The BlackBerry® AtHoc® desktop app is a small desktop application that continuously runs on your computer. When a new alert targeted at user desktops is published in the BlackBerry AtHoc system, a notification screen pops up on your desktop, accompanied by an audio notification.

You can then close the pop-up or click a link to obtain additional information about the alert. For emergency alerts, the pop-up screen might contain response options that you must select from in order to acknowledge receipt of the alert.
