Within this user guide the uDirect 2 is shown  
as an example. As the uMic transmitter is based  
on Bluetooth® technology, other Bluetooth  
receivers may be compatible. However, the  
uMic is optimized and tested only for Unitron

Getting started  
Charging the uMic  
The system consists of three main elements:  
Your uMic has a built-in, non-removable  
rechargeable battery. When the battery is low,  
the indicator light will blink red.  
• uMic  
• Unitron hearing aids  
• Unitron uDirect 2  
To charge:  
The uMic transmits the speaker’s voice  
wirelessly to your hearing aids via the uDirect 2  
streamer.  
1. Insert the Unitron  
power supply  
provided with the  
uDirect 2 into the  
uMic mini-USB  
socket.  
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.  
2. Plug the power supply into a power outlet.

Typical charging time is 2 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.

position.  
The uMic can be charged  
while uTV 2 is being  
used.  
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.

If the uMic has never been paired before,  
pairing mode will be automatically activated  
after turning it on.  
Before using the uMic with a streamer for the  
first time, the devices must be paired with each  
other.  
To manually start pairing mode:  
1. Switch the uMic off.  
If you are not using uDirect 2but another  
streamer, please follow the Bluetooth pairing  
procedure of that device.  
2. Press and hold the volume up

both devices turn solid blue. This  
may take up to 30 seconds but  
usually occurs within 5 seconds.  
For a more detailed explanation of the uDirect 2,  
please refer to the uDirect 2user guide.  
The uDirect 2 will confirm the connection via  
spoken notifications or beeps in your hearing  
aids, depending on the uDirect 2configuration.  
If the status light is rapidly blinking blue after  
turning on the uMic or if the status light does  
not turn solid blue within two minutes, repeat  
the pairing.

Functional test of uMic  
Setting the uMic volume  
Before using the system, perform  
a quick functional test by gently  
tapping on the microphone  
opening.  
To change the uMic volume:  
1. Speak into the uMic from a 20 cm (8”)  
distance.  
2. Use the volume (  
) buttons  
You should clearly hear the tapping noise in  
your hearing aids.  
to set the uMic volume to a  
comfortable volume level.  
Line of sight between the uMic and the streamer  
is usually not required. If the audio transmission  
ends abruptly, refer to the troubleshooting  
guide.  
If your hearing aids pick up too much ambient  
noise, use the following 2 steps to give the uMic  
more focus:  
1. Reduce the hearing aid volume by  
pressing the uDirect 2( ) button.  
2. Then increase the uMic volume by  
pressing the uMic ( ) button.  
The uMic volume setting will be  
stored even when switching off the uMic.  
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  
 
Wearing the uMic correctly  
uMic pause and resume  
1. Gently press to open the clip.  
To pause the audio transmission  
from your uMic, press the uDirect 2  
access ( ) button.  
2. Ensure the uMic is clipped  
securely to clothing as shown in  
the picture .  
During pause:  
3. To prevent scratching sounds,  
do not cover the uMic with  
clothing during use.  
The streaming indicators will blink blue on  
both devices.  
Your hearing aids will switch back to the most  
recent hearing aid program.  
Distance to the speaker’s  
mouth:  
The hearing aid programs cannot be changed  
via the uDirect 2access button while  
streaming or during pause.  
Best results are achieved  
at 20 cm (8’’)  
Do not exceed 50 cm (20’’) for consistent  
audio  
To resume the uMic streaming press the  
uDirect 2 access ( ) button again.  
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.  
16  
17  
 
Switching the uMic off  
Special use cases  
To end the uMic transmission  
completely, switch off the uMic by  
sliding the power switch to the off  
position.  
uMic and phone calls  
Phone calls via Bluetooth will always take  
priority over the uMic streaming.  
If uDirect 2 is paired with your mobile phone,  
you can still receive phone calls, even when  
using uMic. In case of an incoming call, uDirect 2  
automatically stops transmitting the audio  
signal from your uMic and and sends the signal  
from your mobile phone to your hearing aids  
instead.  
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.  
“click”  
To accept an incoming call, briefly press the  
uDirect 2 access ( ) button once you hear the  
ringtone through your hearing aids. Press the  
access button again and the phone call will end.

uMic and watching TV  
uMic streaming distance  
To ensure a high quality audio  
in stereo sound from the TV,  
we recommend using the  
dedicated uTV 2.  
The uMic transmitter supports operation up to  
a range of 20 m (60 ft). Line-of-sight between  
your uDirect 2 and the uMic is not required.  
Interference in the environment by walls, the  
furniture or the human body may reduce the  
operating range.  
uTV 2  
In cases where an analog TV-  
audio output is not available  
or while travelling, the uMic may be used to  
improve the sound quality while watching TV.  
If the uMic is moved out of range of the  
uDirect 2,.the wireless audio transmission will  
be interrupted or even terminated. If the uMic  
is then moved back into range of the uDirect 2,  
it will automatically resume streaming to your  
hearing aids.  
For best results:  
1. Try to locate the TV  
loudspeaker.  
2. Place the uMic 20 cm (8’’)  
from the speaker.  
It may take up to 10 seconds until the streaming  
resumes.  
3. Consider leaving the  
uMic  
If the streaming was interrupted for more than  
30 minutes, it may be necessary to switch the  
uMic off and on again.

watching TV.

Support of multiple uMics  
Deleting all Bluetooth pairings  
It is not possible to stream audio from two  
uMics to one uDirect 2at the same time.  
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.  
However, two uMics can be paired to uDirect 2  
and then accessed sequentially by pressing  
the uDirect 2 access button. With each press,  
the uDirect 2 selects the next uMic in a fixed  
sequence.  
1. Turn the uMic on while pushing the  
(
) button and hold the button for  
10 seconds. This deletes all pairings.  
2. Release the ( ) button when the  
blue indicator light turns green.  
If a cellular phone is connected to uDirect 2  
already, only one uMic can be supported.  
Deleting the pairing of Bluetooth  
Use of the lanyard  
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.  
For transportation you  
may use the detachable  
lanyard as illustrated.  
The status light will rapidly blink blue for a few  
seconds after pairings were deleted (automatic  
pairing mode).
