the alarm or CANCEL to acknowledge the alarm. See 'VTBI' section for more details on VTBI operation.
Manual Bolus
The "Manual Bolus" is delivered by moving the plunger drive mechanism forward while the pump is infusing. This method of delivering a
bolus is not recommended as best clinical practice.
The syringe must be confirmed and the plunger mechanism has to move from an engaged position to disengage and then re-engage
position.
A minimum travel of 1mm (leadscrew pitch) must be detected to register.
