Preparing yourAmigo 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 T20/T21 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.
Charging the battery
To charge the battery, plug in the charger as
shown in the picture.
The Amigo T20/T21 uses one AA rechargeable
NiMH battery, which must be charged for 14
hours before being used for the first time.
The T20/T21 offers failsafe charging, which
prevents alkaline batteries being charged.
Charging Error
Check
Battery!
The display on the T20/T21
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.

If you do not have time to charge the battery that came with the T20/T21, 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 in an emergency, i.e. if you don’t have time to charge your rechargeable
batteries. Alkaline batteries cannot be recharged.
Note: Always dispose of old batteries in approved battery disposal bins.
For more information please consult your Hearing Care Professional. Note: Selecting a country will also select a predefined channel list, which contains all
of the channels approved for use in that country.

Note: Since Amigo receivers draw their power from the hearing instrument battery,
there is no reason to try to open the receiver casing. Never attempt to do this.
Changing the pin orientation
If the pins on the Amigo receiver do not match the holes on the audio shoe, they can be
rotated in steps of 90°.
Simply pull the tab on both sides of the receiver back simultaneously, move the pins
and push the tab back in.
Amigo receivers can be positioned with the LED facing to the front or the back.
Note: To ensure optimal antenna performance, the Amigo receivers must be positioned
with the LED facing either to the front or to the back.

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 ▲
or ▼to change channel. Press the SYNC button to
confirm the choice of channel. The transmitter will
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 return you to the main menu.
Whenever you need to change channel, simply repeat
the procedure.
SynchronisingAmigo receivers
Connect the receiver to a hearing instrument, and turn it on. Check that the receiver
switch is set to the correct mode, i.e. FM only or FM+HA mode.
Off FM-only FM+HA
Within a distance of approximately 50 cm, press the SYNC button. 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 T20/T21 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 in perfect harmony
• The child is on the right channel
Synchronising other manufacturers’ receivers
The T20/T21 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
T20/T21 by pressing either the ▲or the ▼button. The system should then be working.
