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 elec-
tric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to
your powered wheelchair.

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) This device has been tested to a radiated immunity level of 20 volts per meter.
3) The immunity level of the product is unknown.
Modification of any kind to the electronics of this scooter as manufactured by Invac-
are may adversely affect the EMI immunity levels.

SECTION 3—SAFETY/HANDLING OF POWERED SCOOTERS
SECTION 3—SAFETY/HANDLING OF
POWERED SCOOTERS
“Safety and Handling” of the powered scooter requires the close attention of the user.
This manual points out the most common procedures and techniques involved in the safe
operation and maintenance. It is important to practice and master these safe techniques
until you are comfortable in maneuvering the powered scooter.
Use this information only as a “basic” guide. The techniques that are discussed have been
used successfully by many. Individual 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 obstacles
that they may encounter; however, all warnings and cautions given in this manual MUST
be followed. Techniques in t his manual are a starting point for the new powered scooter
user with “safety” as the most important consideration for all.
Stability and Balance
ꢀ WARNING
DO NOT make sharp turns in the forward or reverse direction at excessive speed.
Failure to observe the warning can cause the scooter to tip over and may result in
injury to user and/ or damage to the product.
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.
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.
Toassurestabilityandproperoperationofyou r powered scooter, you MUST, at all times,
maintain proper balance. Your powered scooter has been designed to remain upright and
stable during normal daily activities.
Many activities require the scooter owner to reach, bend and transfer in and out of the
powered scooter. These movements cause a change to the normal balance, the center of
gravity, and the weight distribution of the powered scooter. 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 scooter. Proper positioning is essential for your safety.

ꢀ 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 make sharp turns in the forward or reverse direction at excessive speed.
Failure to observe the warning can cause the scooter to tip over and may result in
injury to user and/ or damage to the product.
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 powered scooter.
Ensure seat is properly locked before attempting transfer into or out of the
powered scooter. Attempting unsafe transfers may cause a fall from the powered
scooter resulting in bodily injury.
For individuals with balance problems, practice transferring activities with an
assistant in the presence of a qualified healthcare professional. DO NOT attempt to
transfer into or out of the powered scooter without assistance.
4. Transferring to and from the seat c an be accomplished in one of two ways:
• Flipping up the armrest makes entering/exiting easier.
5. Once you have transferred into the seat, rotate seat to the forward position and flip
arms down.

SECTION 6—OPERATION OF THE POWERED SCOOTER
7. Adjust speed control knob to the appropriate setting.
NOTE: For driving indoors or on uneven terrain, a slower speed is recommended. For soft terrain
or steep inclines (no greater than 8°), a faster speed may be necessary.
8. Insert the key into the ignition and turn it to the on position.
ꢀ WARNING
ALWAYS depress the throttle control lever gradually. This will ensure smooth safe
starts.
NOTE: Throttle control levers operate such that moving one will also move the opposite side
throttle control lever.
9. To operate the scooter, depress the thr ottle control lever in the following manner:
• To Move Forward - Push th e right side throttle control lever (away from the user)
or pull the left side throttle control lever towards the user).
• To Move in Reverse - Push the left side thr ottle control lever (away from the user)
or pull the right side throttle control lever (towards the user).
• To Stop - Release the throttle control lever and the powered scooter will quickly
slow down and the brake will engage.
NOTE: To equip the scooter for left hand operation, contact a qualified technician.
The powered scooter is equipped with a "proportional" control meaning that the farther
you depress the throttle control lever, the faster the powered scooter travels. With a
proportional control, you can drive as slowly in the high speed setting as you can in the
low speed setting. Your top speed, however, is limited by the setting of the speed-control
knob. For safety reasons, reverse speed is limited to approximately 50% of forward speed.
When first learning to drive, adjust speed control knob for a slow speed and try to drive
the powered scooter as slowly as possible by depressing the throttle control lever only
slightly. This exercise will help you learn to utilize the full potential of the proportional
control and allow you to start and stop smoothly.
