[Limdep Nlogit List] How to fix certain coefficients at zero for Latent Class Model?

Dear All,

I am trying to fit a latent class model with 2 classes.  Part of the
code is listed below

Rh2=one, Age, Male, Alcohol, Belt,Speed;

The p-value results show that some coefficients are not significantly
different from zero. So I want to fix those coefficients at zero, for
example, fixing the coefficient for Class 1 and Choice B at zero. Can
anyone kindly tell me how to do this? Also, in latent class model, how
can I set the base alternative? Thanks.
