Phone audio settings 

On the Phone settings screen you can choose how you want to send your voice and where you will hear your callers. 


This drop down box lists all the audio devices you have connected to your communication aid. This allows you to send your call audio through either your device’s speakers, or another device like headphones or a Bluetooth speaker. Your options may differ from the screenshot below, depending on which device you have.

Choose where you want to send audio from. Your device will often have a microphone built in, and you can also select any connected headsets. No matter what you choose, you will always be able to send Grid’s voice directly. Your options may differ from the screenshot below, depending on which device you have.

There is also a toggle to use the phone speaker and microphone, this will disable Grid’s audio being sent to the phone.

Echo Cancellation 

The close proximity of the device speakers and microphone, when using them for phone use, can lead to an echo on the receiver’s end. We have included software options to help mitigate the echo, if present. Note: this may reduce the overall volume of the user, or make other people speaking in the background inaudible.  

Echo cancellation is only available when Grid voice only is not selected in the Microphone drop down menu and has three levels: low, medium and high.
