ELECTROMAGNETIC INTERFERENCE AND WARNINGS
2
CAUTION: It is very important that you read this information regarding the possible
effects of Electromagnetic Interference on your power chair.
Powered wheelchairs and motorized scooters may be susceptible to electromagnetic
interference (EMI), which is interfering electromagnetic energy (EM) 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 power
chair to release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the power chair control system. The intensity of the interfering
EM energy can be measured in volts per meter (V/m). Each power chair can resist EMI
up to a certain intensity. This is called its "immunity level." The higher the immunity level,
the greater the protection will be. 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. The immunity level of this product 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.
Some cellular telephones and similar devices transmit signals while
they are ON, even when not being used.
Electromagnetic Interference and Warnings：
The sources of radiated EMI can be broadly classified into three types:
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.
3.Long-range transmitters and transceivers such as commercial broadcast transmitters
(radio and TV broadcast antenna towers) and amateur (HAM) radios.
Because EM energy rapidly becomes more intense as one moves 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 power chair control system while using these devices. This can affect power chair
movement and braking. Therefore, the warnings listed below are recommended to prevent
possible interference with the control system of the power chair.
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 power chair.
Power Chair Electromagnetic Interference：
Warnings
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur
radio (HAM) transmitters, two-way radios, and cellular phones can affect the power chair.
Following the warnings listed below should reduce the chance of unintended brake release
or power chair movement, which could result in serious injury.
Electromagnetic Interference and Warnings：
User ManualEW-M47
3
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 power chair 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 power chair OFF as soon
as it is safe;
4.Be aware that adding accessories or components, or modifying the power chair, 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.
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.
IMPORTANT PRECAUTIONS
Safety is the main consideration when practicing with your chair. It is required that you
read and comprehend all the operating and safety instructions discussed in this manual.
And ensure your chair is correctly fitted and adjusted by your dealer or the prescribing
healthcare professional.
Make sure to engage the wheel locks before entering or leaving the chair. The wheel locks
are designed to prevent movement of the chair. It is preferable to ensure the front castors
are in the forward position before transferring in to or out of the chair. With the castors
in the forward position the wheel base of the chair is increased and therefore, offers more
stability.
DO NOT move forward in the seat while leaning forward out of the chair. If an object is
to be picked up from the floor, drive past it, then reverse so the front castors are in the
forward position. This gives the chair its greatest stability.
To maintain lateral stability do not reach further than the length of your arm. DO NOT
lean out of the chair as this could cause instability.
When transferring, DO NOT stand on the leg rests. Depending on the style of leg rests
either swing them away or fold them up before transferring.
When approaching a ramp, be sure of your own ability and your limitations in terms of
strength and endurance.
Before attempting a ramp the following basic safety rules should be considered：
1.Surface of the ramp: Is it too slippery?
2.Degree of incline: Is it too steep to attempt alone?
3.Length of ramp: Is it too long for your endurance?
4.Obstacles: Are there any obstacles on the ramp that would necessitate assistance?
User ManualEW-M47
Please be aware that any adjustments on the power chair may affect the
handling and performance.

Be very careful when going up or down steep inclines
If it becomes necessary to stop when going up an incline, special care must be taken to
avoid abrupt or sudden forward movement. During continuous forward movements, the
chair is capable of falling backwards.
Always keep the chair under control when going down a ramp or incline. Speed should
be controlled at all times.
The user in the power chair and a curb is encountered, caution should be taken to prevent
the user being thrown forward:
Do not try to climb a curb by driving up it. Have a helper move the chair for you following
the instructions below.
1.With both motors disengaged, go down the curb, rear wheels first; making sure that
the user is square to the curb so that the rear wheels go down together.
2.To go up a curb forward, verify both front wheels are up together. This must be
accomplished with the motors disengaged.
Also try to avoid going up multiple steps and using escalators. Use the elevator instead.
User ManualEW-M47
1.Please read the instruction Booklet carefully before using your scooter.
2.Keep the scooter properly maintained.

BATTERIES AND CHARGING
18
When your batteries are fully charged you should have sufficient power to give you all
the mobility required in a day. It is important that you understand how your batteries and
charger work. Batteries must be charged before using the power chair for the first time
and are recommended to be charged up to 10 - 14 hours after each day's use.
Maintain the Batteries :
1. Batteries should be charged every night in a well ventilated room.
2. DO NOT place the power wheelchair near radiators or open fireplaces while charging.
3. DO NOT smoke or permit open flames in the immediate vicinity.
4. Turn the chair controller power off before charging.
5.
It is advisable that the batteries be charged for a minimum of 10 hours per night to ensure
full battery storage capacity. The battery charger is an automatic current limiting device
and will shut off when the batteries are fully charged.
Charging the batteries :
1. Position power chair next to a standard wall outlet.
2. Connect the battery charger to the wheelchair input battery charging socket, which is
located on the front of the controller.
3. Connect the battery charger to a standard wall power outlet.
4. Switch the power on.
During the recharge :
While the batteries are being recharged, a red light will appear on the battery charger,
indicating that the power is connected and charging is in progress.
At the end of the recharge cycle:
1. A green light will appear on the charger. This indicates that the batteries are fully
charged and ready for use.
2.
If fitted, the battery charge level indicator on the controller should also show a full charge
when switched on.
When do the batteries need charging?
When the batteries fall below 20% of its maximum charge level, the series of lights on
the controller will flash.
1. Do not use batteries other than the recommended type for your chair and
never use a charger other than the one supplied for that purpose.
2.
If the chair is not used for a long period of time arrange to have the batteries
charged for at least one day (10-14 hours) every month, minimum.
3.
Periodically, check that the battery terminals are clean and the connections
are tight. Smear a thin film of petroleum jelly on the terminals to guard
against corrosion. Always wash your hands after handling batteries.
