GROUNDING INSTRUCTIONS:
DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with
or for Invacare products. Some devices are equipped with three-prong (grounding) plugs for protection
against possible shock hazards. Where a two-prong wall receptacle is encountered, it is the personal
responsibility and obligation of the customer to contact a qualified electrician and have the two-prong
receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the
National Electrical Code. If you must use an extension cord, use ONLY a three-wire extension cord having
the same or higher electrical rating as the device being connected. In addition, Invacare has placed
RED/ORANGE WARNING TAGS on some equipment. DO NOT remove these tags.
RAIN TEST
INVACARE has tested it’s power wheelchairs in accordance with ISO 7176 Part 9 “Rain Test”. This provides
the end user or his/her assistant sufficient time to remove his/her power wheelchair from a rain storm and
retain wheelchair operation.
DO NOT leave power wheelchair in a rain storm of any kind.
DO NOT use power wheelchair in a shower or leave it in a damp bathroom while taking a shower.
DO NOT leave power wheelchair in a damp area for any length of time.

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. This powered wheelchair model as shipped has an unknown immunity level.
6
GENERAL GUIDELINES
PROCEDURE 1
WARNING
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.
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 controllers for this application have unknown immunity levels.
Modification of any kind to the electronics of this wheelchair as manufactured by Invacare may adversely affect the RFI immunity levels.

SAFETY/HANDLING OF
WHEELCHAIRS
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.
“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.
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. Make sure to use ONLY secure, non-detachable parts for hand-hold supports.
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.
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.
Follow this procedure for moving the wheelchair between floors when an elevator is NOT available:
WARNING
Stability and Balance
The weight of the wheelchair without the user and
batteries is still between 140 and 168 lbs. Use proper
lifting techniques (lift with your legs) to avoid injury.
WARNING
ALWAYS wear your seat positioning strap.
1. Remove the occupant from the wheelchair.
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.
2. Remove the battery boxes from the wheelchair. Refer to INSTALLING/REMOVING BATTERY BOXES
in PROCEDURE 11 of this manual.
Coping With Everyday Obstacles
5. The wheelchair should not be lowered until the last
stair has been negotiated and the wheelchair has
been carried away from the stairway.
3. Bend your knees and keep your back straight.
4. Using non-removable (non-detachable) parts of the
wheelchair, lift the wheelchair off of the ground and
transfer the wheelchair up or down the stairs.
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.
ESCALATORS? SORRY!
DO NOT use an escalator to move a wheelchair
between floors. Serious bodily injury may occur.
A Note to Wheelchair Assistants
When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back
straight and bend your knees whenever tilting wheelchair or traversing curbs, or other impediments.
Also, be aware of detachable parts such as arms or legrests. These must NEVER be used for hand-hold or lifting supports, as they may be inadvertently released, resulting in possible injury to the user and/or assistant(s).
When learning a new assistance technique, have an
experienced assistant help you before attempting it alone.

GENERAL GUIDELINES
PROCEDURE 1
Transferring to and From Other Seats
Percentage of Weight Distribution
WARNING
WARNING
ALWAYS turn the wheelchair power OFF and engage the motor locks/clutches to prevent the
wheels from moving BEFORE attempting to transfer in or out of the wheelchair. Also, make sure
every precaution is taken to reduce the gap distance aligning both rear casters parallel with the
object you are transferring onto.
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.
Many activities require the wheelchair user to reach,
bend and transfer in and out of the wheelchair.
These movements will cause a change to 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.
CAUTION
When transferring, position yourself as far back as
possible in the seat. This will prevent broken screws,
damaged upholstery and the possibility of the
wheelchair tipping forward.
NOTE: This activity may be performed independently
provided you have adequate mobility and upper body
strength.
1. Position the wheelchair as close as possible along
side the seat to which you are transferring, with the
rear casters pointing away from it.
2. Engage motor locks/clutches. Refer to one (1) of the
following.
A. WHEELCHAIRS WITH MOTORS THAT HAVE
CLUTCHES - ENGAGING/DISENGAGING
MOTORS WITH CLUTCHES in PROCEDURE
8 of this manual.
Proper positioning is essential for your safety. When
reaching, leaning, bending or bending forward, it
is important to use the rear casters as a tool to maintain stability and balance.
Functional Reach From a Wheelchair
The approximate reach-limit values shown in the accompanying graphs were derived on the basis of a sample of
91 male and 36 female wheelchair users. Note the difference between the maximum and the comfortable reach
limits, a subjective but important consideration in design.
B. WHEELCHAIRS WITH MOTORS THAT HAVE
MOTOR LOCKS - ENGAGING/DISENGAGING MOTORS WITH MOTOR LOCKS in PROCEDURE 8 of this manual.
3. Shift body weight into seat with transfer.
During independent transfer, little or no seat platform will
be beneath you. Use a transfer board if at all possible.
MINIMIZE GAP

