ELECTROMAGNETIC INTERFERENCE (EMI)
The rapid development of electronics, especially in the area of communications, has saturated our environment with
electromagnetic (EM) radio waves that are emitted by television, radio and communication signals. These EM wave are
invisible and their strength increases as one approach the source. All electrical conductors act as antennas to the EM
signals and, to varying degrees, all power scooters and scooters are susceptible to electromagnetic interference (EMI).
The interference could result in abnormal, unintentional movement and/or erratic control of the vehicle. The United
States Food and drug Administration (FDA) suggests that the following statement be incorporated to the user’s manual
for all power scooter like the S21 TRANSPORT EZ FOLD. Power scooters may as susceptible to electromagnetic
interference (EMI), which is interfering electromagnetic energy emitted from sources such as radio stations, TV stations,
amateur radio (HAN) transmitter, two-way radios, cellular phones and alarm systems of shops. The interference (from
radio wave sources) can cause the power 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 EM energy can be measured in
volts per meter (V/m).Each powered scooter can resist EMI up to a certain intensity. This is called “immunity level”. The
higher the immunity level the greater the protection. At this time, current technology is capable of providing at least 20
V/m of immunity level, which would provide useful protection against common sources of radiated EMI.
Following the warnings listed below should reduce the chance of unintended brake release or powered scooter
movement that could result in serious injury:
1. Do not turn on hand-held personal communication devices such as citizens band (CB) radios and cellular phones
while the powered 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 powered scooter off as soon as it is safe.
4. Be aware that adding accessories or components, or modifying the powered scooter, may make it more susceptible
to interference from radio wave sources (Note: It is difficult to evaluate the effect on the overall immunity of the
powered scooter).
5. Report all incidents of unintended movement or brake release to the powered scooter manufacturer, and note
whether there is a radio wave source nearby.
TURN OFF YOUR POWERED SCOOTER AS SOON AS POSSIBLE WHEN EXPERIENCING THE FOLLOWING:
Unintentional scooter movements
Unintended or uncontrollable direction.
Unexpected brake release
The FDA has written to the manufacturers of power scooters asking them to test new products to be sure they provide a
reasonable degree of immunity against EMI. The FDA requires that a powered scooter should have an immunity level at
least 20 V/m, which provides a reasonable degree of protection against more common sources of EMI. The higher the
immunity level the greater the protection. Your powered scooter has an immunity level of 20 V/m which should protect
against common sources of EMI.
Warning:
The scooter itself can disturb the performance of the electromagnetic fields such as emitted by alarm systems of
shops.
The driving performance of the scooter can be influenced by electro magnetic fileds

operation of this vehicle we recommend that you select a speed that is comfortable for you to control it safely.
The following steps are required to operate your vehicle safely with the controller.
Button functions
1. Battery Indicator: When your scooter is switched on, the needle on the meter will move across the scale
from the left 'red' sector towards the 'green' sector, indicating the state of charge in your batteries. As the
power is used up in your batteries, the needle will slowly towards the 'red' sector indicating the state of
charge at that precise time. When the needle is fully over to the right, the batteries are fully charged.
When the needle falls towards the red sector, your batteries are losing power, but you will still have power
to spare. When the needle falls into the red sector, your batteries are low in power and need to be
recharged. It is wise to recharge your batteries when the needle enters the red zone (see Batteries and
Battery Charging section of this manual).
2. High/Low Speed Adjustment: This allows you to pre-select your desired speed. The adjuster is
proportional to speed and can be set anywhere between minimum and maximum. Turn the adjuster knob
counter-clockwise to minimum for a very gentle operation, and clockwise towards maximum to increase
your speed.

