Sample size for one proportion (prevalence in cross-sectional design)

Hello everybody, and thank you in advance.

I'm trying to calculate a sample size for a cross-sectional;
I want to estimate a prevalence (expected: 5%) with a maximum width 95%CI of 2%.

I see that "power oneproportion" doesn't let you to set the precision of your estimate.
Does anybody know how to fix it?

Thanks again.
Gianfranco
