To unlock a General Instrument CFT2200 box with a parental lock, you typically need to access the settings menu using the remote control. Enter the default or previously set parental lock code; common defaults include "0000" or "1234." If you don't remember the code, you may need to reset the box to factory settings, which will erase all settings including the parental lock. Refer to the user manual for specific instructions on resetting the device if necessary.
