removing or installing the batteries, use hoisting devices of sufficient capacity or complete these tasks
with the support of a helper.

INfORMATION
The power wheelchair has been tested according to EMC regulations. The following particularities
must be observed when using the wheelchair:
• The driving characteristics of the power wheelchair can be affected by electromagnetic fields (mo-
bile phones or other radiating devices). Therefore all mobile devices must be turned off when driving.
• The power wheelchair can generate electromagnetic fields that can cause interference with other
devices. Therefore, turn off the control unit whenever you do not need it.
