WHEELCHAIR USER  
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of  
wheelchairs to meet many needs of the end user. However, final selection of the  
type of wheelchair to be used by an individual rests solely with the user and his/her  
healthcare professional capable of making such a selection. Invacare highly  
recommends working with a certified rehab technology supplier and/or a member  
of NRRTS or RESNA.  
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS (TRBKTS)  
TRBKTS includes four factory-installed wheelchair transport brackets. TRBKTS has  
not been crash-tested in accordance with WC 19. Use these transport brackets only  
to secure an unoccupied wheelchair during transport.  
As of this date, the Department of Transportation has not approved any tie-down  
systems for transportation of a user while in a wheelchair, in a moving vehicle of any  
type. It is Invacare’s position that users of wheelchairs should be transferred into  
appropriate seating in vehicles for transportation and use be made of the restraints  
made available by the auto industry. Invacare cannot and does not recommend any  
wheelchair transportation systems.  
TRBKTS WARNINGS  
Only use the transport brackets included with TRBKTS for the purposes described  
in this manual.

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 metre (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. Also, the electronics used in our  
powered wheelchair can generate a low level of electromagnetic interference,  
which however will remain within the tolerances permitted by law.  
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 wheelchair as manufactured by  
Invacare may adversely affect the EMI immunity levels.

SECTION 5—WHEELCHAIR OPERATION  
SECTION 5—WHEELCHAIR  
OPERATION  
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.  
Set-up of the Electronic Control Unit is to be performed only by a qualified  
technician. The final adjustments of the controller may affect other activities of the  
wheelchair. Damage to the equipment could occur under these circumstances.  
A Note About Drive Lock-Out  
WARNING  
NEVER operate the wheelchair or elevate/lower the seat while the back is in any  
tilted/reclined/back angle position over 20° relative to the vertical position. If the  
drive lock-out does not stop the wheelchair from operating or the seat from  
elevating/lowering in a tilt/recline/back angle position over 20° relative to the  
vertical position, DO NOT operate the wheelchair or elevate/lower the seat. DO  
NOT attempt to adjust the drive lock-out. Have the wheelchair serviced by a  
qualified technician.  
The wheelchair user MUST have a clear line of sight to drive safely. On initial chair  
delivery and after adjusting the back angle, drive lock-out switch, tilt system or  
recline system, tilt and recline the seat back to the farthest driving position  
immediately before drive lock-out engages and ensure there is a clear line of sight  
present in which to drive the wheelchair. If a clear line of sight is not present, have  
the back angle repositioned or readjust the lockout angle such that safe driving with  
a clear line of sight is achieved. Otherwise injury or damage may occur.  
TILT WARNING or SPM Inhibited displays on the joystick or display unit when  
the drive lock-out feature has been activated.  
Drive lock-out is a feature designed to prevent the wheelchair from being driven after the  
seating system has been tilted or reclined beyond 20°* relative to the vertical position. The  
back can be positioned at a 10° relative offset to the seat base, thereby resulting in a back  
angle potential of 30° before which the drive lock-out is activated. This may affect the  
wheelchair users line of sight while driving. Make sure the wheelchair user can see  
properly to ensure safe driving.  
*NOTE: 20° back angle can be any combination of recline, tilt, back angle and/or surface angle.

GENERAL WARNINGS  
procedure.  
Pinch points may occur when returning the seat from any tilted position to the full  
upright position or when lowering the elevating seat. Make sure the hands and body  
of both the occupant and attendants/bystanders are clear of all pinch points before  
returning the seat to the full upright position or lowering the elevating seat.  
NEVER operate the wheelchair or elevate/lower the seat while the back is in any  
tilted/reclined/back angle position over 20° relative to the vertical position. If the  
drive lock-out does not stop the wheelchair from operating or the seat from  
elevating/lowering in a tilt/recline/back angle position over 20° relative to the  
vertical position, DO NOT operate the wheelchair or elevate/lower the seat. DO  
NOT attempt to adjust the drive lock-out. Have the wheelchair serviced by a  
qualified technician.  
Use caution when driving in a tilted, reclined or elevated position.  
DO NOT operate the seating system while on an incline.  
DO NOT operate seating system while the wheelchair is moving.  
DO NOT operate the tilt or elevate function near or under a fixed object such as a  
table or desk.  
The elevating seat option is equipped with a speed reduction safety mechanism.  
While the seat is in an elevated position, the safety feature slows the speed of the  
wheelchair to 20% of its maximum speed (not to exceed the programmed speed). If  
the wheelchair operates at maximum speed while in an elevated position, DO NOT  
operate the wheelchair. Have the wheelchair serviced immediately by a qualified  
technician.  
ACTUATOR CONTROL WARNING  
Use only the actuator controls listed in the following chart to activate the tilt/  
recline/elevate functions. DO NOT USE any other actuator controls. Such devices  
may result in excess heating and cause damage to the actuator and associated  
wiring and could cause a fire, death, physical injury or property damage. If such  
devices are used, Invacare shall not be liable and the limited warranty is void.

