No telepresence application is installed on the touch panel.
Step 1 According to the Commissioning Guide to the HUAWEI TP3106 Telepresence System (V100R001C02B011 2011.11.07).docx, set up the touch panel's wireless connection and ensure that it can access the network where the telepresence host is located.
Step 2 Open the touch panel's built-in web browser. In the address bar, enter http://telepresence host's IP address/hid.apk (by default, the telepresence host's IP address is 172.16.21.10) to access the download page.
Step 3 Follow the onscreen instructions to download the telepresence application.
Step 4 Locate the hid.apk file on the touch panel using the built-in file manager (generally, you can find the file in the download folder in the touch panel's built-in SD card).
Step 5 Tap the file to install the application.
During the installation, if the "Unknown sources" message is displayed, choose Settings > Application settings > Unknown sources to allow installation of software from unknown sources.
Step 6 After the installation is complete, start the telepresence host control software and set the telepresence host's IP address.
The touch panel can then connect to the telepresence host.
The telepresence application on the touch panel was deleted inadvertently.
The touch panel was restored to its default settings.
The touch panel is a new one that has no telepresence application installed.
