 The speech processor test device shows if your RONDO 2 is working correctly or not. Switch on your RONDO 2. Place the flat side of RONDO 2 under the speech processor test device. Speak into the microphone. The indicator light should flicker to the rhythm of your voice. If the indicator light doesn't flicker, adjust the volume of your voice. If it still doesn't flicker, completely charge your processor. Switch it on, then speak into the microphone again. If your RONDO 2 still isn't working or for immediate assistance, contact your CI Center.
