Warning Limits
• You can select hyper (high) and hypo (low) blood glucose limits that best fit your needs.
• Whenever a blood glucose test result is above the hyper warning limit or below the hypo warning limit, the
meter displays a warning.
• Set the hyper warning limit greater than the target range of all time blocks.
• Set the hypo warning limit less than the target range of all time blocks.
• Bolus advice is not available if your blood glucose test result is below the hypo warning limit.
Time Blocks
Time blocks allow you to select settings to take into account the fact that your insulin requirement varies
throughout the day. Using the same values and factors for the day would not necessarily match your insulin
needs and could lead to inaccurate bolus advice recommendations.
The meter comes with five preset time blocks. You may set up to eight time blocks (time periods) depending
on your insulin needs. For each time block, you must set the target range, the carb ratio, and the insulin
sensitivity. You can define all of these values separately for each time block. The meter automatically takes
these values into account.