Free-Wheeling:
1. The motors are designed to engage the electromagnetic brakes when the vehicle is not in use or when the
power is OFF. They also have a manual feature that allows them to “free-wheel” so the scooter can be
moved without turning it on. Free-wheeling is accomplished by adjusting the free-wheeling switch to the
free-wheeling position.
2. Engaging in freewheel mode will have the function as parking brake.
Never free-wheel your power scooter on a slope.
Never free-wheel the motors while operating your vehicle.
Always remember to engage the motors before turning the power ON.
PLEASE TURN OFF THE POWER BEFORE FOLDING/UNFOLDING POWER SCOOTER
Electromagnetic Brakes:
Your power scooter comes with Electromagnetic Brakes., i.e. an automatic magnetic disc safety brake which is also known
as Fail-Safe brake. The electro-magnetic Brakes are automatic and work when the power scooter is ON but in a steady
state (i.e. Wigwag is released to the neutral position), even when the scooter is on a slope. The Electromagnetic Brakes
will also be set whenever the power scooter is OFF, but the motor levers are in the engaged (vertical) position.
Parking brake:
There is an automatic parking brake function included in the electromagnetic brake. The scooter will stop when the
motor is engaged and the power switch is off or when the power switch is on and the wigwag is in the neutral position. If
the scooter is in the free wheel mode (motor is disengaged), you can use the manual parking brake function by moving
the engaging/disengaging lever back into the engaged position by an attendant.
Thermal Protection:
Your power scooter controller is equipped with a safety system called thermal rollback. A built-in circuit monitors the
temperature of the controller and motor. In case of excessive heat of the controller and motor, the controller will cut-off
the power to allow the electrical components to cool down. Although your power scooter will resume its normal speed
when the temperature returns to a safe level, we recommend to wait for 5 minutes before restarting to allow the
components to cool down.
Remove the battery box from the power scooter

BATTERY & CHARGING INTRUCTION
We recommend that you use deep-cycle batteries that are sealed and maintenance free for your power scooter.
Depending on the use, terrain and driving conditions, the batteries will provide a range of 15 KM of travel.
However, even if the power scooter is not in use, we recommend that the batteries are charged periodically.
Note: Do not use any automotive batteries. They are not designed to handle a long, deep discharge and also are
unsafe for use in power scooter. The useful life of a battery is quite often a reflection of the care it receives.
DO NOT operate this scooter with depleted batteries since the occupant could be stranded
Please remove the battery package from the scooter unit before long term storage

16
CHARGING INTRUCTIONS
BATTERY CHARGER
The battery charger takes the standard wall outlet voltage (alternating current) and converts it into DC voltage
(direct current).The batteries use direct current to run your power scooter. When the batteries are fully
charged, the amperage from the charger is almost at zero. This is how the charger maintains a charge but does
not overcharge the battery.
Note 1: The batteries cannot be charged if they were discharged to nearly zero voltage.
Note 2: The power scooter meet the requirement of ISO 7176-14:2008 and ISO 7176-21:2003.
Note 3: Only use the battery charger type which was provided by the supplier. The use of any different type of
charger can be hazardous and need the approval of the manufacturer.

MAINTENANCE & REPAIR
Your power scooter is designed for minimal maintenance. However, like any motorized vehicle it requires
routine maintenance. To keep your S21 TRANSPORT EZ FOLD for years of trouble-free operation, we
recommend you follow the following maintenance checks as scheduled.
DAILY CHECKS
1. Visual check on the conditions of tires.
2. Inspect the battery condition meter on the controller to determine if batteries need to be charged.
MONTHLY CHECKS
1. Visually inspect the controller harnesses. Make sure that they are not frayed, cut or have any exposed wires.
SEMI-ANNUAL CHECKS
1. Check the motor brushes. We recommended that your authorized dealer inspect the brushes every six months
or sooner if your power scooter is not operating smoothly. If inspection determines excessive wear on the
brushes, they must be replaced or motor damage will result.
Disposal of Your Power Scooter
Your power scooter must be disposed of according to applicable local and national statutory
regulations. Contact your local waste disposal agency or authorized dealer for information on proper
disposal of power scooter packaging, metal frame components, plastic components, electronics,
batteries, neoprene, silicone, and polyurethane materials.
