2.7 Switching the Work Mode

When the VPM220W is connected to a videoconferencing endpoint over Wi-Fi, the
videoconferencing endpoint can send a sleep instruction to the VPM220W. Upon receiving
the sleep instruction, the VPM220W enters the sleep mode and stops collecting and sending
audio data, all the three microphone indicators are blue on and off gradually.
You can wake the VPM220W in either of the following two ways:
Send a wakeup instruction to the VPM220W on the videoconferencing endpoint.
Press the
button on top of the VPM220W.
When the VPM220W wakes up, the VPM220W starts to collect and send audio data. All three
microphone indicators restore their previous status.
