Simply select one of the new annoying sounds which include a beep, a 12 kHz electronic noise sound, 15 kHz mosquito tone, a cricket, a doorbell or set it to alternate between all the sounds. Now hide this little non-descript electronic device somewhere where it will never be found and hopefully annoy the most people. Then, quietly laugh to yourself as people frantically search their office trying to discover where the sound is coming from.]]>
