The Explorer 2200 is a digital cable receiver distributed with standard home cable subscriptions from Comcast. The receiver features a parental lock that blocks unsuitable content from underage children. Unblocking content can be done by entering a four-digit PIN code. Unlocking the Explorer 2200, however, removes the parental controls and opens all channels for viewing without the need for the PIN.
Press the "Settings" button on the left side of the remote. This button is found next to the "Left" arrow. A menu appears onscreen.
Tap the "Down" arrow button until "Parental Control" is highlighted. Press the "Select" button located in the middle of the arrow keys.
Tap the "Down" arrow button until "Turn OFF Parental Control" is highlighted. This option will read "Turn ON Parental Control" when the parental control isn't engaged. Press "Select."
Enter your "Parental Control PIN" number using the number keys on the remote. Press "Select" when you are finished.
Enter your "Blocking PIN." Take note that this number is different from the "Parental Control PIN." Press "Select." The icon next to the "Turn OFF Parental Control" text will change to an open padlock. The parental lock is now deactivated.
