How do you stop programs from auto loading on a pda??

I have been given a pda for work, symbol mc 35, made by motorola, and we are testing it but i want to know how i can stop the software we use for work fromn auto loading... if i reset it i get about 30 seconds to play with the settings before the program loads. we are trialing the pda to see if it is any good and i want to access the pda software its self.
