The queue ticket stand screen is black, what is wrong?

Keep in mind that the screen may be black if the queuing system is set to only operate during specific hours. Otherwise, here's how to fix the problem.

• Use a narrow tool, such as a paperclip, and push into the hole located under the iPad display in the center of the white frame. If the iPad restarts, it will ask for a PIN code, enter your PIN.
• On the back of the iPad holder there is a round hole in the upper left corner. The hole has an elevated cutting where it is possible to use a needle/paperclip to access the iPad's power button on the top. Hold down the power button for a few seconds to start the iPad.
• Make sure the power cable of the queue is plugged into a working outlet.
