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

change the level of the hearing aid microphones
while using the uMic to adjust the volume of
sounds around you.
Functional test of uMic
Before using the system, perform
a quick functional test by gently
tapping on the microphone
opening.
You should clearly hear the tapping noise in
your hearing aids.
Line of sight between the uMic and the streamer
is usually not required. If the audio transmission
ends abruptly, refer to the troubleshooting
guide.

uMic pause and resume
To pause the audio transmission
from your uMic, press the uDirect 2
access ( ) button.
During pause:
The streaming indicators will blink blue on
both devices.
Your hearing aids will switch back to the most
recent hearing aid program.
The hearing aid programs cannot be changed
via the uDirect 2 access button while
streaming or during pause.
To resume the uMic streaming press the
uDirect 2 access ( ) button again.
Wearing the uMic correctly
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
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.

1918
Special use cases
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.
“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.
Switching the uMic off
To end the uMic transmission
completely, switch off the uMic by
sliding the power switch to the off
position.
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.

2120
uMic streaming distance
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.
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.
It may take up to 10 seconds until the streaming
resumes.
If the streaming was interrupted for more than
30 minutes, it may be necessary to switch the
uMic off and on again.
uMic and watching TV
To ensure a high quality audio
in stereo sound from the TV,
we recommend using the
dedicated 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.
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.

Deleting all Bluetooth pairings
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 the
( ) button and hold the button for
10 seconds. This deletes all pairings.
2. Release 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.
The status light will rapidly blink blue for a few
seconds after pairings were deleted (automatic
pairing mode).
Support of multiple uMics
It is not possible to stream audio from two
uMics to one uDirect 2 at the same time.
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.
If a cellular phone is connected to uDirect 2
already, only one uMic can be supported.
Use of the lanyard
For transportation you
may use the detachable
lanyard as illustrated.
