Firstly ensure in your 'Appts config' you have set a location alias.
You can set this under 'Terminal Options' > 'General'. Turn on 'Use Location Alias'. You will need to update this if you change rooms at any point. You can add any information you may want it to display such as your name.
Then once the patient has arrived you will be able to send the patient in. This will then display on your patient call screen.
