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 IF YOU EXPERIENCE
THE FOLLOWING:
Unintentional scooter movements
Unintended or uncontrollable
direction.
Unexpected brake release
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 an
alarm system

capabilities.

DeVilbiss
recommends
that
you
perform a safety check before each use to
make sure your scooter operates safely.
Inspections prior to using your scooter:
1.
If equipped with pneumatic tyres, please
check for the tyres are not flat.
2.
Please check all electrical connections and
make sure they are tight and not corroded.
3.
Please check all harness connections and
make sure they are secured properly.
4.
Please check the brakes.
Weight limitation.
1.
Do not exceed the weight capacity stated in
the Specification section. Exceeding the
weight capacity voids your warranty. Drive
DeVilbiss
will
not
be
held
responsible
for
injuries
or property damage resulting from failure
to observe weight limitations.
2.
Do not carry passengers on scooters.
Carrying passengers on your scooter may
affect the centre of gravity, resulting in a tip
or a fall.
Tyre inflation
1.
If your scooter is equipped with pneumatic
tyres, check the tyre pressure every week.
2.
The correct tyre pressure will prolong the
life of your tyres and ensure a smooth ride.
3.
Do not under-inflate or over-inflate your
tyres. It is critically important that tyre
pressure is maintained between 25 – 30 psi
(2.0 – 2.4 bar).
Temperature
1.
Some of the parts of the scooter are
susceptible to change in temperature. The
controller can only operate in temperature
that ranges between -25ºC ~ 50ºC (-13ºF to
122ºF).
2.
At extreme low temperatures, the batteries
may freeze, and your scooter may not be
able
to
operate.
In
extreme
high
temperatures, it may operate at slower
speeds due to a safety feature of the
controller that prevents damage to the
motors and other electrical components.
ELECTROMAGNETIC
INTERFERENCE
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
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). The interference could result
in abnormal, unintentional movement and/or
erratic control of the vehicle. Scooters may be
susceptible to electromagnetic interference
(EMI), which is interfering electromagnetic
energy emitted from sources such as radio
stations, TV stations, amateur radio (HAM)
transmitters, two-way radios, cellular phones
and alarm systems. The interference (from radio
wave sources) can cause the 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 citiHW007s
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
