When two devices are placed close to each other during a Connection Session, a common issue is echoing sound. To ensure a smooth audio and interaction experience, the App is designed with an automatic echo-prevention mechanism.

How the System Prevents Echo

• When the speaker/microphone of the first device is TURNED ON,
  the speaker/microphone of the second device will automatically be TURNED OFF, and vice versa.
• At any given time, only one device is allowed to have its speaker/microphone ON.
