I also did not answer about changing modes. I change modes by a left click
on the chin controller than a right click to wherever I want. It makes a
beeping sound so I do not have to look at the display. I can turn the chair
on or off, drives, tilt, recline, or leg rest up or down. I cannot get
under tables because I sit so high, but that is only a concern when we go
out to eat because I need so much space around me that I get in other
people's way. I have to be fed anyway so getting under the table isn't a
big concern. Joan
