Radio Model - Quick Installation Guide
Radio Model Name:
MI_AU5_MNR_T
SBO Hearing A/S
, Kongebakken 9, 2765 Smorum - DK-Denmark,
VAT-no.: DK39818558,
3
The most important part of the radio model is the Engine Module (IC1) 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 and coil antenna for the 3.84
MHz radio (L2).
The Aurora5 miniRITE 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.
On the bottom side of the main PCB of the Aurora5 miniRITE T 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 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 Aurora5 miniRITE T 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 Aurora5 miniRITE T radio model.
The Aurora5 miniRITE T radio model is intended to be installed in Oticon, Bernafon, Sonic, Philips and affiliated private labels wireless hearing aid
devices of the miniRITE T (Receiver-In-The-Ear) wearing style.
