4.2.3 Standing function
The standing function makes it possible for you to stand up in the wheelchair.
When you stand up, the maximum speed of the wheelchair is reduced
automatically. This may be indicated with a turtle on the display of the
control panel.
The wheelchair's centre of gravity changes when you change the position of
the seat and the backrest. When you use the standing function, you decrease
the wheelchair's stability.
Drive extra carefully when standing
