Electromagnetic interference

Radio waves can have a negative effect on the capacity of an electric scooter. The
scooter itself can also interfere with the operation of electromagnetic fields, such as
alarm systems or electronic circuits in shops.
Powered wheelchairs and scooters can be affected by sources of radio waves, such as
radio and TV transmitters, amateur radio stations, lifts, transmitting equipment, stereo
radios and mobile telephones.
The following advices are intended to prevent the electric scooter from being driven
unintentionally, which could lead to serious injury.
1. Do not turn on any manually controlled equipment for personal communication,
such as a radio transmitter or mobile telephone, while the electric scooter is
switched on.
2. Keep at a distance from transmitter equipment, such as radio and TV stations.
3. If the scooter starts making unintended movements, or if the brake goes into
neutral, turn off the powered wheelchair or scooter by removing the ignition key
from the lock.
4. Be aware of the fact that any accessories, components or adaptations installed on
the scooter may increase the effect of radio waves.
Remarks:
There is no easy way of testing the effects of radio waves on the general immunity
of powered wheelchairs or scooter.
5. All cases of unintended movements or of the scooter spontaneously going into
neutral should be reported to your dealer or to the scooter manufacturer. When
reporting, please indicate whether a source of radio waves was nearby at the time.
Remarks:
The Fortress Calypso's immunity level is 21 volt/metre.
