If the screen does not respond correctly when you

a

Holding your finger on the screen, turn the 
main power switch to OFF and back to ON.

Using the included touch pen, lightly touch 
the center of each +, in order from 1 to 5.

Turn the main power to OFF, then turn it 
back to ON.

Note

• Only use the included touch pen to touch the 

screen. Do not use a mechanical pencil, pin, 
or other sharp object. Do not press strongly 
on the screen. Otherwise, damage may
