Forgot passsword and cannot get in

Good Morning,

My friend has a Digiland tablet, Model #DL808 and is locked out; He cannot can't remember his password. He is severely disabled and asked me to help, however I'm not sure how to reset it? I powered off the unit, then held down the volume and power buttons to boot, but when it comes up there are 6 icons on the screen and I am unable to select any of them. any assistance would be greatly appreciated.

Thank you.
