Oticon Radio Model - Quick Installation Guide
Radio Model Name: ITE 3M84
The ITE 3M84 radio model is a low power, inductive radio transceiver working at 3.84 MHz consisting of:
• a Digital-Signal-Processor (DSP)
• a radio Front-End (FE)
• memory
• antenna coil
• and smaller components
The DSP, FE, memory and smaller components are all mounted on a flexible
Printed-Circuit-Board (PCB), which is connected to the antenna by another long and
thin flex PCB. The FE is a complete radio transceiver, including both transmitter,
receiver and local oscillators. All these components are kept in place by a
mechanical carrier building up the amplifier, which is intended to be installed as a
module into Oticon wireless hearing aid devices only.
The module also has all voltage regulators included inside the DSP and FE and
buffered data programming inputs on the board.
The module requires a battery, one or two microphones and an audio receiver to be
attached and must be mounted in an external plastic shell.
The module is depicted to the right with its main components and connections:
