SECTION 2—EMI INFORMATION
SECTION 2—EMI INFORMATION
WARNING
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION
REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC
INTERFERENCE ON YOUR POWERED WHEELCHAIR.
Electromagnetic Interference (EMI) From Radio Wave Sources
Powered wheelchairs and motorized scooters (in this text, both will be referred to
as powered wheelchairs) 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 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 interfering 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 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.
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.
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).
NOTE: Some cellular telephones and similar devices transmit signals while they are ON,
even when not being used.
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.
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers,
AM/FM radios, TV sets, CD players, 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 powered wheelchair.
At’m 16 Part No. 1125035
Page 17
SECTION 2—EMI INFORMATION
WARNING
Powered Wheelchair Electromagnetic Interference (EMI)
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 powered wheelchair's control system while
using these devices. This can affect powered wheelchair movement and braking.
Therefore, the warnings listed below are recommended to prevent possible
interference with the control system of the powered wheelchair.
Electromagnetic interference (EMI) from sources such as radio and TV stations,
amateur radio (HAM) transmitters, two-way radios, and cellular phones can affect
powered wheelchairs and motorized scooters.
FOLLOWING THE WARNINGS LISTED BELOW SHOULD REDUCE THE
CHANCE OF UNINTENDED BRAKE RELEASE OR POWERED WHEELCHAIR
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 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 susceptible to EMI (NOTE: There is no easy way
to evaluate their effect on the overall immunity of the powered wheelchair); and
5) Report all incidents of unintended movement or brake release to the powered
wheelchair manufacturer, and 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 unknown.
Modification of any kind to the electronics of this wheelchair as manufactured by
Invacare may adversely affect the RFI immunity levels.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
SECTION 3—SAFETY/HANDLING OF
WHEELCHAIRS
“Safety and Handling” of the wheelchair requires the close attention of the wheelchair
user as well as the assistant. This manual points out the most common procedures and
techniques involved in the safe operation and maintenance of the wheelchair. It is
important to practice and master these safe techniques until you are comfortable in
maneuvering around the frequently encountered architectural barriers.
Use this information only as a “basic” guide. The techniques that are discussed on the
following pages have been used successfully by many.
Individual wheelchair users often develop skills to deal with daily living activities that
may differ from those described in this manual. Invacare recognizes and encourages each
individual to try what works best for him/her in overcoming architectural obstacles that
they may encounter, however ALL WARNINGS and CAUTIONS given in this manual
MUST be followed. Techniques in this manual are a starting point for the new wheelchair
user and assistant with “safety” as the most important consideration for all.
STABILITY AND BALANCE
WARNING
ALWAYS wear your seat positioning strap.
The seat positioning strap is a positioning belt ONLY. It is not designed for use as a
safety device withstanding high stress loads such as auto or aircraft safety belts. If
signs of wear appear, belt MUST be replaced immediately.
To assure stability and proper operation of your wheelchair, you must at all times
maintain proper balance. Your wheelchair has been designed to remain upright and
stable during normal daily activities as long as you do not move beyond the center of
gravity. DO NOT lean forward out of the wheelchair any further than the length of the
armrests.
COPING WITH EVERYDAY OBSTACLES
Coping with the irritation of everyday obstacles can be alleviated somewhat by learning
how to manage your wheelchair. Keep in mind your center of gravity to maintain stability
and balance.

