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.

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

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).
