ACCUE Chek Aviva

Good morning:

I had a manual in which the way of putting the memory was reflected, but I have lost it and now in the new manual does not appear as to perform it.
Navigating Internet indicate that its use for security reasons is prohibited, I mean that the "fudge" do not walk.
If anyone knows how to do it I would appreciate it.I remember it was through a combination of keys but I don't remember it.
I know that he records up to 500 measurements but in my case, I wanted to put them at 0. Greetings.

Have you tried to remove the battery?

In this link you can download the manual:

I have already done it and nothing, in an old manual towards it with a combination of the keys of the accu chek but regret it a lot I have lost it and in the current one that you have indicated to me no longer appears, I hope news of the users about it.
