INSTRUCTIONS FOR LANYARD USAGE

Place the controller in the plastic holder at the end of

The breakaway buckle of the lanyard must be positioned at
the back of your neck (1).

17

TRANSMISSION

With either TV or audio connected

• Press the transmission on/off key on the controller

once to start transmitting from the connected
source. An acoustic signal will sound in your hearing
aids, and the transmission LED will turn green.

• Press the key again once to stop transmission. The

hearing aids will enter the Master program as indi­cated by a voice message or beep tones. The green
LED will change briefly to red and then off.

With both TV and audio connected:

• Press the transmission on/off key on the controller

once to start transmission from the TV. An acoustic
signal will sound in your hearing aids, and the trans­mission LED will turn green.

• Press the key a second time to transmit sound from

the audio source instead. An acoustic signal will
sound in your hearing aids.

• Press the key a third time to stop transmission. The

hearing aids will enter the Master program, as indi­cated by a voice message or beep tones. The green
LED will change briefly to red and then off.

18

If you carry your controller around with you and move
outside the operating range, transmission will be in­terrupted and your hearing aids will switch to the Mas­ter program. The LED will flash at slow intervals to in­dicate that transmission has been interrupted. The
change will be indicated by a voice message. If your
hearing aids are set up with beep-tone indication in­stead, no acoustic indication will sound.

If you come in range again, the controller will detect
the signal from the TV/Audio and restart transmission.
A sound will be heard in the hearing aids. The LED will
light constantly rather than flash.

Note that the LED may continue to be red if you chose
to turn off the hearing aid microphones during trans­mission.

19

Adjusting the volume

Press the volume up key to raise the volume of the
transmitted TV or audio sound. Press the volume
down key to lower the volume.

UP

DOWN

Mute

You can mute the transmitted TV or audio sound on
the TV or audio source.

Room off

If you wish to turn the hearing aid mi­crophones off during transmission, so
that you only hear the transmitted

sound, press the room on/off key once.
To turn the microphones back on, press again. An
acoustic indicator will sound in your hearing aids, and
the red LED will turn off.

20

Recharging the battery

The controller uses a rechargeable battery. When fully
charged, the battery has a capacity of approx. 10
hours of transmission, decreasing over time. When
the battery runs low, transmission is interrupted. To
recharge the battery, place the controller in the base
for approximately 4 hours.

You can also recharge the battery using an appropri­ate USB power supply supplied by Widex.

WARNING

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

21

CARING FOR YOUR TV-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 device:

WARNING

• Do not expose the device to extreme temperatures or high
humidity.

• Do not immerse it in water or other liquids.

CAUTION

• Clean the device with a soft cloth. Never clean it with acids,
alcohol, strong detergents or other liquids.

• Avoid dropping the device

• It is not recommended to keep your mobile phone/PDA
within close proximity of the device e.g. same pocket.

• Never try to open or repair the device yourself.
(To be performed by authorized personnel only).

22

WARNING

• Do not carry your device with you during X-rays, MRIs and

other scans or radiation treatments and never place your

device in a microwave oven. These are some of the types of
radiation that can damage your device.

• Radiation from room surveillance equipment, burglar

alarms, mobile phones and similar sources is weaker and
will not damage your device. However, on occasion radia­tion from devices such as certain burglar alarms, automatic
motion detectors and other electronics may cause noticea­ble audible interference during device and hearing aid use.

23

WARNINGS

WARNING

• Keep the TV-DEX and its parts and accessories out of reach
of children and anyone else who might swallow parts of the
device, 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 per­mission.

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

24

CAUTION

• Although your 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 devices.

25

WARNING

Interference with active Implants

• In order to show caution, we advise to follow the guidelines
recommended by manufacturers of defibrillators and pace­makers regarding use of mobile phones:

• If you wear an active implantable device keep the Wireless
Hearing Aids and Hearing Aid Accessories such as wireless
devices or communicators at least 15 cm 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 implant. 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 away from the implant. (*= can be specified
as Autophone magnet, hearing instrument case, magnet in a
tool, etc.)

26

SAFETY WARNING

This device is powered by an external power supply.

• Only connect a power supply that is compatible
with the TV-DEX.

• The power supply must have an output rating of
5VDC, 500mA and mini USB connector.

• The power supply input rating voltage must match
the mains power voltage in your region and the
power supply must have a mains male plug that is
compatible with the AC wall socket 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 that is delivered by your Widex Distrib­utor to ensure safe and efficient use of your TV-DEX.
