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.

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:
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.

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:
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 Oticon, Bernafon, Sonic and affiliated wireless hearing aid devices of the miniRITE T 312
Rc (Receiver-In-The-Ear) wearing style.

Oticon Radio Model - Regulatory Label Information for Japan
Radio Model Name: Aurora miniRITE 312 T Rc
Description: Radio module with 2.4 GHz low power transceiver to be integrated into Oticon, Bernafon, Sonic
hearing instruments and associated devices.
Regulatory label:
This device is granted pursuant to the Japanese Radio Law (電波法) and the Japanese Telecommunications Business
Law (電気通信事業法) under the grant ID n° 認証番号: 202-LSF003 (Example)
This device should not be modified (otherwise the granted designation number will become invalid)
本製品の改造は禁止されています。（適合証明番号などが無効となります。）
NB: The regulatory label is not shown on the radio module itself or any end products with it, since they are too small for
the label to be readable without any optical aids or magnification. Below the radio module is shown, indicating a size of
about 5x10x28 mm.
