To send an announcement to your screen, you must have already connected to the NowSignage App and activated the announcement widget. 

Once this is done, go into your screens dashboard and press 'Actions' and then 'Send Announcement'. 

Here, you can either 'rebroadcast' (if you have created a previous announcement) or create an announcement (if creating for the first time or creating a new one):

If you choose to create an announcement, you can enter the announcement you want to display on this screen under 'announcement message'. You must also choose which screen/s you want to display the announcement on and the date/time you wish it to be sent to the screen (if you leave this blank, it will instantly send the announcement).

Please note -  Announcements will not be visible on the preview mode in your NowSignage account or on either of the browser builds of the app (play/multizone.nowsignage.com).
