Getting Started
Before using your Micro Mic, you need to charge the rechargeable battery. To charge it, plug the charging cable into the Micro
Mic as shown in the picture below.
Next, plug the other end of the charging cable into the charger
and into a power outlet.
During the charging process, the status LED indicator will show
a solid red light. When fully charged and still connected to the
charger, the LED will turn solid red, interrupted by a green blink
every 2 seconds.
Charging an empty battery typically takes about 3 hours. It is safe
to leave the charger connected overnight – the battery cannot be
overcharged.
10
400545000-GB-15.10-Rev.A.indd 10 11-11-2015 16:13:31
• When charging your Micro Mic for the first time, let it charge
for at least 3 hours, even if the batter y indicator indicates that
the batter y is fully charged.
• For safety reasons, recharge the battery only with chargers
supplied by ReSound.
Note: To protect the Micro Mic when not in use, please place
i
it in carrying pouch delivered with the product.
Do not charge the Micro Mic while it is on your body.
11
400545000-GB-15.10-Rev.A.indd 11 11-11-2015 16:13:31
Turning your Micro Mic ON and OFF
To turn the Micro Mic ON, press and hold the Power button (see
page 8) for approximately 1.5 seconds, until the status LED turns
green. After releasing the Power button, the status LED will blink
green every 2 seconds.
To turn the Micro Mic OFF, press and hold the ON/ OFF button for
approximately 1.5 seconds, until the status LED turns red – indicating that the unit is shutting down.
If the battery level is low, the status LED will blink orange once
every second.
Pairing to your hearing instruments
Note! The following information is primarily intended for your
hearing care professional, who in most cases will complete the
necessary tasks needed before the Micro Mic can be used with
your hearing instruments. However, the process is designed to be
simple and most people can do it themselves.
It is possible to pair up to three ReSound streaming devices - e.g.
one Micro Mic and two T V streamers (optional Unite™ accessory)
- with a given pair of hearing instruments. Therefore, channel 1, 2
or 3 must be selected when starting the pairing process.
12
400545000-GB-15.10-Rev.A.indd 12 11-11-2015 16:13:31

Pairing the Micro Mic in channel 1
1. Make sure the Micro Mic is turned ON. Your hearing instruments must be OFF – open the battery doors.
2. With the tip of a pen
or similar object, press
the small pairing button once, as shown in
the picture to the right.
The status LED will now
blink orange once every
2 seconds to indicate that
the Micro Mic is ready to
be paired in channel 1.
Your Micro Mic will remain in Pairing mode for 20 seconds.
3. While in Pairing mode, close the battery doors on both hearing instruments and make sure they are ON. A successful
pairing will be indicated by an audible melody being played in
both hearing instruments and the status LED (see page 8) will
stay solid orange for 3 seconds. You are now ready to use the
Micro Mic!
13
400545000-GB-15.10-Rev.A.indd 13 11-11-2015 16:13:32
Pairing the Micro Mic in channel 2 or 3 (For people using more
than one streaming device)
To pair the Micro Mic in channel 2, press the pairing button twice.
The status LED will now blink yellow twice ever y 2 seconds to
indicate that it is ready to be paired in channel 2. Close the batter y
doors on the hearing instruments.
To pair the Micro Mic in channel 3, press the pairing button three
times. The LED will now blink yellow three times every 2 seconds
to indicate that it is ready to be paired in channel 3. Close the battery doors on the hearing instruments.

Start streaming
Turn ON the Micro Mic and make sure your hearing instruments
are turned ON. Streaming can be started in one of three ways.
1. Press and hold the push or toggle button on both hearing
instruments for about three seconds in order to listen to a
streamed audio signal*. If ear to ear program coordination is
activated in you hearing instruments, you only have to activate
streaming on one of the hearing instruments.
2. If you have a ReSound Unite™ Remote Control (optional
accessory), simply press the streaming button
on the
Remote Control*.
3. If you use a ReSound app offering remote control functionality,

*Once the hearing instruments connect to the Micro Mic, a short
“streaming activation” melody will play in your hearing instruments followed by the streamed sound.
Start streaming from a 2nd or 3rd streaming device
If your hearing instruments are paired to more than one streaming device, you can start streaming from one of these devices in
three ways.
15
400545000-GB-15.10-Rev.A.indd 15 11-11-2015 16:13:32
1. Press and hold the hearing instrument program button for
about 3 seconds two or three times in a row to access the 2nd
or 3rd ReSound streaming device.
2. If you use a Unite™ Remote Control (optional accessory),
press the streaming button on the Unite™ Remote Control a
2nd or 3rd time to access the 2nd or 3rd ReSound streaming
device.
3. If you use a ReSound app offering remote control functionality,
simply select the desired streaming program in the program
screen.
Stop streaming
Streaming can be stopped in the following three ways:
1. Push the program button on your hearing instruments once*.
2. If you have a ReSound Unite™ Remote Control (optional accessory), press the “P” button, located in the center of the key
pad*. You may also press the home button to return to your
default settings.
3. If you use a ReSound app, select the desired program in the
program screen.
*This will return the hearing instruments to the last program used.

Volume control
Micro Mic is designed to provide a comfortable listening level
from the moment it is activated. However, for some devices or listening environments you may want to adjust the volume. This can
be accomplished in a variety of ways. Keep in mind that volume
adjustments apply to the streamed signal only.
• Use the “+” and “-“ buttons (see page 9) to adjust volume to a
comfortable level.
Every volume change on the on the Micro Mic will be indicated
by a short blink of the Mute LED. When reaching the ma ximum or
minimum volume level the Mute LED will show a longer (1 second)
steady orange light.

Special features
Drop detection
In the event that the Micro Mic falls from a height of more than 75
cm (30 inches), a built-in sensor will mute the output streamed to
the hearing instruments for up to 2 seconds. This is done to protect the hearing instrument user from ver y loud and unpleasant
impact noise should the unit be accidentally dropped during use.
Volume control lock
If needed, the volume of the Micro Mic can be locked to a specific
level.
When the volume control is locked, it will be fixed to the level it
had when the Micro Mic was powered OFF, but it is still possible
to use the mute/unmute functionality of the device.

Test m ode
The Test mode is primarily intended to be used for pediatric transparency measurements. The transparency measurement evaluates if the hearing instrument and wireless (remote) microphones
provide equal outputs when presented with the same 65 dB SPL
input stimulus.
When in Test mode the microphone is set to omnidirectional
mode with 0 dB gain when placed horizontally in the test chamber. Please refer to relevant guidelines for performing transparency measurements.
How to enter Test mode:
• Make sure the Micro Mic is turned OFF.
• Press and hold the Mute button and the Power button for 1.5
seconds until the status LED turns green and then release the
Power button.
• Keep pressing the Mute button until the green-orange-red sequence is shown on status LED after 10 seconds.
• When in Test mode the Status LED (see page 8) will be solid
orange.
• When entering Test mode the default volume is applied. If
needed, volume can be adjusted on the Micro Mic until transparency has been verified.
26
400545000-GB-15.10-Rev.A.indd 26 11-11-2015 16:13:32
• To exit Test mode and save settings turn off the Micro Mic and
lock the volume control (see Volume control lock section in the
Special features chapter).
Note: Adjustments to reach transparency can be made on
i
the Micro Mic and/or in the hearing instrument using the fitting
software.
