Troubleshooting
The OneTouch® Ultra® 2 Meter displays messages when there are problems with the test strip, with the meter, or when your
blood glucose levels are higher than 600 mg/dL or lower than 20 mg/dL. Messages do not appear in all cases when a problem
has occurred. Improper use may cause an inaccurate result without producing an error message.
