   Under very rare situations, the Dexcom G6 touchscreen receiver may not provide high or low glucose alarms/alerts as designed, which can result in two different conditions. First, if a receiver operating system .net error occurs when an alarm/alert should be triggered, the initial alarm/alert will not be delivered until a subsequent alarm/alert is triggered. At that time, the initial alarm/alert is delivered, but not the second one. Alarm/alerts will continue to be delayed and be one alarm/alert behind, causing delayed alarm/alerts until the receiver is reset. This condition could result in the missed detection of a hyperglycemic or hypoglycemic event. Second, a single EGV reading may be delayed for 5 minutes after the initial .net operating system error. If the user receives a single EGV reading delayed by 5 minutes, the delay is not expected to cause user harm.
