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 WidexLink technology; i.e. signals are
received, altered and transmitted to the hearing aid.

4

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 computer 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 professional.

GETTING STARTED

Charging the battery

The device uses a rechargeable battery that is charged
through the mini USB connector. When fully charged,
the battery has a capacity of approx. 10 hours of con­tinuous use. The charger is available in four country
versions. The version you have may therefore not look
exactly as illustrated in this booklet.

1. Connect the charger to the mini USB connector at
the bottom of the FM+DEX.

2. Plug the charger into a wall socket.

It takes approximately 4 hours to charge the battery
the first time. Recharging takes approx. 2 hours. The

device cannot stream while recharging.

WARNING
Do not attempt to change the battery. Contact your hearing
care professional.
