2.4.1 ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO 

WAVE SOURCES 

 

Powered scooters may be susceptible to electromagnetic interference (EMI), which is interfering 

electromagnetic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) 

transmitters, two-way radios, and mobile phones. The interference (from radio wave sources) can cause the 

powered scooter to release its brakes, move by itself, or move in unintended directions. It can also 
permanently damage the powered scooter’s control system. The intensity of the interfering EM energy can be 
measured in volts per metre (V/m). Each powered scooter can resist EMI up to a certain intensity. This is 
called its “immunity level”. The higher the immunity level, the greater the protection. At this time, current 
technology is capable of achieving at least a 20 V/m immunity level, which would provide useful protection 

from the more common sources of radiated EMI. This powered scooter model as shipped, with no further 

modification, has an immunity level of 20 V/m without any accessories. 

 

There are a number of sources of relatively intense electromagnetic fields in the everyday environment. 

Some of these sources are obvious and easy to avoid. Others are not apparent and exposure is unavoidable. 

 

However, we believe that by following the warning listed below, your risk to EMI will be minimized.The 

sources of radiated EMI can be broadly classified into three types: 

 

1. Hand-held portable transceivers (transmitter-receivers with the antenna mounted directly on the 

transmitting unit). Examples include: citizens band (CB) radios, “walkie talkies”, security, fire, and police 

transceivers, mobile telephones and other personal communication devices. 

 

 

Attention

 

Some mobile telephones and similar devices transmit signals while they are ON, even 

when not being used. 

 

2. Medium-range mobile transceivers, such as those used in police cars, fire trucks, ambulances and 

taxis. These usually have the antenna mounted on the outside of the vehicle. 

3. Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio and TV 

broadcast antenna towers) and amateur (HAM) radios. 

   

 

Attention

 

Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM 

radios, TV sets, CD player, and cassette players, and small appliances, such as electric 

shavers and hair dryers, so far as we know, are not likely to cause EMI problems to your 

scooter. 

 

2.4.2 POWERED SCOOTER ELECTROMAGNETIC INTERFERENCE 

(EMI) 

Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source),
