VPM220W network
The VPM220W supports manual and automatic Wi-Fi connection.
Manual connection: When you use the VPM220W for the first time or move it outside
the connected Wi-Fi network range, the VPM220W automatically searches for an
available Wi-Fi network. After you manually connect the VPM220W to the Wi-Fi
network, you need to hold and press the
button on top of the VPM220W for at least
3 seconds and accept the connection request on the videoconferencing endpoint's remote
controlled UI or web interface. The VPM220W then performs the Wi-Fi Protected Setup
(WPS) Push Button Configuration (PBC) authentication with the videoconferencing
endpoint in order to obtain an IP address. During WPS PBC authentication, the three
microphone indicators blink blue in a clockwise direction.
Automatic connection: After the VPM220W first obtains an IP address, it automatically
reconnects after a restart.
2.5 Muting or Unmuting the VPM220W

button on top of the device. For details about the button position,

button to mute the VPM220W. The three indicators then turn red.
If a participant wants to speak during a conference, you can tap this button to unmute the
VPM220W. The three indicators then turn blue.
