The steps to enter your update calibrations are the same as your initial calibration, including
only entering values in one display device. The only difference is, with update calibrations,
you enter your BG meter value just once.
Like the reminders you received with your initial calibration, if you do not enter your BG meter
values right away, the system prompts you every 15 minutes.