Page 19
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
A NOTE TO WHEELCHAIR ASSISTANTS
WARNING
DO NOT attempt to lift the wheelchair by any removable (detachable) parts. Lifting by means of removable (detachable) parts of the wheelchair may result in injury
to the user and/or damage to the wheelchair.
When assistance to the wheelchair user is required, remember to use good body
mechanics. Keep your back straight and bend your knees whenever tipping the
wheelchair or traversing curbs or other impediments.
When learning a new assistance technique, have an experienced assistant help you before
attempting it alone.
LIFTING/STAIRWAYS
WARNING
DO NOT attempt to move an occupied power wheelchair between floors using a
stairway. Use an elevator to move an occupied power wheelchair between floors. If
moving a power wheelchair between floors by means of a stairway, the occupant
MUST be removed and transported independently of the power wheelchair.
Extreme caution is advised when it is necessary to move an unoccupied power
wheelchair up or down the stairs. Invacare recommends using two (2) assistants and
making thorough preparations.
DO NOT attempt to lift the wheelchair by any removable (detachable) parts.
Lifting by means of any removable (detachable) parts of a wheelchair may result in
injury to the user or damage to the wheelchair.
The weight of the wheelchair without the user is approximately 74 lbs. Use proper
lifting techniques (lift with your legs) to avoid injury.
Follow this procedure for moving the wheelchair between floors when an elevator is NOT
available or lifting the wheelchair is necessary:
NOTE: When using a stairway to move the wheelchair, seat and any accessories, move all
wheelchair components away from the stairway prior to reassembly.
1. Remove the occupant from the wheelchair.
2. Transfer the wheelchair to the desired location. Refer to Transporting the Wheelchair
on page 43.
WARNING
DO NOT use an escalator to move a wheelchair between floors. Serious bodily
injury may occur.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
PERCENTAGE OF WEIGHT DISTRIBUTION
WARNING
DO NOT attempt to reach objects if you have to move forward in the seat or pick
them up from the floor by reaching down between your knees.
Proper positioning is essential for your safety. When reaching, leaning, bending or
bending forward, it is important to use the casters as a tool to maintain stability and
balance.
Many activities require the wheelchair user to reach, bend and transfer in and out of
the wheelchair. These movements will cause a change to the normal balance, center of gravity, and weight distribution of the wheelchair. To determine and establish
your particular safety limits, practice bending, reaching and transferring activities in
several combinations in the presence of a qualified healthcare professional BEFORE
attempting active use of the wheelchair.
REACHING, LEANING AND BENDING - FORWARD
WARNING
DO NOT attempt to reach objects if
you have to move forward in the seat or
pick them up from the floor by reaching
down between your knees.
NOTE: For this procedure, refer to FIGURE
3.1.
Position the front casters so that they are
extended as far forward as possible and
engage motor release levers.
FIGURE 3.1F - REACHING, LEANING
AND BENDING - FORWARD
REACHING AND BENDING - BACKWARD
WARNING
DO NOT lean over the top of the back
upholstery. This will change your center
of gravity and may cause you to tip over.
NOTE: For this procedure, refer to FIGURE
3.2.
Position wheelchair as close as possible to
the desired object. Point the front casters
rearward to create the longest possible
wheelbase. Reach back only as far as your
arm will extend without changing your

WARNING
After ANY adjustments, repair or service and BEFORE use, make sure that all
attaching hardware is tightened securely - otherwise injury or damage may result.
DO NOT USE YOUR WHEELCHAIR UNLESS IT HAS THE PROPER TIRE
PRESSURE (P.S.I.) - OTHERWISE THE WHEELCHAIR MAY NOT DRIVE
CORRECTLY, STOP CORRECTLY OR MAY EXPERIENCE ERRATIC
PERFORMANCE.
DO NOT overinflate the tires. Failure to follow these suggestions may cause the
tire to explode and cause bodily harm. The recommended tire pressure is listed on
the side wall of the tire.
Set-up/programming of the Electronic Control Unit is to be performed ONLY by a
qualified technician. The fine tuning adjustments of the controller may affect other
activities of the wheelchair. Damage to the equipment could occur under these circumstances. IF UNQUALIFIED INDIVIDUALS PERFORM ANY WORK ON
THESE UNITS, THE WARRANTY IS VOID.
OPERATING THE WHEELCHAIR
NOTE: For this procedure, refer to FIGURE 5.1.
TURNING THE POWER ON/OFF
1. To turn the power on, press the on/off button.
NOTE: After turning power on, all indicators will light briefly and the display gauge will indicate
one of the following:
A. The Current Battery Charge - Information gauge shows all LED's lit or partial LED's lit.

occurs when the power is turned on when the joystick is out of neutral. This feature
prevents sudden and unexpected movements of the power chair.
2. To turn the power off, press the on/off button again.
USING THE JOYSTICK TO DRIVE THE CHAIR
The joystick is located at the front of the joystick housing and provides smooth control of
speed and direction. It is equipped with 360 degrees of mobility for ease of operation. The
joystick is spring-loaded, and automatically returns to the upright (neutral) position
when released. Pushing the joystick in a given direction causes the chair to move in that
direction.
At’m 24 Part No. 1125035
Page 25
SECTION 5—WHEELCHAIR OPERATION
The joystick has proportional drive control, meaning that the further it is pushed from the
upright (neutral) position, the faster the wheelchair moves. The maximum speed,
however, is limited by the setting of the speed-control knob.
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has
automatic speed and direction compensation to minimize corrections.
When first learning to drive, select a SLOW speed and try to drive the wheelchair AS
SLOWLY as possible by pushing the joystick slightly forward. This exercise will help you
learn to utilize the full potential of the proportional control and allow you to start and
stop smoothly.
To drive the wheelchair, perform the following:
1. Adjust speed control switch to the appropriate setting.
2. Turn the power on. Refer to Turning the Power On/Off
on page 24.
3. Move the joystick in the following manner:

Page 38
SECTION 8—BATTERIES
Basic concepts which will help you understand this automatic process are:
The amount of electrical current drawn within a given time to charge a battery is called
“charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is
high. As a charge builds up, the charge rate is reduced, and the battery charger rate
decreases to a “trickle charge”.
NOTE: If the batteries need to be charged more often or take longer to charge than normal, they
may need to be replaced. Contact a qualified technician.
CHARGING USING AN INDEPENDENT CHARGER PLUGGED INTO THE JOYSTICK
