Selecting Stair Mode
To select stair mode proceed as follows:
Open the menu.
Select the stair mode option (purple icon).
The wheelchair is now in what is referred to as “stair ready” mode and the sensors, which detect the beginning of the stairs, are active.
If you move the joystick to the left or right (blue area on the LED ring), the wheelchair automatically switches to maneuvering mode (see Maneuvering Mode) and pivots on the spot.
If you move the joystick forward (purple area of the LED ring), the wheelchair scans if a flight of stairs is approaching and triggers the desired transition at the right moment.
(a) On level ground |
(b) On stairs |
Descend stairs in stair mode only
Stair mode must always be activated when climbing stairs. The wheelchair does not automatically switch to stair mode before climbing stairs. Approaching the stairs in any other mode than stair mode may be fatal.
Before switching to drive mode: maintain minimum distance to the edge of the stairs
Make sure that the wheelchair has a sufficient distance of at least 50 centimeters from the edge of the stairs before switching between stair mode and drive mode. In the following situation you should turn the wheelchair 90° using the maneuvering mode (see section Maneuvering Mode) to ensure that you never accidentally drive down the stairs in drivemode:
The minimum distance cannot be maintained due to confined space, e.g. if the upper level is too small or an object is blocking your way.
Never switch to stair mode if the tip of the tracks extend beyond the edge of the stairs or step
When switching to stair mode, the tip of the tracks must always be in front of the edge of the stairs or steps.

Never lean forward or stand up in stair mode
Never lean forward and do not attempt to stand up or get out of the wheelchair when you are in stair mode. There is a risk that the wheelchair could tip forward and fall down the stairs or that you could slip while getting out of the wheelchair.
Only use stair mode when you are on stairs
Never switch to another mode when you are on stairs, even if this may be possible due to an error in the system/software. Always select stair mode.
