Chapter 7: Maintenance And Troubleshooting - Accu-Chek Aviva Owner's Booklet

Meter Maintenance
The meter automatically tests its own systems every time you turn it on and lets you know if something is
wrong. See Chapter 7, Display and Error Messages.
If you have problems with the meter or think the results are not accurate, perform a control test with an
unexpired test strip and control solution. If the control result is not within the acceptable range, contact the
ACCU‑CHEK Customer Care Service Center at 1‑800‑858‑8072.
