Oticon Radio Model - Quick Installation Guide Radio Model Name: Aurora mini RITE-T PEOPLE FIRST The Aurora mini RITE-T radio model contains two radio transceivers running at 3.84 MHz and 2.4 GHz and both implemented on a single hardware platform. Aurora mini RITE-T Radio Model 3D overview The radio model is implemented on the main PCB is shown to the left in 3D with connections to the antennas, the microphones, the speaker and the battery terminals. 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 modes with higher data rates and connected to a short wire antenna.

Aurora mini RITE-T 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 Aurora mini RITE-T radio model requires only a single cell 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.

Aurora mini RITE-T 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 mini RITE 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 mini RITE radio model. The Aurora mini RITE-T radio model is intended to be installed in Oticon, Bernafon, Sonic and affiliated wireless hearing aid devices of the mini RITE-T
