I love these Sonicsrewdrivers, they are a must for any Whovian. To get the Sonic screwdriver to operate all 8 sounds, a single click will operate 1 of 2 sounds, however click the button 3 times for the third sounds and 4 times for the fourth sounds etc etc, this works right up to 8 clicks for all different 8 sounds. unfortunately the packaging is limited as to what is can tell you about your sonicscrewdriver, however, I hope this handy little hint helps. (also works for several other BBC original sonicscrewdrivers, just try clicking the button more than once or twice).
