3D Animations from Max: How can I activate an animation at start of scene?

I am using 3DS Max 2011. And I have a 3D Animation of a calculator. The Animation is the cover to the calculator coming off and being placed on the back of the calculator. So I didn;t render it out, yet jsut exported it out as a FBX. Now I just want to have my scene set up so when I click on the calculator, the animation is played. And once that animation is complete, the calculator is now functional with the user. Meaning I can highlight the buttons, etc. But my main focus is the calculator animation working properly.

Thank you,
