EMC (EMI) WARNINGS
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF ELECTRO MAGNETIC CONTAMINATION, (EMC) ON YOUR MOBILITY SCOOTER. SOMETIMES THIS EFFECT IS ALSO KNOWN AS ELECTRO MAGNETIC INTERFERENCE, (EMI).
EMC, (EMI), FROM RADIO-WAVE SOURCES.
Mobility scooters may be susceptible to EMC, which is interference from electromagnetic energy, (EM), emitted from sources such as radio stations, TV stations, amateur (HAM) radio transmitters, two way radios and mobile phones. The interference, (from radio sources), can cause the mobility scooter to release it’s brakes, move by itself, or move in an unintended way. Permanent damage can also be done to the mobility scooters control system.
The intensity of the interfering EM energy can be measured in volts per meter, (V/m.).
Each mobility scooter can resist EMC up to a certain intensity. This is known as the scooters “immunity level”.
The higher the immunity level, the greater the protection.
Current technology offers useful protection of at least 20 V/m. which provides protection from the more common sources of radiated EMC.
There are a number of relatively strong electromagnetic fields present in the everyday environment. Most of these sources are obvious and easy to avoid, others are not so obvious and can be unavoidable.
By following the warnings listed, your risk of exposure to EMC will be minimised.
EMC sources can be broadly classified into three types;
1.
2.Medium range mobile transmitters such as those used on emergency services vehicles, taxis etc. These usually have antennas mounted on the outside of the vehicle.
