5.1.1 Connecting a VPM220
The endpoint can be used with a HUAWEI VPM220 microphone array (VPM220).
When installing a VPM220, do not point any microphone towards the speaker.
Status Indicators on the VPM220
VPM220 status indicators quickly provide working status information.
There are three indicators on top of the VPM220 at an interval of 120°.
these three indicators.

VPM220 Cascading
The VPM220 provides 360° sound pickup and an optimal pickup range of six meters. In a
large conference room (of about 40 to 50 square meters) with only one VPM220, audio far
from the VPM220 becomes problematic; cascaded VPM220s can help alleviate this problem.
Dynamically cascading, connecting, or disconnecting VPM220s will not interrupt a
conference.
The TE80 can be connected to two cascaded VPM220s.
