No you don't. You can bolus from the pump but to do basal eate changes, change more detailed things at leisure then it is so easy to do from the handset...
Everyday functioning for work can be done from the pump.
Due to the enormous amount of detail available with the insight pump it cannit hd everything on the Insight handset either.
Some things like 15 minute basal rates have to be dine on the 360 degree software and downloaded to the pump.
Me, I dont download at all. Certain actions like cannula fill, tube fill etc have to be done on pump but everything else I do on remote. That is solely because I wear pump on my arm.
