Connection Status
The icons for wireless connection status and ToolsNet connection status show a live update of the state of the connection. The hand controller will connect to Wifi if it is configured to do so in Settings -> Network.
When wireless is connected and the HC has an active connection to the Wifi network the Wifi connection icon appears without the diagonal line.
When the hand controller is configured for connection to ToolsNet the state of the icon reflects the state of the connection. The diagonal line means that there is no open connection to ToolsNet.
