Alarms If necessary, ODA will alert divers by flashing . It is divided according to severity into notifications and alarms . Notifications – operational notifications, such as setpoint change, end of no-decompression time, etc . Signalled by a short white flash . The value to which it applies is highlighted . The notification is accompanied by a pop-up message .
