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 motorized 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 motorized 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.
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.
There is no easy way to evaluate their effect on the overall immunity of the
motorized scooter.

Warnings
：
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.
