SAFETY INFORMATION ON
ELECTROMAGNETIC INTERFERENCE (EMI)
CAUTION : It is very important that you read this information regarding the possible
effects of Electromagnetic Interference on your motorized scooter.
Powered wheelchairs and motorized scooters may be susceptible to electromagnetic
interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources
such a radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios,
and cellular phones. The interference (from radio wave sources) can cause the motorized
scooter to release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the motorized scooter control system. The intensity of the interfering
EM energy can be measured in volts per meter (V/m). Each motorized scooter can resist
EMI up to 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 immunity level of this motorized scooter model
is 20 V/m.
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 warnings listed
below, your risk to EMI will be minimized.
1.Hand-held portable transceivers (transmitters-receivers) with the antenna mounted
directly on the transmitting unit. Examples include: citizens band (CB) radios, "walkie
talkie," security, fire, and police transceivers, cellular telephones, and other personal
communication devices;
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; and
3.Long-range transmitters and transceivers such as commercial broadcast transmitters
(radio and TV broadcast antenna towers) and amateur (HAM) radios.
The sources of radiated EMI can be broadly classified into three types :
Some cellular telephones and similar devices transmit signals while they
are ON, even when not being used.
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 motorized
scooter.

Instruction BookletEW-M40•EW-M39
There is no easy way to evaluate their effect on the overall immunity
of the motorized scooter.

Motorized 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 motorized
scooter movement and braking. Therefore, the warnings listed below are recommended to
prevent possible interference with the control system of the motorized scooter.
Warnings :
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur
radio (HAM) transmitters, two-way radios, and cellular phones can affect motorized 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 cellular phones, while
the motorized 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 motorized scooter,
may make it more susceptible to EMI; and
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 20 V/m.
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.

Keep in mind these rules：
•Fully charge batteries at least once a month, or more if you use scooter regularly.
Charge after each trip exceeding 3 kilometers.
•If storing your scooter for some time (1 month or more), make sure that batteries are
fully charged, and on returning, charge them again before using scooter.
•
Batteries will only give maximum performance after scooter has been used, and batteries
have been recharged up to 10 times. A bit like breaking in a new car.
Please be aware that the travelling range of your mobility scooter is impacted by how fast the batteries
are discharged. This will depend on many circumstances, such as ambient temperature, condition of the
surface of the road, tyre pressure, weight of the driver, driving environment (inclines etc.) and utilisation
of your lighting system if fitted. We recommend that you test your local ride with a family member to
ensure a safe journey.
The time needed to recharge will vary depending on the depletion of the
batteries. Charging for longer than necessary will not harm the batteries.
They can not be overcharged.
