The easiest way to find out how to configure the child lock with your remote control is to consult the relevant user’s guide or the salesperson when purchasing a new device or your cable carrier. In essence, the child lock prevents children from watching locked channels until a preset code is entered. You may also lock certain programmes; for instance, you can configure the device not to display shows rated for viewers above 16. In this case, the child lock uses the age-rating of the television stations, so you do not even need to pay attention to the age-limit circle as the television will do it for you.
