Hisense is one of China's top electronics manufacturers. The company produces a range of home appliances and consumer electronics, including several TV models. Each set comes with parental controls for blocking unsuitable channels, shows and movies. The content you designate to be blocked will show up as locked when you try to watch it. You can choose to block particular content based on situations occurring in the show, for example sexual situations or violence, or by the official rating of the program such as G, PG and MA. If you decide that you no longer need the channels blocked you can unlock the parental controls.
Press the "Menu" button on the remote control. The TV menu will appear.
Tap "Channel ^" or "Channel v" to scroll the cursor between the menu options. Select "Function" and press "OK."
Select "Parental Control" and press "OK." Enter the TV's password when prompted.
Choose "Off." The parental controls will switch off and the TV will unlock.
Repeat steps 1, 2 and 3 if you forget your password, selecting "Factory Reset" instead of "Parental Controls." The TV's password defaults to "0000."
