P·9
• Do not mount steps when they are damp or slippery.
• Verify the strength of the step-nosing strips on stairs, they must be firmly fixed with a
rigid fixation.
2.3.3. Using ‘automatic stairs’ mode
The ‘automatic stairs’ mode automatically takes charge of the wheel-sets and simplifies the
user’s manipulations. However, this mode uses optical sensors. Do not use this mode when
the sensors may provide incorrect information, particularly in the following cases :
• Glass steps
• Open staircases
• Steps covered with highly reflective material
• Uneven or decorated steps.
DANGER !
If you must traverse these conditions you will need to use the manual
tracks mode and manually control the retraction and protraction
of the wheel-sets. Follow scrupulously the paragraph pertaining to
obstacle mounting in manual tracks mode.
