@seabass0118 You have to make different profile, than select the profile for your son or,you can create different profiles as many as you want or some genaric.

@SalmanSyed, I'm afraid you are incorrect.  If you look into the manual for this particular model, you'll find that the interface is different, whereby there is no way to add an authorized website.  I recognize how unusual that is, but would refer you to the manual to confirm this feature utterly lacking...

The partental controls are powered by TrendMicro.  The filters go through their servers and dertermine what content to block or allow, based on the pre-made categories or manual entries.  It may not be possible to edit the categories to allow a specific site, but we have contacted our R and D team to find out.  The alternative is to remove the category filter that is blocking the required site and then manually adding filters for the sites that otherwise would be blocked by the category.  

We will let you know when R and D reaches back out to us.
