WARNING
This booklet contains important information and instructions. Please
read this booklet carefully before you start using the device.
M-DEX is an advanced hearing aid remote control. M-DEX repro-
duces mobile phone conversations directly in the hearing aid and
allows the user to control normal mobile phone functions and lis-
ten to audio input, using a Bluetooth connection for compatibility
with most models of mobile phone, and WidexLink for connection
to Widex hearing aids.
INTENDED USE
The M-DEX is a wireless device intended for mobile phone appli-
cations, as well as an advanced remote control.

LANYARD USAGE
If you wish to wear the M-DEX around your neck, place it in the
plastic holder at the end of the lanyard provided, as illustrated.
14

WARNING
The breakaway buckle of the lanyard must be positioned at the back of
your neck (1), to make it easier to unsnap.
15

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.
16

To charge the battery
1. Connect the charger to the M-DEX.
2. Plug the charger into a wall socket.
17

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. Contact your hearing care pro-
fessional.
18

TURNING ON THE M-DEX
Push the slide button on the right side upwards.
19

Note
The icons and screens in your M-DEX will depend on how it has been
configured by the hearing care professional in cooperation 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.
