WARNING

Interference with active Implants

• In order to show caution, we advise to follow the guidelines recom-

mended by manufacturers of defibrillators and pacemakers regard-

ing use of cell phones:

• If you wear an active implantable device keep the Wireless Hearing

Aids and Hearing Aid Accessories such as wireless remote controls or

communicators at least 15 cm/6 inches away from the implant.

• If you experience any interference, do not use the hearing aids and/

or hearing aid accessories and contact the manufacturer of the im-

plant. Please note that interference can also be caused by power

lines, electrostatic discharge, airport metal detectors etc.

• If you have an active brain implant, please contact the manufacturer

of the implant for risk evaluation.

If you have an implantable device, we advise to keep magnets* at least

15 cm/6 inches away from the implant. (*= can be specified as Auto-

phone magnet, hearing instrument case, magnet in a tool, etc.)

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 Blue-

tooth 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.

17

To charge the battery

1. Connect the charger to the M-DEX.

2. Plug the charger into a wall socket.

18

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

professional.

19

TURNING ON THE M-DEX

Push the slide button on the right side upwards.
