Hi @chinoramirez
As there are no other controls on the unit aside from the Power switch, you will need a remote to control its functions.
You could try contacting this [https://www.wish.com/product/idglax-idg-rm002-remote-control-for-dg-737747757-idg-787787w-portable-mini-projector-56d65ce2c8f46b298a72424b|supplier] and ask if they are getting any new stock or if they may know of any other suppliers as they're the only ones that ''used to have one''
