Getting started
Charging the uMic
The system consists of three main elements:
• uMic
• Unitron hearing aids
• A streamer
The uMic is compatible with three streaming
devices, uDirect 2, uDirect 3 and uStream.
The uMic transmits the speaker’s voice
wirelessly to your hearing aids via the streamer.
The hearing aid microphone level will
automatically be adjusted while the uMic signal
is received. The level of adjustment is set by
your hearing healthcare professional.
Your uMic has a built-in, non-removable
rechargeable battery. When the battery is low,
the indicator light will blink red.

speaker
To charge:
1. Insert the Unitron
power supply
provided with
the uDirect 2 or
uDirect 3 into the
uMic mini-USB
socket.
2. Plug the power supply into a power outlet.
Typical charging time is two hours. Charging is
complete when the indicator light turns solid
green.
When charging your uMic for the first time, let
it charge for at least three hours, even if the
battery indicator is not lit or turns green earlier.

Off
If after 30 minutes no streamer device is found
the uMic will power down to save battery life
even if the power switch is in the on position.
To recover from sleep mode, switch the uMic off
and turn it on again.
It is safe to leave the uMic connected to the
charger overnight.

Bluetooth pairing with the uMic
Put uMic into pairing mode:
If the uMic has never been paired before,
pairing mode will be automatically activated
after turning it on.
To manually start pairing mode:
1. Switch the uMic off.
2. Press and hold the volume up
button ( ).
3. Turn the uMic on while still
pushing the ( ) button.
4. Release the ( ) button after
two seconds when the indicator
light rapidly blinks blue.
5. Make sure the streamer and uMic are within
1 m (3 ft) range of each other.
The uMic will remain in pairing mode for two
minutes or until the pairing is completed.
8
Completion of pairing:
Wait until both indicator lights turn solid blue.
This can take up to two minutes but typically is
done within a few seconds.
The uMic can be paired to a maximum of four
devices. A fifth pairing will replace the first paired
device.
Two devices need to be paired only once.
They remain paired after switching off and will
automatically connect after being turned on again.

Functional test of uMic
Wearing the uMic correctly
After pairing to your streamer,
perform a quick functional
test by gently tapping on the
microphone opening.
You should clearly hear the
tapping noise in your hearing aids.
1. Gently press to open the clip.
2. Ensure the uMic is clipped
securely to clothing as shown in
the picture.
3. To prevent scratching sounds,
do not cover the uMic with
clothing during use.
Distance to the speaker’s
mouth:
• Best results are achieved
at 20 cm (8’’)
• Do not exceed 50 cm (20’’)
for consistent audio
Line of sight between the uMic and the
streamer is usually not required. If the audio
transmission ends abruptly, refer to the
troubleshooting guide.
The higher the ambient noise, the closer the
uMic should be positioned to the speaker’s
mouth.
Do not use a neckloop lanyard during
streaming. Scratching noise may negatively
impact the sound.
12
13
Setting the uMic volume
Switching the uMic off
To change the uMic volume:
To end the uMic transmission
completely, switch off the uMic by
sliding the power switch to the off
position.
1.Speak into the uMic from a 20 cm
(8”) distance.
2.Use the volume (
) buttons to
set the uMic volume to adjust the
sensitivity and strength of the microphones.
If your hearing aids pick up too much ambient
noise, reduce the volume on your hearing aids
and increase the volume on your uMic.
The uMic volume setting will be stored even
when switched off.
In the off position, the white marking cannot be
seen.
Switch the uMic off when not in use.
If the uMic connection to a streamer was lost
for more than 30 minutes, the uMic will go into
sleep mode to save power. The light indicator
will turn off and a uMic re-start (turn off and on
again) is required to resume the transmission.
Your hearing healthcare professional
can change the level of the hearing aid
microphones while using the uMic to adjust the
volume of sounds around you.
14
15
uMic and phone calls
uMic and watching TV
Phone calls via Bluetooth will always take
priority over the uMic streaming.
If uDirect 2, uDirect 3 or uStream streamer is
paired with your mobile phone, you can still
receive phone calls, even when using uMic.
In case of an incoming call, the streamer
automatically stops transmitting the audio
signal from your uMic and and sends the signal
from your mobile phone to your hearing aids
instead.
To ensure a high quality audio
in stereo sound from the TV,
we recommend using the
dedicated uTV 3.
In cases where an analog TVaudio output is not available uTV 3
or while traveling, the uMic
may be used to improve the
sound quality while watching TV.
For best results:
1. Try to locate the TV
loudspeaker.
2. Place the uMic 20 cm (8’’)
from the speaker.

3. Consider leaving the
charger plugged in while
watching TV.

uMic streaming distance
Deleting all Bluetooth pairings
The uMic transmitter supports operation up to
a range of 20 m (65 ft). Line-of-sight between
your streamer and the uMic is not required.
Interference in the environment by objects
in the line-of-sight may reduce the operating
range.
If the uMic is moved out of range of the
streamer, the wireless audio transmission will
be interrupted or even terminated. If the uMic
is then moved back into range of the streamer,
it will automatically resume streaming to your
hearing aids.
It may take up to ten seconds until the
streaming resumes.
If you encounter issues with one of the paired
devices, or if a device stops connecting to your
uMic, you may consider deleting all pairings
from the uMic.
1. Turn the uMic on while pushing
and holding the ( ) button for
ten seconds. This deletes all
pairings.
2. R
elease the ( ) button when the
blue indicator light turns green.
Deleting the pairing of Bluetooth devices
removes the ability to connect to any previously
paired Bluetooth device. You need to perform
the pairing process again (see page 8) if you
wish to reconnect.
If the streaming was interrupted for more than
30 minutes, it may be necessary to switch the
uMic off and on again.
18
The status light will rapidly blink blue for a few
seconds after pairings were deleted (automatic
pairing mode).

Use of the lanyard
For transportation, you
may use the detachable
lanyard as illustrated.
