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 T20/T21 can then be used to charge the battery. Standard disposable Alkaline batteries cannot be charged in the unit. Note: The positive and negative ends of the battery may appear similar, so do doublecheck 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. Battery charging The display on the T20/T21 will indicate when the unit is charging. Also, the LED will turn on and shine green.
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.
Select language and country (first time only) Turn the transmitter on by pressing and holding the On/Off button for two seconds. Press ▲ or ▼ to select language, and confirm by pressing the SYNC button. To select your country, use the ▲ or ▼ buttons, and confirm by pressing the SYNC button.
The Amigo Receivers LED status indicator 3-position mode switch Channel seek/toggle (R2 and R7 only) Europin connector Europin rotation lock Note: Since Amigo receivers draw their power from the hearing aid 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.
Attaching universal Amigo receivers to a hearing instrument Amigo R1 and R2 receivers are attached to the hearing instrument via an audio shoe. First attach the receiver to the audio shoe. Then attach the audio shoe to the hearing instrument.
Using Amigo with the dedicated R7 receiver for Oticon Sumo hearing instruments • Sumo detects the receiver and disables the telecoil if the receiver is on • Operate the receiver from the hearing instrument 2 = FM only 1 = FM+Hearing instrument M = Hearing instrument only SUMO DM with the dedicated, Amigo R7 receiver. The use of the telecoil with the receiver attached requires that the receiver is set to the OFF position.
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.
Synchronizing Amigo 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 2 feet, press the SYNC button. The LED on the transmitter will then blink three times, and the SYNC logo will appear on the screen. If thethe synchronization is successful, the receiver will also blink three times.
When the receiver’s LED is on, it confirms that: • • • • The hearing aid battery is ok The receiver is on The transmitter and receiver are working together correctly The child is on the right channel 18
Synchronizing other manufacturers’ receivers The T20/T21 are compatible with most other manufacturers’ receivers. However, only Amigo receivers can be synchronized wirelessly by Amigo T20 or T21 transmitters or the Amigo WRP. To ascertain whether an FM signal is present you must ensure that both the transmitter and the receiver are on the same channel. Determine which channel the receiver is operating on, and change the channel on the T20/T21 by pressing either the ▲ or the ▼ button.
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.

Then connect it to the external audio source, e.g.: • Computer/Television • CD/DVD/MP3 player The T20/T21 can be used for narrating aux sessions (TV, Video etc.) Connect the T20 to the external audio source and turn it on. On the T21 press the TT button and set the primary and TT channel. The TT channel must be the same as on the T20. Now the teacher can narrate the session on the T21.

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 aid in front of infants, small children or persons with learning difficulties.
Risk of harm caused by unintentional noise that may muffle important signals System 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.
Battery use: • Always use NiMH rechargeable batteries or alkaline batteries. • Always use batteries recommended by your Hearing Care Professional. • Never attempt to recharge non-rechargeable batteries. • Never dispose of batteries by burning them. There is a risk they will explode and cause serious injury. Safety requirements regarding Direct Audio Input (DAI) • The safety of the use of Amigo with DAI (Direct Audio Input) is determined by the external signal source.
