Page 3: Introduction
Introduction At Widex, our overall mission is to give people with a hearing loss the same opportunities for communication as people with normal hearing. A Widex hearing aid, combined with the MicroLink, goes a long way towards achieving this goal by ensuring optimal listening comfort and speech understanding. - Page 4 The MicroLink system is based on technology that makes it possible to manufacture an FM radio receiver so tiny that it can be connected to a hear- ing aid. The receiver’s power consumption is very low, so it can be powered by the hearing aid’s own battery.
- Page 5 If used and cared for properly, your MicroLink system – used in combination with your Widex hearing aid – will give you many pleasurable lis- tening opportunities. The MicroLink system is a precision instrument that can be damaged if knocked or bumped. Therefore it should be hand- led with care and we recommend that you keep it in the leather case when you do not use it.

Page 6: The Fm System And How It Works
The FM system and how it works An FM system is a radio system in which signals are sent via radio waves from the transmitter to the receiver. “FM” stands for Frequency Modula- tion, a technical term for the way radio signals are generated. - Page 7 The MicroLink FM system from Widex is avail- able in two versions – with a HandyMic transmit- ter or with a MicroVox transmitter. Both versions use the MicroLink receiver. Transmission power is very low and involves no physiological side effects. The maximum operating range is about 15...

Page 14: The Handymic Transmitter
The HandyMic transmitter How the HandyMic works The HandyMic is a low power radio transmitter with a built-in multidirectional microphone sys- tem. The transmitter sends signals from the microphone to the MicroLink receiver. Please note that the transmitter and the receiver must be on the same channel/frequency. - Page 15 The integrated multidirectional microphone can be adjusted to pick up signals in three different modes: 1. The omnidirectional microphone picks up sound signals from all directions. 2. The directional microphone primarily picks up sound signals from an angle of 45° in front of the microphone.
- Page 16 The HandyMic can also be connected directly to the headphone outlet of your radio or TV by means of the accompanying audio cord. The trans- mitter is automatically switched on even when it is in the off position when there are incoming audio signals.

Page 44: Getting Started
Getting Started Using the HandyMic may at first require an extra effort because in doing so, you are showing every- one that you have a hearing loss. Try to ignore this. Explain your situation. It may be a good idea to practise on your family or friends. - Page 45 The range of the MicroLink system depends pri- marily on the circumstances for radio wave propa- gation (building construction, metal walls, doorways etc.). The operating range is greatest in open country and least inside steel buildings. Sig- nal fall-out with increased noise may occur in the vicinity of the maximum range.
