10 11Charging the batteryTo 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.Battery chargingT30Charging ErrorCheckBattery!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.

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)Enable the TT-function on the T31 by pressing the TT button.
