Alerts & Alarms

Alerts & Alarms

Listed below are alerts, alarms and reminders you may encounter while using your device.

Note:Your pump has a sophisticated network of safety checks and systems. If the safety network detects anything unusual, your pump notifies you of conditions that require your immediate attention. The backlight illuminates the pump screen and the alarm or alert message displays on the screen.

Alerts: An alert makes you aware of a situation that may require your attention. An alert is less serious than an alarm. When an alert condition exists, the pump is placed in Special mode and an open circle displays on the pump screen.

Alarms: An alarm warns you that the pump detected something that prevents insulin from being delivered. An alarm means that insulin delivery stopped, the pump has been placed in Attention mode, and a solid circle displays on the pump screen. It is important that you respond to an alarm.
