5.1.1 Connecting a VPM220
The VP220 provides 180° sound pickup and an optimal pickup range of six meters. Use the
10 m proprietary cable provided with the VPM220 to connect the HD-AI connector of the
TE30 integrated cable to the IN port on a VPM220. Once the connection is set up, your TE30
automatically uses the VPM220 instead of its built-in microphone for sound pickup.
The status indicators can quickly provide information about the VPM220 working status.
Table 5-2 describe the status indicators.

5.1.2 Connecting a VPM220W
After a VPM220W connects to the TE30 over Wi-Fi, the TE30 automatically uses the
VPM220W instead of its built-in microphone for sound pickup.
Prerequisites
The Wi-Fi hotspot is enabled and Wi-Fi parameters are set as follows:

The encryption mode is set to WPA-PSK or WPA2-PSK.

DHCP is enabled and Start IP address and End IP address are set correctly.
For details, see Setting Wi-Fi Hotspot Parameters.
Procedure
Step 1 Press the power button at the bottom of the VPM220W to power it on.
The VPM220W automatically scans for available Wi-Fi networks.

If a VPM220W has been connected to your TE30, the connection between the two is
automatically set up, and you can skip the following steps.

If the VPM220W is used for the first time or fails to obtain an IP address, proceed to
Step 2 and Step 3.
