Getting Started
Charging the Battery
Before using your Interton Mini
Microphone, you need to fully
charge the rechargeable battery.
To charge it, plug the charging
cable as shown in the picture to
the right. Then plug the other end
of the charging cable into a power
outlet.
During the charging process, the
LED indicator will show a solid red
light. When fully charged and still
connected to the charger, the LED
will turn solid green interrupted by a
red 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.
• When charging your Interton Mini Microphone for the first time,
leave it to charge for at least 3 hours, even if the battery indicator indicates that the battery is fully charged.
10
• For safety reasons, recharge the battery only with chargers
supplied by Interton.
Do not charge the Interton Mini Microphone while it is on
your body.
Turning your Mini Microphone ON and OFF
To turn ON your Interton Mini Microphone slide the ON/OFF
switch (4 on page 8) down to the ON position. A white”I” icon will
be visible on the switch and the LED indicator will now blink green
every 2,5 second.
To turn it OFF, slide the ON/OFF switch up to the OFF position.
The LED will now stop blinking.
If battery level is low the LED will blink yellow every 2 seconds.

Pairing to your hearing instruments
Note! The following information is intended primarily for your hearing care professional, who in most cases will complete the tasks
that are necessary before the Interton Mini Microphone 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 Interton streaming devices - e.g.
one Mini Microphone and two TV streamers (optional Interton
accessory) - with a given pair of hearing instruments. Therefore,
channel 1, 2 or 3 must be selected when starting the pairing
process.
Pairing the Mini Microphone in channel 1
1. Make sure Interton Mini Microphone is turned ON. Your hearing instruments must be OFF – open the battery door.
2. Remove the silver cap from the Mini Microphone. With the
tip of a pen or similar object, press the small pairing
button one time on the front of your Interton Mini Microphone (see picture on the next page). The LED will
now blink yellow once every 2 seconds to indicate that
is ready to be paired in channel 1. Your Interton Mini Microphone will remain in pairing mode for 20 seconds.
12
3. While pairing mode is activated, close the battery doors
of both hearing instruments and make sure they are ON. A
successful pairing will be indicated by an audible melody
played in both hearing instruments.
You are now ready to use the Interton Mini Microphone!
Pairing the Mini Microphone in channel 2 or 3
To pair the Mini Microphone in channel 2, press the pairing button
twice. The LED will now blink yellow twice every 2 seconds to
indicate that it is ready to be paired in channel 2. Close the battery
doors on the hearing instruments.
13
To pair the Mini Microphone 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
Pairing blinking pattern:
1. Press and hold the push button on both hearing instruments
for about three seconds in order to listen to the streamed
audio signal. Once Interton Mini Microphone has been connected an audible melody will play in your hearing instruments
and will be followed by the streamed sound.
Turn on the Mini Microphone and make sure your hearing instruments are turned on as well. Streaming may be started in one of
two ways.
2.If you have an Interton Remote Control (optional),
simply press the Interton streaming button. Doing so will
briefly show a search icon in the remote control display. Once
the hearing instruments connect to Interton Mini
Microphone, a short melody will be played in both ears to
confirm the presence of streamed audio and a streaming
icon will appear in the display. The streamed sound can now
be heard in your hearing instruments.
14
15
Start streaming on a 2nd or 3rd Interton Mini Microphone
unit
If your hearing instrument is paired to more than one streaming
device, you can start streaming in two ways.
1. Press and hold the hearing instrument push button for about
3 seconds a 2nd or 3rd time to access the 2nd or 3rd Interton
streaming device.
2. If you use an Interton Remote Control, press the streaming
button on the Interton Remote Control a 2nd or 3rd time to
access the 2nd or 3rd Interton streaming device.

Stop streaming
• With the Interton Remote Control (optional) you just have to
press the “P” button, located in the center of the key pad. This
will return the hearing instruments to the last program used.
You may also press the home button to return to your default
settings.
• If you are using the telephone with Interton Phone Clip, streaming of Interton Mini Microphone will be temporarily disrupted.
When you have ended your phone call, streaming will resume.
Note! You may get out of range (>7m) from your Interton Mini
Microphone. If you get back in range within 5 minutes,
your hearing instruments will automatically reconnect
and continue streaming.
Wearing Your Interton Mini Microphone
Clip your Interton Mini Microphone on the speaker’s jacket or
other clothing. Place the device within a range of 10-20cm from
the speaker’s mouth.

Light Indicator (LED)
Using the Line-in
The Light indicator (6 on page 9) on your Interton Mini Microphone
serves as a multipurpose user interface, providing information on
the status of your device.
The Line-in (3 on page 8) can be used to stream audio signals
from most auxiliary audio devices through the Interton Mini Microphone’s line input directly to your hearing instrument
1 Insert the included jack cable into the Line-in plug on the
Interton Mini Microphone.
2 Plug the other end of the jack cable into the AUDIO OUT on the
audio device you want to stream from.

Note: When using the Interton Mini Microphone with a
TV the HEADPHONE output terminal is usually located
on the side or front of the TV. When using the HEADPHONE output terminal on the TV, usually only the person
wearing the hearing instruments will hear the sound, and the
TV speakers are muted. Your TV may support speakers and
HEADPHONE being on simultaneously, check your TV manual for
instructions.
Volume Control
Interton Mini Microphone has been designed to provide a
comfortable listening level from the moment it is activated.
However, for some devices or listening environments it may be
desirable to adjust the listening volume. This can be accomplished in a variety of ways. Keep in mind that volume adjustments apply to the streamed signal only, not the volume of normal
environmental sounds.
• Use the “+” and “-“ keys (5 on page 9) to adjust volume to a
comfortable level. Make sure that your hearing instruments are
comfortably adjusted before you change the settings with the
volume control.
Note: When using the Mini Microphone as a microphone
the last volume setting will be stored. When using the
Line-in, the volume setting will revert to the default level
when the Mini Microphone is turned OFF and ON again to avoid
an uncomfortable loud initial sound level when used with different
audio sources.
20
21
• Use the Interton Remote Control (optional) to adjust the
streaming volume in the hearing instrument. Ask your hearing
care professional for more information about this accessory. • The volume can in some cases be further adjusted at the
signal source, for example by turning the TV itself down.
In many cases this will adjust the volume of both streamed
audio (transmitted wirelessly to your hearing instruments) and
non-streamed audio (sounds reaching the hearing instrument
microphones in the normal fashion). Of course, this will also
affect listening volume for others in the room.
22
