Projector without remote control

Hello, I bought an Acer X110 projector at a flea market, it works, I connect my computer via a VGA port,
and it works, but to change the input device (e.g. USB) I need to press a button on the remote control, which I no longer have (lost).
What can I do?

Thank you.

  1. look if you have a control panel on the top
    it consists of a central button "menu" and 4 directional buttons
    1. I don't have a control panel

      thank you
      1. Sorry for the delay, but if there is no control panel, we will indeed need to order a replacement remote control.
