Note: This must be done at the menu item "System Settings?" before selecting it and being asked for the System Pin which you are trying to reset to 0000.
There are no beeps as you enter *65# but when successful, it will display "System PIN Reset" and beep. Your System Pin is now 0000. This is for Siemens Gigaset 2420 reset System Pin to Factory default PIN.
