E Practice Before Operating
Find an open area such as a park and have an assistant to help you practice until you
have confidence operating this vehicle.
Make sure that the power is off before AT
getting in or out of the seat. Set the N iQ
speed control button according to your a LL | | =
driving ability. <A !
We recommend that you keep the
speed control at the slowest
position until you are familiar with
the driving characteristics of this
Stop, forward, and reverse operation practice
Pull the lever forward on the
right side to move forward
Pull the lever forward on the backward
left side to move backward
Getting familiar with this vehicle
First, practice moving forward.
Be sure to set the speed to the lowest setting.
After becoming familiar with moving forward,
practice mark "S" turns.
Once you are familiar with "S" turns, practice
moving in reverse.
u Safety Considerations
DO NOT do any of the following
Do not drink and drive Do not tow a trailer
Consult your physician to determine
if your medications impair your ability
to control this vehicle
Do not turn on or use hand-held persona
communication devices such as citizens band(CB)
radios and cellular phones
This vehicle has an immunity level of 20 V/m which should protect it from
Electromagnetic Interference(EMI) from Radio Wave Sources. The rapid
development of electronics, especially in the area of communications, has
saturated our environment with electromagnetic (radio) waves that are emitted
by television, radio and communication signals. These EM waves are invisible
and their strength increases as one approaches the source. All electrical conductors
act as antennas to the EM signals and, to varying degrees, all power wheelchairs
and scooters are susceptible to electromagnetic interference (EMI). This interference
could result in abnormal, unintentional movement and/or erratic control of the
vehicle. The United Statement be incorporated to the user's manual for all electric
Powered wheelchairs and electric scooters(in this text, both will be referred to
as powered wheelchairs) may be susceptible to electomagnetic interference(EMI),
which is interfering electromagnetic energy emitted from sources such as radio
stations, TV stations, amateur radio (HAM) transmitters, two-way radios and
cellular phones. The interference (from radio wave sources) can cause the
powered wheelchair to release its brakes, move by itself or move in unintended
directions. It can also permanently damage the powered wheelchair's control
system. The intensity of the EM energy can be measured in volts per meter
(V/m). Each powered wheelchair can resist EMI up to a certain intensity. This
Is called the "immunity level." The highedr 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 wheelchair movement that could result in serious injury:
1) Do not turn on hand-held personal communucation devices such as citizens
band (CB) radios and cellular phones while the powered wheelchair 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 wheelchair
off as soon as it is safe.
4) Be aware that adding accessories or components, or modifying the powered
wheelchair, may make it more sasceptible to interference from radio wave
sources. (Note: there is no easy way to evaluate their effect on the overall
immunity of the powered wheelchair).
5) Report all incidents of unintended movement or brake release to the powered
wheelchair manufacturer, and note whether there is a radio wave source
1. Unintentional motions.
2. Unintended of uncontrollable direction.
3. Unexpected brake release.
The FDA has written to the manufacturers of power wheelchairs, asking them
to test their new products to be sure they provide a reasonable degree of
immunity against EMI. The letter says that powered wheelchair should have
an immunitylevel of at least 20 V/m, which provide a reasonable degree of
protection against the more common sources of EMI. The higher the level,
the greater the protection.
E Driving Outdoors
When you are on the road, please pay attention to the following:
Do not drive in traffic.
If possible, do not drive
during the rain.
Do not drive off-road or on
any uneven surfaced roads.
Do not drive beside a river,
port, or lake without a fence
or railing.
If possible, do not drive
during or on snow.
If possible, do not drive at
| Сар greater 4"(10cm)
Make sure that there are no obstacles behind you
when in reverse.
We recommend to set up the speed knob at the lowest
speed for reversing.
Do not make sudden stops, weave erratically, or
make sharp turns.
Keep your arms on or inside the armrests and feet
on the footrest at all time.
Do not attempt to climb curbs greater that 2"(5cm).
Do not attempt to cross over a gap greater that
® Use caution when driving on hills
Driving on hills is more dangerous than on level surfaces. If you fail
to heed these warnings, a fall, tip-over or loss of control may occur
and cause severe injury to the vehicle user or others.
Do not attempt to climb a hill greater than 10°
10° and |
Do not reverse while driving up a hill.
Forward only. If you reverse while moving up a hill, it
may cause the vehicle to tip over.
y NO!
Do not attempt to drive across a sloping surface
greater that 3°
Driving across a slope greater than 3" is very dangerous
and may cause the vehicle to tip over.
Use caution when driving over soft, uneven or
unprotected surfaces such as grass, gravel and
Use low speed while driving down hill.
When going down hill, the tiller will become harder to
reach and handle. When braking while moving down
hill, the scooter will take longer to come to a complete
Do not get in and off on a hill.
Always stop on the level surface to get in and get out
of the vehicle.
Always climb or descend gradients perpendicular
to the slope or ramp.
Do not load or carry heavy items iin the basket
while driving down hill.
In this section, we will acquaint you with the many features of your scooter and
how they work. Upon rceipt of your scooter, inspect it for any damage. Your
