How do I perform a factory reset (System Reset) on the Pioneer DEH-S7200BHS?

Press and hold SRC/OFF until the unit turns off, press the M.C. dial to display the main menu, turn the M.C. dial to select [INITIAL], then select [SYSTEM RESET] and choose [YES] to initialize the unit settings. The unit will restart automatically after the reset. Note that once the speaker mode is set, it cannot be changed unless the default settings are restored through this process. (Page 6-7)
