Hello! Can you please help me....My father in laws wheelchair came in today......we were having a hard time figuring out what to do to let it move at first. Then I was able to slow down the speed, but the Joystick is horrible....So hard to maneuver left to right and vice versa....It won't really drive straight for long. what is this???? Also the mode is on Attendant...how do you put this to Indoor Mode? Is there any way to adjust the joystick to maneuver the chair the right way? Thanks!
