WHEN USING MORE THAN ONE TV-BASE

If you only have one base, this base is automatically
selected the first time you charge the controller in
the base. If you have more than one base, you can
change between these by placing the controller in
the base you wish to use for approx. 5 seconds.

usage

We recommend that you hang the controller around
your neck when in use, on the lanyard provided.

14

Place the controller in the plastic holder at the end
of the lanyard as illustrated.

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

TRANSMISSION

With either TV or audio connected

• Press the transmission on/off key on the control-

ler 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 control-

ler 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.

16

UP

DOWN

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 beep­tone 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.

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.

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.

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.

Contact your hearing care professional if the bat­tery needs replacement.

Caring tiPs anD warnings

• The TV-DEX units are valuable objects and should

be treated with care.

• Do not expose your TV-DEX units to extreme

temperatures or high humidity.

• Never try to open or repair the TV-DEX units

yourself. (This should only be done by authorised
personnel.)

• Clean the units with a soft cloth. Never wash them

with water, cleaning solutions or other liquids.

• Do not carry the TV-DEX units with you during X-

rays, scans or radiation treatments and never
place them in a microwave oven. These are some
of the types of radiation that can damage the
units. However, radiation from, for example, room
surveillance equipment, burglar alarms or mobile
phones is weaker and will not damage your TV­DEX units.

• Keep your TV-DEX units and their parts and ac-

cessories out of reach of children and anyone else
who might swallow parts of the devices, or other­wise cause injury to themselves with these items.
In case of ingestion, contact a physician immedi­ately.

• Do not use the TV-DEX units on aeroplanes or in

hospitals without permission.

22

23

• Do not use the TV-DEX units in mines or other ar­eas with explosive gases.

• Although the TV-DEX units have been designed
to comply with the most stringent international
electromagnetic compatibility standards, the
possibility cannot be excluded that they may
cause interference with other equipment, such as
medical devices.

• If you wear your TV-Controller around your neck,
make sure that the breakaway buckle on the lan­yard is always at the back of your neck.

• TV-DEX units are made of modern non-allergenic
materials. Nonetheless, in rare cases skin irrita­tion may occur. If you notice such skin irritation,
contact your hearing care professional.

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 TV­DEX.
