They gave me a huge manual with mine, but once set up it is easy, have you got help yet? I could scan some details, or at least the bit about setting up the time blocks. I set mine to synchronise with mealtimes, so I have 5 timeblocks: breakfast, lunch, dinner, before bed and overnight. The results on the graphs are then comparable.
I love it, some glitches, but better than any other and I know the calculations are correct. Before that I used an insulin calculator app and diabetes diary, but my DSN couldn't cope with the results!
Best of luck!
