Privacy mode helps you to operate the badge like a telephone handset.
The badge lets users switch to privacy mode to ensure privacy or use the badge in a high noise environment without a headset. When the badge is in privacy mode, you can use it like a telephone handset.
Press the Call button to make a call or answer a call, and then put the badge speaker to your ear and speak into the primary microphone located on the front of the badge at the top right corner. Only the primary microphone is enabled in privacy mode; the three noise-canceling microphones are automatically disabled.
