Marking results with a pre-meal or post-meal marker can provide more information about how food affects your blood sugar, to aid in managing your numbers. You can also use a general marker to identify an alternate site test or post-exercise result. When you review the results in memory, these markers can help you remember what was different about the result. To use a marker:

• When you perform a test you want to mark, do not remove the test strip.
• Press and release the right arrow key to toggle through the marker options. When you mark a pre-meal result, you can opt for a post-meal test reminder. The meter can beep 1 or 2 hours after you test to remind you—choose your preference in the set-up mode.
• When the marker you want to use appears, remove the test strip from the meter.
