WARNING
Defective safety functions
Falling, tipping over, collision with persons or nearby objects due to lack of inspection
► Before every use, ensure that the product and its safety functions are in safe and proper condition.
► Only use the product if all safety functions, e.g. the automatic brakes, are functional.
WARNING
Unexpected emergency stop
Falling, the user may fall out due to sudden emergency braking
► In the event of communication problems in the control device bus system or a power supply defect, the sys­
tem triggers an emergency stop and thus avoids uncontrolled functions.
► Note that this emergency stop in road traffic could lead to situations that are hazardous for you. Ensure that
the control device is maintained regularly (see page 41).
► Note that after every emergency stop, you have to turn the power wheelchair control device on again.
► If the driving function is still not available after turning the control device on again, pushing mode can be activ­
ated by releasing the brake (see page 24).
► Consult the qualified personnel promptly if the driving function is not available after restarting.
INFORMATION
In dangerous situations, the product can be turned off at any time using the on/off button. The power wheelchair
stops immediately when the button is pressed. Malfunctions such as an insufficient supply of power to the control
device are recognised by the software, triggering an emergency stop or reducing the speed of the product.
• Pressing the [on/off] button (see page 16) turns the power wheelchair control unit on or off. The power wheel­
chair turns off automatically if the control unit has not been used for an extended period of time.
• The power wheelchair brakes automatically and comes to a stop if it is turned off with the [on/off] button while
being driven.
• Each time you switch on the control unit, it will be at the previously selected speed level.

7.7.4 Selecting the speed levels

• The control device on the power wheelchair has five speed levels.
• Pressing the [Decrease speed] button lowers the speed level.
• Pressing the [Increase speed] button increases the speed level.
• The pitch of the audible signal changes once the highest or lowest speed level is reached.
• The [Selected speed level] LED display shows the speed level selected.
• Qualified personnel can replace the speed levels with up to five individual driving profiles and adjust the para­
meters in each driving profile (e.g. acceleration and speed values).
