Using the Internal Microphone or Earphones with the Bluetooth Phone.
You can use the ECO's internal microphone to speak on the phone if you are able to do this.
Using the Internal Microphone
On the Dial Pad, turn the Microphone option to ON.
Adjust the Mic Level option to make the volume louder or softer.
Remember, if the volume is too loud, you will hear feedback noise.
You can use your CORE overlay whether the microphone is on or not.
Using Headphones
You can plug stereo headphones into the External Headphone connector on the right side of Vantage Lite case, use the spelling overlay or your CORE overlay to speak—and no one will be able to hear your conversation.
Turn the Headphone Level option to ON and set a volume level that is comfortable to listen to.
