Chapter 12 Using Advanced Features
Using the features in this chapter requires an advanced understanding of insulin pump
therapy and should not be used without training and advice from your healthcare team.
In order to achieve optimal results, some of these features should only be used once you
have tested and fine-tuned your basal rates and your healthcare team has determined
your individual targets and ratios.
Note: Before using these features, you must turn them on in the Setup Advanced Menu. See
Chapter 11.
Audio Bolus and ezBolus
The Audio Bolus feature of the 2020 allows you to bolus without looking at the screen
display. This is convenient if you wear your pump under your clothing. When first using
the audio bolus feature, also check the display screen until you are comfortable with the
programming steps. If you do not wish to use the Audio Bolus feature, this button serves as
a shortcut to the Normal Bolus screen. See next section, ezBolus.
When you first use the Audio Bolus feature, you should always look at the screen to
confirm correct programming until you are comfortable with the feature.
1. Turn on Audio Bolus in the Setup Advanced menu and select your preferred step size.
See Chapter 11, Advanced Features.
2. The Audio Bolus button is a soft rubber button on the end of the pump. Press it once.
The pump will beep (or vibrate) to indicate you’ve accessed Audio Bolus mode as well as
indicate the step size you’ve set up.
The number of beeps (or vibrate pulses) reminds you of the step size you’ve set.
• 1 indicates 0.1 U step size
• 2 indicates 0.5 U step size
• 3 indicates 1.0 U step size
• 4 indicates 5.0 U step size
3. Press the audio bolus button once for each step size you’ve
programmed to reach the desired total amount. For example, if you
are using 1.0 U step size and you wish to bolus 4 units, press the
button 4 times. You will hear a beep tone for each button press. If
you are using 0.5 U step size and you wish to bolus 4 units, press
the button 8 times.
4. Within 5 seconds, the pump will respond with a number of confirmation beeps equal to
the number of times you pressed the audio bolus button.
Note: Do NOT press any of the function buttons at this time unless you wish to cancel
delivery.
