TiVo®Parental Controls help you make sure your family has access to only those shows you want them to watch. From the Home screen, select the Menu icon from the Home screen, then choose Settings > Parental Controls.
TURN PARENTAL CONTROLS ON/OFF
To turn Parental Controls on, use the UP/DOWN buttons on the remote control to enter a four-digit PIN, then enter the same PIN again for confirmation. When you turn off Parental Controls, the PIN is deleted and anyone can watch any show or channel. When Parental Controls are on, a lock icon will appear on the Home screen next to the Menu icon.
