8.4 Maintenance and Testing
• The meter needs little or no maintenance with normal use. It automatically tests its own systems every
time you turn it on and lets you know if something is wrong. For detailed information on troubleshooting the
meter, see Chapter 9, Troubleshooting.
• To test the meter display, turn off the meter, and then press and hold the + button. The display cycles
through colors (red, blue, green, and white). If any part of the display does not change colors, contact
ACCU-CHEK Customer Care Service Center at 1-800-688-4578.
• If you drop the meter or think it is not giving accurate results, ensure your test strips and control solution
have not expired, and then perform a control test.
• Perform a control test with each new vial of test strips.
• If the meter is not working properly, contact ACCU-CHEK Customer Care Service Center at 1-800-688-4578.
