How do I send an emergency/other message to my device using CommBox Manage?

Visit https://commbox.glbth.com/login.html to log in to your account, from your dashboard. Click on devices and select the desired devices you wish to communicate with. Click on the options button which is the three small dots at the righthand end of the device row.  Scroll down to 'advanced messaging' where you are able to select an existing message or 'Add New' and then click apply.
