Press the system button once and when you see the system and done displayed over the right and left buttons hold them both down for five seconds and that will take you to the setup menu, dont change anything in here just keep hitting the next button till you see the number 670 on the display, once you get to 670 just hit the up or down arrow until the number 0 is displayed next to the 670 your options are 0,1,2,3. after changing it to zero just hit done, you are now unlocked!
