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

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.

gettIng starteD

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.

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.

The program in position number 1 (usually Master) is

displayed.

turnIng off the m‑DeX

To turn the M-DEX off

Push the slide button on

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.

MANUAL KEYLOCK

vated by your hearing care professional.

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

function has been activated.

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-

carIng for your m‑DeX

The device is a valuable object and should be treated

with care. Here are some things you can do to prolong

the life of your M-DEX:

WARNING

• Do not expose the device to extreme temperatures or high

humidity.

• Do not immerse in water or other liquids.

• Do not carry your M-DEX with you during X-rays, MRIs or

other scans or radiation treatments and never place it in a

microwave oven. These are some of the types of radiation that

can damage the device. Radiation from room surveillance

equipment, burglar alarms, mobile phones and similar sources

is weaker and will not damage the device. However on occa-

sion radiation from devices such as certain burglar alarms,

automatic motion detectors and other electronics may cause

noticeable audible interference during M-DEX and hearing aid

use.

CAUTION

• Never try to open or repair the device yourself. (This should

only be done by authorised personnel.)

• Clean the device with a soft cloth. Never wash it with water,

cleaning solutions or other liquids.

• Avoid dropping the M-DEX.

• When the device is not in use, keep it in its case in a cool, dry

location out of reach of children and pets.

warnIngs

WARNING

• Keep the M-DEX and its parts and accessories out of reach of

children and anyone else who might swallow parts of the de-

vice, or otherwise cause injury to themselves with these items.

In case of ingestion, contact a physician immediately.

• Do not use the device on aircraft or in hospitals without per-

mission.

• Do not use the device in mines or other areas with explosive

gases.

• If you wear your M-DEX around your neck, make sure that the

breakaway buckle on the lanyard is always at the back of your

neck.

• The device is made of modern non-allergenic materials. None-

theless, in rare cases skin irritation may occur. If you notice

such skin irritation, contact your hearing care professional.

CAUTION

• Although the device has been designed to comply with the

most stringent international electromagnetic compatibility

standards, the possibility cannot be excluded that it may

cause interference with other equipment, such as medical de-

vices.

safety warnIng

This device is powered by an external power supply.

• Only connect a power supply that is compatible with

the M-DEX.

• The power supply must have an output rating of

5VDC, 500mA, and a mini USB connector.

• The power supply input rating voltage must match

the mains power voltage in your region, and the pow-

er supply must have a male mains plug that is com-

patible with the AC wall sockets in your region

• The power supply must be designed for ITE and must

have the certification marks showing certification by

an agency acceptable in your region.

Widex strongly recommends that you always use a

power supply unit that is supplied by your Widex Dis-

tributor to ensure safe and efficient use of your M-DEX.
