Calculator Error – BA II Plus

Hello,

I am at the very beginning of my CFA Level I studies (currently on the Uneven Cash-Flows section). My issue is that my calculator provides the correct output only under the condition that I reset it before the calculation. I’m under the impression that it’s storing the information from the previous calculations to calculate the the following ones, even if I do 2nd CLR WORK.

Has anybody encountered this issue before?

Many thanks in advance!

Best,

João Sertã.
