Hiya
I've also found that the time is out by about 2-3 mins every day as well. I too keep re-setting the time. The date seems to be ok though but if I take out the batteries and then re-insert them because of BSD, when it switches on again I have to re-set the date and time.
I would complain to Accu chek and get them to send you out a replacement Combo remote which they will do foc because the pump is under the warranty. I shall be on remote no 3 soon so am not pleased.
The reminder to do an infusion set change can be switched off or altered depending on how long you want to keep your infusion set for.
