Open the app and click the "gear icon" (bottom left) to go to 'Settings'.
If necessary, enter a recognisable name for the device at 'POS device name' (e.g. cash register at bar). Click "OK".
At 'Server name/IP address' enter the IP address of the server. Click "OK"
After completing the form, a message appears stating that the device has been successfully registered on the server. You can return to the login screen via the arrow in the top left-hand corner
Use the login code to log in and use the app
