A standard 101 style keyboard (with a standard USB connection) or a wireless keyboard can
be connected to the WM4 to access certain menus during setup and fault finding. Users
should not access the machine and attach a keyboard unless specifically requested to by
instructions in this manual or verbally when in contact with your Alcolizer Technology
technical representative.
Access the USB ports by unlocking the WM4 and swinging it open. There are four ports
located on the main circuit panel.
Once the keyboard is connected, access to the menu is available. The keyboard functions
