YOUR NEW FM+DEX
Your FM+DEX is part of the DEX™ family of assistive listening
devices. These user instructions explain how the FM+DEX should
be operated.
WARNING
This booklet contains important information and instructions. Please
read this booklet care fully before you start using the device.
Intended use
The FM+DEX is a battery-powered device intended to transmit (or
stream) signals to Widex hearing aids using the wireless Widex-
Link technology; i.e. signals are received, altered and transmit-
ted to the hearing aid.
6
9 514 0198 001 #05.indd 6 05-11-2020 14:16:18
Description of device
The FM+DEX is offered in order to support Widex hearing aids
without DAI (direct audio input) or a telecoil.
When the FM module is attached, the user is able to receive FM
signals.
In the same way, the device can substitute for a telecoil in hearing
aids not fitted with a telecoil. The third input possibility is the line
in, which can be used to stream music, etc., by connecting a com-
puter or portable unit to the device.
The FM+DEX is worn on a neck loop antenna or attached directly
to clothing using the included clip.
If you need help to identify the serial number (usually six or seven
digits) on the product, please contact your hearing care profes-
sional.
