SDBIDTB002 as evaluated in this filing. End-users must be provided with transmitter operation conditions for satisfying RF exposure compliance. Separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations.
