MOBILITY SCOOTER ELECTROMAGNETIC INTERFERENCE:

Because EM energy rapidly becomes more intense as one move closer to the transmitting 

antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of special 

concern. It is possible to unintentionally bring high levels of EM energy very close to the 

motorized scooter control system while using these devices. This can affect mobility scooter 

movement and braking. Therefore, the warnings listed below are recommended to prevent 

possible interference with the control system of the mobility scooter.

Warnings:

Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur 
radio (HAM) transmitters, two-way radios, and mobile phones can affect mobility scooters.
Following the warnings listed below should reduce the chance of unintended brake release 
or mobility scooter movement which could result in serious injury. 

1.  Do not operate hand-held transceivers (transmitters-receivers), such as citizens band (CB) 

radios, or turn ON personal communication devices, such as mobile phones, while the 

mobility scooter is turned ON;

2.  Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close 

to them;

3.  If unintended movement or brake release occurs, turn the mobility scooter OFF as soon as it 

is safe;

4.  Be aware that adding accessories or components, or modifying the mobility scooter, may 

make it more susceptible to EMI; and

5.  Report all incidents of unintended movement or brake release to the distributor listed on the 

inside front cover of this manual. Note whether there is a source of EMI nearby.

•  Other types of hand-held devices, such as cordless phones, laptop 

computers, AM/FM radios, TV sets, CD players, 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 mobility scooter.

•  There is no easy way to evaluate their effect on the overall immunity  

of the mobility scooter.

Important Information:

1.  20 volts per meter (V/m) is a generally achievable and useful immunity level against EMI  

(as of May 1994). The higher the level, the greater the protection.

2.  The immunity level of this product is at least 20/Vm.