when it is the only cell that doesn’t charge.
When reading a hydrometer, DO NOT allow any
liquid to come in contact with your eyes or skin. It
is a form of acid and can cause serious burns,
and in some cases, blindness. If you do get battery acid on you, flush the exposed areas with
cool water IMMEDIATELY. If the acid comes into
contact with eyes or causes serious burns, get
medical help IMMEDIATELY.
9. Flush hydrometer in cold running water by allowing
the water to rise into the hydrometer as far as possible. Do this several times to guard against burn
damage.
10. Replace the battery caps.
The battery acid can damage your wheelchair,
clothing, and household items. Therefore, take
readings cautiously and only in designated areas.
11. Install the battery boxes onto the wheelchair. Refer
to INSTALLING/REMOVING BATTERY BOXES in
PROCEDURE 11 of this manual.
ONLY use distilled water when topping off the
battery cells.
Most batteries are not sold with instructions. However, warnings are frequently noted on the cell

PROCEDURE 11
WHEN TO CHARGE BATTERIES
(FIGURE 7)
CHARGING BATTERIES (FIGURE 8)
WARNING
It is advantageous to recharge daily rather than only when
necessary. In fact, a battery’s life is extended if the charge
level is maintained well above a low condition.
MKIV RII Joystick
Never attempt to recharge the batteries by attaching cables directly to the battery terminals
or clamps. Always use the recharging plug located on the controller OR the side/rear of the
wheelchair frame.
BATTERY DISCHARGE INDICATOR (BDI) is located at
the front of the joystick housing and provides information
on the remaining charge in the batteries. At FULL charge
the BDI will be GREEN. As the battery becomes discharged,
the BDI indicator will turn AMBER (YELLOW), then RED
and finally FLASHING RED. If the BDI is FLASHING RED,
the user should charge the batteries as soon as possible.
DO NOT attempt to recharge the batteries and
operate the power wheelchair at the same time.
NOTE: Accurate readings are displayed when in neutral.
Always charge new batteries fully BEFORE initial
use or battery life will be reduced.
MCC-MKIV X, A or A+ Joystick
During use and charging, unsealed batteries will
vent hydrogen gas which is explosive in the right
concentration with air.
CAUTION
BATTERY GAUGE DISPLAY (BGD) is the bar graph display located on the MKIV X, A or A+ joystick. It will keep you
informed as to power availability. A visual warning is given
before the power becomes too low to operate the wheelchair.
At full charge the two (2) LEFT segments and the farthest
RIGHT segment of the bar graph will be illuminated. As the
battery becomes discharged, the farthest RIGHT segment
will progressively move to the LEFT until only the last two (2)
bars (LEFT) are illuminated. At this level the last two (2) bars
(LEFT) will start to Flash ON and OFF to indicate that the end
user should charge the batteries as soon as possible.
NOTE: As a general rule, batteries should be recharged
daily to assure the longest possible life and minimize the
required charging time. Plan to recharge the batteries
when it is anticipated the wheelchair will not be used for
several days.
The range per battery charge using recommended batteries should be approximately 5 to 9 hours of typical operation. Extensive use on inclines or age of batteries may
substantially reduce per charge mileage.
NOTE: Accurate readings are displayed when in neutral.
The charger automatically reduces the amount of charge
from an initially high rate to a zero reading at a fully charged
condition.
Description and Use of Battery Chargers
SHUTOFF PROCEDURE.
A. For PRONTOR2 Models - If left unattended, the
charger will automatically shut-off when full charge
is obtained.
Battery Discharge
Indicator (BDI)
B. For PRONTOR2-250 Series Models - The Charger output and green light will stay ON until the power switch
on the battery charger is moved to the OFF position.
MKIV- RII JOYSTICK
There are some basic concepts which will help you
understand this automatic process:
Battery Gauge
Display (BGD)
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. (For PRONTOR2 Models - this is indicated
by the green light on the charger. Initially, the green light
will stay illuminated for a short period of time followed by
a longer period of off time.)
As a charge builds up, the charge rate is reduced, and
the following will occur:
MKIV X, A OR A+ JOYSTICK
A. For PRONTOR2-250 Series Models - the green light
will stay illuminated for a longer period of time
followed by a shorter off time.

NOTE: PRONTOR2 ONLY - If the charger operates for
sixteen (16) hours and is unable to fully charge the batteries, an internal timer turns the charger off and begins to
fast blink the green light.
NOTE: If the batteries need to be charged more often or
take longer to charge than normal, they may need to be
replaced. Contact an authorized dealer for service.
