How do I change the code on my OneTouch Meter?
: Press the ON/OFF button to turn the meter on. “CODE” and a number (i.e. CODE 7) appears on the display for several seconds. The code numbers on the OneTouch Test Strip packages range from 1 to 16. If the number on the meter display matches the code number on your test strip package, you may proceed with a blood test. If it is not the same, go on to Step 2. Step 2: Press the C Button. With CODE 7 (example) on the display, press and release the C Button, and the number will increase by one. Continue pressing until the number on the display matches the code number on your test strip package. The meter is now properly coded and you may proceed with the test. From now on, the meter will retain the selected code until you change the code for a new package of test strips.
