Unfortunately, there isn't any guide available for RM Easiteach Virtual Handset Plugin. The only video tutorials provided by the developer describe Easiteach features. However, this plugin allows pupils to vote from their computers and it is easy to install and use. Firstly, you need to install the plugin on the computer where Easiteach is installed and then to install the handset on each pupil computer. In order to connect, you will need to select the pupils PCs from the drop-down list from Easiteach interface. Check the official web page for further information.
