Using this Oval HD Lite Brite is a breeze. First, decide whether you want to use one of the 8 HD design templates or create your own design. If you choose a template, place it under the grid. Then, pick up the mini - sized pegs in different colors and insert them into the holes on the grid. You can add as many pegs as you like to make your design detailed. Once you're happy with your creation, insert 3 AA batteries into the unit (remember, batteries are not included). Now, turn on the light and choose from 5 HD light modes. You can watch your art fade, flash, or shine with white light, or enjoy the slow and fast flash animations. For easy display, you can use the stand on the back of the unit or hang it on the wall using the keyhole. As for maintenance, keep the unit in a dry place and avoid getting it wet. If the pegs get dirty, you can wash them gently with mild soap and water and let them dry completely before using them again.
