Radio Module installation guide The Aurora miniRITE 312 T Rc radio model contains two radio transceivers running at 3.84 MHz and 2.4 GHz and both implemented on a single hardware platform. The radio model is implemented in an engine module mounted on the main PCB with connections to the antennas, the microphones, the speaker and the battery terminals. The radio model can be seen in 3D overview to the left:

The 3.84 MHz radio is a low power, short range, inductive radio transceiver working at a single channel at 3.84 MHz using MSK modulation with 320 kbit/s data rate and connected to a small coil antenna. The 2.4 GHz radio is a Bluetooth Low Energy (BLE) transceiver using GFSK modulation with 1 Mbit/s data rate also capable of proprietary receiver modes with higher data rates and connected to a short wire antenna. Aurora miniRITE T 312 Rc Radio Model 3D overview SBO Hearing A/S, Kongebakken 9, DK-2765 Smoerum, Denmark Below the main flex PCB of the Aurora miniRITE 312 T Rc radio model with the most important electrical and electro-mechanical components can be seen:

Aurora miniRITE 312 T Rc Radio Model Main PCB Top side The most important part of the radio model is the Engine Module mounted on the main flex PCB, which connects it to both the EEPROM memory and all external connections: On the top side these are the microphones, the battery terminals and the push button. The telecoil is also used for wireless battery charging. The Aurora miniRITE 312 T Rc radio model requires only a single cell rechargeable battery and an external speaker (also incl. the wire antenna for the Bluetooth radio part) to be attached and plastic shells, defining the industrial design of a hearing aid end product and holding everything together, in order to be operational. SBO Hearing A/S, Kongebakken 9, DK-2765 Smoerum, Denmark On the bottom side of the main PCB of the Aurora miniRITE 312 T Rc radio model the connector for the speaker unit assembly (where the wire antenna for the Bluetooth radio is an integrated part), the programming connector, EEPROM memory and coil antenna for the 3.84 MHz radio can be seen:

Aurora miniRITE 312 T Rc Radio Model Main PCB Bottom side The most important parts inside the Engine module are a Digital-Signal-Processor (DSP), a radio Front-End (FE) chip for the 3.84 MHz radio part and an RF chip for the Bluetooth radio part all mounted on a small rigid PCB again mounted on the main flex PCB. The Aurora miniRITE 312 T Rc radio model also includes all voltage regulators and buffered data programming inputs on board. The DSP is the main processor controlling the functionality of both radios in the Aurora miniRITE 312 T Rc radio model. The Aurora miniRITE 312 T Rc radio model is intended to be installed in Bernafon and affiliated wireless hearing aid devices of the miniRITE 312 T Rc (Receiver-

In-The-Ear) wearing style. SBO Hearing A/S, Kongebakken 9, DK-2765 Smoerum, Denmark SBO Hearing Radio Model - Regulatory Label Information for USA & Canada Radio Model Name: Aurora miniRITE 312 T Rc Contains:

Class II Permissive Change (C2PC) 2021-04-15 Federal Communication Commission Equipment Authorization Division, Application Processing Branch 7435 Oakland Mills Road Columbia, MD 21048 Certification and Engineering Bureau Industry Canada Spectrum Engineering Branch 3701 Carling Avenue, Building 94 Ottawa, Ontario K2H 8S2 TO WHOM IT MAY CONCERN Pursuant to the applicable paragraphs in ISEDs RSP-100 7 and CFR 47 FCC part 2.1043(b)(2) we hereby declare the following changes under Class II Permissive Change to the product:

Hearing Instrument amplifier module Aurora miniRITE FCC ID: 2ACAHSBMRTRC 11936A-SBMRTRC IC:

Original grant: February 20th -2019 We, SBO Hearing A/S hereby declare the following Class 2 Permissive Change to the amplifier module Aurora miniRITE related to the FCC part 15.247 / RSS-247 DTS radio:

The change of Bluetooth BAW filter and ESD protection diode due to End-of-Life components changes has been performed with a minor PCB layout change handled in correlation with KDB 178919 D01, section III, subclause D + Page 3, Note 5, bullet 2. Only passive components have been changed. The Limited Modular Approval (LMA) still apply after the C2PC product update. No mechanical changes has been applied to the product for this C2PC. The radio module performance is equal to the previously certified module performance. We, SBO Hearing A/S declare that the hearing aid amplifier module changes as documented in the test report will have a similar module performance as established in the FCC/ISED original certification. SBO Hearing A/S, Kongebakken 9, 2765 Smorum - DK-Denmark, CVR-no.: 39818558, www.sbohearing.com If you have any questions, please feel free to contact me at the address shown below.
