Using the Set 900
Switching the microphones on/off
The microphones openings at the sides of the receiver pick up the sounds of your surroundings. When the microphones are switched on, you will hear your surroundings louder. You can hear for example your door bell, your telephone or your conversational partner even when you are wearing the receiver. The microphones can be used in two different hearing situations:
Hearing situation 1:
You want to hear the sound of your sound source and your surroundings.
Hearing situation 2:
You only want to hear your surroundings and you use the receiver as an assistive listening device which helps you to better hear other people.
Switching the microphones on (hearing situation 1 and 2)
Press the microphone button 4.
The microphone indicator 2 lights up. You hear 2 short, ascending beeps and then your surroundings.
Make sure that the microphone openings 5 are not covered!
Hearing situation 2
When you hear a sound source which you do not want to hear, you can switch off the sound transmission as follows:
Press the channel search button 7.
The channel indicator 1 goes off. You only hear your surroundings.
Press the channel search button 7 once more to switch the sound source on again.
