Turning On the Speakerphone During a Call
While a call or three-way call is in progress, you can turn on the speakerphone by simply placing your
device face down.
Your device provides crystal-clear sound quality and voice reception during three-way calls. When the
speakerphone is on, your device also enables the dual microphone to enhance your voice quality and
reduce noise.
When you need to temporarily mute the dual microphone so that the three-way call participants will not hear
you, press the
Mute
button. Press it again to unmute.
Turning the Phone On and Off
