I posted this exact question about a year or so ago! You are right, it's not in the instructions but it is very easy fix!
Go to the main drive screen. Touch the fourth "button" from the left on the top row (its black with white circles). It shows all twenty functions. Just touch the function you require, select the type of function (ie light, sound...) and that's you! From then its available.
Hope that helps,
Rob
