Preparing your Amigo system
Inserting battery
Remove the battery lid on the back of the transmitter and
insert the rechargeable battery – remember to position
the battery according to the markings (+/ -) on the label.
Then replace the battery lid. The T30/T31 can then be
used to charge the battery that came in the package.
Note: The positive and negative ends of the battery may
appear similar, so do double-check that the battery is
positioned correctly.
10 11
Charging the battery
To charge the battery, plug in the charger as shown
in the picture.
The Amigo T30/T31 uses one AA rechargeable NiMH
battery, which must be charged for 14 hours before
being used for the first time.
The T30/T31 offers failsafe charging, which prevents
alkaline batteries being charged.
The display on the T30/T31 will indicate when the
unit is charging. Also, the LED will turn on and shine
green.
Note: With a typical user pattern it is recommended
to replace rechargeable batteries once every year,
because the battery capacity decreases each time
it is charged.

Charging Error
Check
Battery!
If you do not have time to charge the battery that came with the T30/T31, you can
replace the battery with any of the following:
• Special “silver-banded” rechargeable batteries
(Only available through your hearing care professional, these are the only batteries
that can be recharged inside the transmitter.)
• Standard, rechargeable NiMH batteries
These cannot be recharged inside the transmitter, but must be charged in a separate
charger.
• Standard, non-rechargeable alkaline batteries
Can be used when rechargeable batteries are not available, i.e. if you don’t have time
to charge your rechargeable batteries. Alkaline batteries cannot be recharged and
cannot be purchased from Oticon.
Note: Always dispose of old batteries in approved battery disposal bins. For more
information please consult your Hearing Care Professional.

with the LED facing either to the front or to the back.
Using Amigo R12
• The hearing instrument detects the Amigo R12 and automatically adds two programs
and will default go to the FM+M program.
• If the switch on the hearing instrument is enabled, it is
possible to change program on the hearing instrument.

Choosing and changing channels
To change the transmitting channel on the Amigo transmitter, press and hold either
the ▲ button or the ▼ button for two seconds to select one of the predefined lists of
channels.
When the channel number begins to blink, press ▲

then be locked on to the new channel.
When the channel number is blinking you can return
to the original channel by pressing the C-button.
This will also take you back to the main menu.
Whenever you need to change channel, simply repeat
the procedure.
Synchronising Amigo receivers
Connect the receiver to a hearing instrument, and turn it on. Check that the receiver
switch is set to one of the two ON modes.
Within a distance of approximately 50 cm, press the SYNC button on the transmitter
briefly. The LED on the transmitter will then blink three times, and the SYNC logo will
appear on the screen. If the synchronisation is successful, the receiver will also blink
three times.
Note: The switch on the receivers can be disabled, so use the T30/T31 or the WRP to
check the status. In its default setting, the receiver switch is enabled.

When the receiver’s LED is on, it confirms that:
• The hearing instrument battery is ok
• The receiver is on
• The transmitter and receiver are working together perfectly
• The child is on the right channel
Synchronising other manufacturers’ receivers
The T30/T31 are compatible with most other manufacturers’ receivers. However, Amigo
receivers can only be synchronised wirelessly by Amigo transmitters.
To ascertain whether an FM signal is present you must ensure that both the transmitter
and the receiver are on the same channel.
Find out which channel the receiver is operating on, and change the channel on the
T30/T31 by pressing either the ▲ or the ▼ button. The system should then be working.
Note: To obtain information about connecting your Amigo receivers to Cochlear Implants
and bone anchored hearing solutions, please consult your Hearing Care Professional.

About channels
Your Amigo system is a radio device, and like any other radio, it communicates on specific
channels. Your transmitter and receiver must be on the same channel to work together.
Within a close proximity, never operate two transmitters on the same channel – you will
experience interference.
If you are travelling internationally, be aware that your channel may not be approved
for use in all countries. If you wish to use your T30/T31 in a different country, you must
contact your Hearing Care Professional who can help you change the country set-up.
Some electronic devices (microwave ovens, computers, and flourescent lights, for example)
can interfere with your Amigo signal.
Using the TT-function (T31 only)

audio source, e.g.:
• Computer/Television
• CD/DVD/MP3 player
The T30/T31 can be used for narrating aux
sessions (TV, Video etc.) Connect the T30 to
the external audio source and turn it on. On
the T31 press the TT button and set the
primary and TT channel. The TT channel
must be the same as on the T30. Now the
teacher can narrate the session on the T31.

to wear the microphone around your neck.
Three microphones are available:
• Clip-on directional microphone.
• Boom microphone. The earhook can easily be
attached around one ear, and the microphone
placed close to the mouth.
Note: Since the microphone also acts as the
antenna, users must keep it attached and in
an upright position.
Cleaning of the T30/T31
The T30/T31 is moisture repellent, making it very easy to clean with a damp cloth.
Oticon recommends cleaning on a regular basis.

Appendix A: Troubleshooting
Problem Solution
The battery will not charge Check that it is positioned correctly.
Make sure that it is the “silver-sleeved”
rechargeable type of battery, as this is
the only type the T30/T31 will charge
(for safety reasons).
No sound / no FM reception Check that the hearing instrument battery
is working, and that it is on. Check that
the receiver is on and correctly connected.
Check that the transmitter is on.
Press the SYNC button again.
The receivers cannot be synchronised Synchronisation takes place wirelessly,
so if the receiver fails to confirm (with
three blinks of the LED), try to move
the transmitter closer, further away or
a little bit to one side. Then press the
SYNC button again.
Interference If interference is encountered on a
channel, change to another channel.
Press ▲ or ▼ to change channel.

Warnings
Amigo parts can be dangerous if swallowed:
The Amigo system is not a toy and therefore should be kept out of the reach of children and anyone else
who might swallow parts or otherwise cause injury to themselves. Special attention should be paid to
the smaller components in order to prevent children from swallowing them and choking. Never change the
battery and never connect the receiver to the hearing instrument in front of infants, small children or
persons with learning difficulties.
If a part is swallowed, see a doctor immediately.
Risk of harm caused by unintentional noise that may
muffle important signalsSystem dysfunctions:
The Amigo system will cease to function if the batteries have run out. The system may also produce a high
whistling noise (feedback) if the battery is low, or if it is subjected to loud sound while the microphone is off
but the receiver is still on. Users should be aware that these sounds should not be confused with warning
sounds – e.g. car horns in traffic.
Use on aircrafts:
Amigo should not be used on aircrafts without the permission of the flight crew. Please note that Amigo can
cause interference with other medical devices. Such interference can also be caused by radio signals, power
line disturbances, airport metal detectors, electromagnetic fields from other medical devices and electro-
static discharges. Please, contact the manufacturer of other medical devices for information about the risk
of disturbance.
