1 Overview
About This Chapter
The HUAWEI VPM220W wireless microphone array (VPM220W) is a wireless audio pickup
device that can seamlessly integrate with HUAWEI TEX0 series videoconferencing endpoints
and HUAWEI DP300 videoconferencing endpoint.
The VPM220W uses three microphones spaced 120 degrees apart, offering 360-degree audio
pickup at a radius of up to 6 meters. The VPM220W offers premium audio input to
videoconferencing endpoints, significantly contributing to a more pleasant conference
experience.
1.1 Features
Flexible Access
The VPM220W connects to a videoconferencing endpoint over Wi-Fi. When you use the
VPM220W for the first time, you will need to manually search for an available Wi-Fi
network. The next time you use the VPM220W, it automatically connects to the same
endpoint.
The VPM220W can be easily moved based on the number of meeting participants and
the layout of the venue. This avoids the inconvenience associated with wired
microphones.
The VPM220W network is simple and because its microphones directly communicate
with the videoconferencing endpoint over Wi-Fi, it ensures stable signals and strong
anti-interference capabilities. However, the VPM220W does not support cascading.
Reliable and Easy to Use
The VPM220W has a mute button on top of the device. Tapping the mute button will
mute or unmute all the VPM220Ws of the same site.
You can use the VPM220W directly after it starts up without performing any additional
configurations.
The VPM220W is equipped with a rechargeable battery and comes with a charger base
that can recharge one or more VPM220Ws simultaneously. A fully charged VPM220W
provides up to 8 hours of active time and 24 hours of standby time.

You can easily store and maintain the VPM220W without disconnecting cables. Incorrect
cable disconnection may lead to microphone unavailability.
High-Quality Audio
The VPM220W supports 360-degree audio pickup at a radius of up to 6 meters.
The VPM220W delivers high-quality audio using frequency compensation technologies.
The VPM220W supports both mono and stereo applications.
Low Power Consumption
The VPM220W utilizes an energy-efficiency design. It consumes less than 2 W of power
in active mode and less than 0.7 W in standby mode.
Videoconferencing endpoints, rather than the VPM220W, perform audio processing,
which reduces the VPM220W's power consumption.
1.2 Components
Unpack the product and ensure that all the necessary components are included.
Table 1-1 lists the VPM220W components. If you have purchased optional accessories, check

2.1 Appearance
Figure 2-1 shows the VPM220W.
Figure 2-1 VPM220W
The VPM220W is plate-shaped with three microphones spaced 120 degrees apart. On top is a
mute button, a battery indicator, a Wi-Fi indicator, and three microphone indicators. You can
mute or unmute all the VPM220Ws of the same site by tapping the mute button. The
VPM220W has a power switch on its base. You can turn off this switch if the VPM220W is
not to be used for a long period of time. For details about the indicator status, see 2.6
Checking Indicators.

2.2 Placing the VPM220W
The VPM220W has arc-shaped rubber pads on its base to prevent it from sliding. You can
place the VPM220W on a conference table. To ensure optimal voice quality, pay attention to
the following:
Place the VPM220W on a stable surface and keep it away from obstacles so that it can
effectively pick up sounds.
Place multiple VPM220Ws in a large conference room to ensure that all participants can
be heard.
Speak into one of the VPM220W microphones, but do not move the unit.
2.3 Turning On or Off the Power Switch
Turn on the power switch to start the VPM220W.
After the VPM220W starts, it requests an IP address. All three microphone indicators turn
blue and blink in a clockwise direction. Once the VPM220W obtains the IP address, the three
microphone indicators become:
Steady blue when microphone input is enabled on the videoconferencing endpoint.
Steady red when microphone input is disabled on the videoconferencing endpoint.
To power off the VPM220W, press and hold the power button for 2 seconds or more.
2.4 Connecting to the Videoconferencing Endpoint
The VPM220W connects to a videoconferencing endpoint over Wi-Fi. Before connecting the
VPM220W to the videoconferencing endpoint, you must enable the Wi-Fi hotspot and the
Dynamic Host Configuration Protocol (DHCP) service on the videoconferencing endpoint to
obtain the IP address of the VPM220W. The videoconferencing endpoint functions as the
DHCP server, and the VPM220W serves as the DHCP client. For details about how to enable
the DHCP service, see the user guide for the HUAWEI TEX0 videoconferencing endpoint.
Figure 2-2 shows the network of VPM220W.
