Step : Connecting to the TV
Supported audio formats:
The uTV  can be connected to any audio source
such as a TV, PC or hi- system. It supports
three dierent audio input formats.
For best results, we recommend you use the
optical or coaxial connection if available on your
audio device.
Note: please ensure to always connect uTV  to
the audio output of your device.
Signal priorities:
Normally it is enough to connect one audio
cable. If more than one cable is connected and
a signal is present, uTV  will select the best
possible input in the following order: optical,
coaxial, analog.
Note: even though the optical and coaxial
cables are only one wire, the signal is stereo.
uTV  shows the selected input by an orange
audio indicator light:

When using your streamer for the rst time,
charge it for at least three hours even if the
battery indicator turns green earlier. Aer the
initial charge, you may leave the streamer in the
charging slot for and unlimited time.
Charging is complete when the streamer’s
indicator light turns solid green.
The uTV  can either be on or o during
charging. Its status indicator light does not
indicate the charging process.
The typical time to fully charge the streamer is
 minutes.
We recommend that the streamer is switched
o while charging.
For safety reasons, recharge the battery
only with chargers supplied by Unitron. If
other chargers are used they must be USB
certied (. VDC/ mA).
Step : Pairing uTV  with your streamer
If you have received the uTV  and the Unitron
streamer together in a complete set, they are
paired already and you may move on to Step 7. If
they were purchased separately, they must rst
be paired with each other.
First, put your streamer into pairing mode.
(Check your streamer’s user guide for further
details.)
Next, put the uTV  into pairing mode.

uTV  will remain in pairing mode for two
minutes or until the pairing has been
completed.
Completion of pairing
Wait until both indicator lights turn solid blue.
This can take up to two minutes but usually
occurs within a few seconds.
The uTV  basestation can be paired to a
maximum of four streaming devices. A h
pairing will replace the rst paired device.
The two devices only need to be paired once.
They remain paired aer switching o and will
automatically connect aer being switched on
again.
Daily usage of the uTV 
Step : Wearing your streamer
Wear the streamer as shown and switch it on.
For a more detailed description of the
streamers, refer to the streamer’s user guide.
Aer switching your streamer on, it will
automatically recognize your Unitron wireless
hearing aids.

Step : Listening to the TV
You will hear the sound of the TV directly in your
hearing aids.
If you cannot hear the sound of your TV through
uTV , repeat the setup in steps 1-6.
If no audio is available, uTV 3 automatically
stops the Bluetoogh audio transmission to the
streamer aer ve minutes. Its main indicator
light will blink green.
The uTV  supports Bluetooth operation up to
a range of m (). Line-of-sight between
your streamer and the uTV  is not required.
However, interference in the environment by
walls or furniture may reduce the operating
range.
If the streamer moves out of range of the
uTV, the wireless audio transmission will be
terminated. If the streamer is then moved back
into range of the uTV , it will automatically
resume streaming to your hearing aids.
It may take up to ten seconds until the
streaming resumes. Both streaming light
indicators, should be solid blue during
streaming.
If the uTV  status light:
• blinks green, make sure the audio input to
the uTV  is properly connected.
