Your M-DEX is part of the DEX™ family of assistive lis-

tening devices. These user instructions explain how the

M-DEX should be operated.

WARNING

This booklet contains important information and instructions.

Please read this booklet care fully before you start using the de-

vice.

INTENDED USE

The M-DEX is a wireless device intended for mobile

phone applications, as well as an advanced remote con-

trol.

DESCRIPTION OF DEVICE

M-DEX is an advanced hearing aid remote control.

M-DEX reproduces mobile phone conversations direct-

ly in the hearing aid and allows the user to control nor-

mal mobile phone functions and listen to audio input,

using a Bluetooth connection for compatibility with

most models of mobile phone, and WidexLink for con-

nection to Widex hearing aids.

If you wish to wear the M-DEX around your neck, place

CHARGING THE BATTERY

The M-DEX uses a rechargeable battery. When fully

charged, the battery has a capacity of approx. 5 hours

of continuous use (when on standby, the battery will

last approximately three days. If Bluetooth is turned on,

this period will be considerably reduced). The charger

is available in four country versions. The version you

have may therefore not look exactly as illustrated in this

booklet.

To charge the battery

1. Connect the charger to the M-DEX.

2. Plug the charger into a wall socket.

10 11

It takes approximately 6 hours to charge the battery

the first time. Allow the battery to charge for the full six

hours, even if the “battery full” icon appears.

Recharging takes approx. 3 hours, depending on

whether the device is turned on or off.

WARNING

Do not attempt to change the battery yourself. Contact your

hearing care professional if the battery needs replacement.

tuRnIng on the m‑DeX

Push the slide button on the right side upwards.

Note

The icons and screens in your M-DEX will depend on how it has

been configured by the hearing care professional in coopera-

tion with you. Your dispenser will have matched the M-DEX with

your hearing aids. Once this is done, you will be able to change

programs and adjust the volume in your hearing aids.

12 13

The program in position number 1 (usually Master) is

displayed.

tuRnIng off the m‑DeX

To turn the M-DEX off

the right side of the M-DEX

downward.

STANDBY SCREEN

To save power, the M-DEX screen will automatically

enter standby mode when it has not been used for 10

seconds.

To leave standby mode

Use any key except the on/off button. If the other keys

are locked, you can use the “No” key to leave standby

mode.

basIC funCtIons

–RemoteContRol

From the start screen you can change programs in your

hearing aid, adjust the volume, choose listening focus

and activate/deactivate Room Off.

Except when using the Room Off function, your hearing

aids will produce speech messages or tones when you

change settings, unless the function has been deacti-

vated by your hearing care professional.

If a check mark is displayed, it means that the specific

function has been activated.

CHANGING PROGRAM

The selection of listening programs in your M-DEX de-

pends on how many and which programs you have cho-

sen to have in your hearing aid. The order of the pro-

grams is the same as in your hearing aid.

The M-DEX always starts up in the program which has

been chosen as program number 1 by you and your

hearing care professional (usually the Master program).

16 17

To navigate through the

available programs

Press  or 

Every time you press one of the arrows, an icon repre-

senting the active program is displayed.

ADJUSTING THE VOLUME

To access the volume bars

Press  or 

To increase or decrease

the volume in both

hearing aids

Press  or 

The volume adjustment will apply only to the listening

program that is currently active.

The wider bar in the middle indicates the default set-

ting. The icon displayed reflects the number of volume

adjustment steps chosen by your hearing care profes-

sional in consultation with you.

The binaural volume adjustment closes automatically

after a few seconds. To close it manually, press the No

key.

Changing to another program or turning the M-DEX off

will cancel any volume adjustment.

If you adjust the volume on the hearing aid’s volume

control, this adjustment will not be copied into the

M-DEX.
