Enabling proxy setup screens

To enable proxy setup screens:

Log in as the admin user using WinSCP.
Open the system.prop file in the ~admin/java/vm/vame folder.
Ensure the file contains these lines:
```
ipconf11=com.workbrain.devices.edatacollect.screen.setup.ProxyTypeSetupScreen
```
```
ipconf12=com.workbrain.devices.edatacollect.screen.setup.ProxyIPSetupScreen
```
```
ipconf13=com.workbrain.devices.edatacollect.screen.setup.ProxyPortSetupScreen
```
The properties can have the form ipconf<XX>, where <XX> represents the order the setup screens are displayed on the WB5500. The proxy setup screens do not have to be 11 to 13, however, they should follow the convention that each entry is incremented by one over the previous entry, creating a numbered list of setup screens. Ensure the numbers are unique, not used by another ipconf property. The proxy setup screens should be displayed after the clock IP and DNS setup screens.
Add the lines if they are not in the system.prop file, ensuring they have the form ipconf<XX>, where <XX> is unique and incremented by one over the previous ipconfXX entry.
Press Ctrl + S to save.
Press ESC to exit.

You must wait for WinSCP to transfer the file before rebooting the clock. WinSCP will temporarily display a pop-up, listing files to be transferred. When this pop-up closes, the file has been transferred and you can reboot the clock by pressing Ctrl+T and specifying reboot in the console prompt.