SECTION 5—WHEELCHAIR OPERATION  
MPJ+ Joystick Switches and Indicators  
NOTE: For this procedure, refer to FIGURE 5.3.  
Drive Select Toggle Switch  
The drive select toggle switch is located on the left side, below the LCD. The drive select  
position is momentary, meaning that it will return to the neutral position after a selection  
is made.  
This switch allows the operator to select the type of operation or performance which best  
suits a particular control need or situation. The DRIVE 1 program uses performance  
values which are independent of those used for the DRIVE 2 or 3 or 4 program. As an  
example, an operator may have a control need for spasticity in the morning and a very  
different need in the afternoon. DRIVE 1 can be programmed for higher speeds and  
quicker response while DRIVE 2 can be programmed for slower speeds and less  
responsiveness or vise versa. The other two drive programs could be indoor and outdoor  
versions of DRIVE 1 and DRIVE 2.  
Selecting the Drive Mode  
1. Move the toggle up and release. DRIVE 1 ( ) will appear on LCD.  
2. Move the toggle up and release again. DRIVE 2 ( ) will appear on LCD.  
3. Move the toggle up and release again. DRIVE 3 ( ) will appear on LCD.  
4. Move the toggle up and release again. DRIVE 4 ( ) will appear on LCD.

pushed from the upright (neutral) position, the faster the wheelchair or seat moves. Your  
top speed, however, is limited by the programmed settings.  
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has  
automatic speed and direction compensation to minimize corrections.  
Charger/Programming Input  
The charger/programming input is located at the front of the joystick housing. This  
provides easy access for charging the wheelchair batteries. This port also serves as the  
Remote Programmer Communication connection. Driving is prevented while the system  
is charging.

SECTION 10—ELEVATE BATTERIES  
NOTE: This section contains information about batteries in seating systems with elevate. Refer to  
the owner’s manual supplied with the wheelchair base for other battery information.  
Warnings for Handling and Replacing Batteries  
WARNING  
Make sure power to the wheelchair is OFF before performing these procedures.  
The use of rubber gloves is recommended when working with batteries.  
Invacare strongly recommends that battery installation and battery replacement  
always be done by a qualified technician.  
After ANY adjustments, repair or service and BEFORE use, make sure all attaching  
hardware is tightened securely - otherwise injury or damage may result.  
22NF batteries weigh 37 pounds each. GP24 batteries weigh 51 pounds each. Use  
proper lifting techniques (lift with your legs) to avoid injury.  
Use p/n M22NFSLDG batteries only. Failure to use the correct battery size and/or  
voltage may cause damage to your wheelchair and give you unsatisfactory  
performance.  
ALWAYS use a battery lifting strap when lifting a battery. It is the most convenient  
method and assures that the battery acid will not spill. It also helps to prolong the  
life of the battery.  
DO NOT tip the batteries. Keep the batteries in an upright position.  
NEVER allow any of your tools and/or battery cable(s) to contact BOTH battery  
post(s) at the same time. An electrical short may occur and serious personal injury  
or damage may occur.  
When tightening the clamps, always use a box wrench. Pliers will “round off” the  
nuts. NEVER wiggle the battery terminal(s)/post(s) when tightening. The battery  
may become damaged.  
The POSITIVE (+) RED battery cable MUST connect to the POSITIVE (+) battery  
terminal(s)/post(s), otherwise serious damage will occur to the electrical system.  
Install protective caps on POSITIVE (+) and NEGATIVE (-) battery terminals.  
DO NOT remove fuse or mounting hardware from POSITIVE (+) RED battery  
cable mounting screw.  
NOTE: If there is battery acid in the bottom of the battery tray or on the sides of the battery(ies),  
apply baking soda to these areas to neutralize the battery acid. Before reinstalling the existing or  
new battery(ies), clean the baking soda from the battery tray or battery(ies) being sure to avoid  
contact with skin and eyes. Determine source of contamination. Never install/reinstall a battery  
with a cracked or otherwise damaged case.

Screen  
Battery Gage  
Display  
segments will progressively disappear a  
bar at a time until no segments appear  
between E and F. At this level the user  
should charge the batteries as soon as  
possible.  
Charging Batteries  
WARNING  
NEVER attempt to recharge the batteries by attaching cables directly to the  
battery terminals or clamps. ALWAYS use the recharging plug located on the back  
of the joystick.  
DO NOT attempt to recharge the batteries and operate the power wheelchair at  
the same time.  
During use and charging, unsealed batteries will vent hydrogen gas which is  
explosive in the right concentration with air.  
CAUTION  
ALWAYS charge new batteries before initial use or battery life will be reduced.  
NOTE: For this procedure, refer to FIGURE 10.6 on page 72.  
NOTE: New batteries MUST be fully charged prior to initial use of the wheelchair.  
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 a long period of time.

SECTION 10—ELEVATE BATTERIES  
The range per battery charge using recommended batteries should be approximately 5 to  
9 hours of typical operation. Extensive use on inclines may substantially reduce per  
charge mileage.  
Description and Use of Battery Chargers  
The charger automatically reduces the charge from an initially high rate to a zero reading  
at a fully charged condition. If left unattended, the charger should automatically shut-off  
when full charge is obtained.  
There are some basic concepts which will help you understand this automatic process.  
They are:  
The amount of electrical current drawn within a given time to charge a battery is called  
the “charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate  
is high, as 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 GREEN light will stay illuminated  
for a longer period of time followed by a shorter off time.  
WARNING  
NEVER leave the charger unattended when the breaker has tripped. A fault condi-  
tion exists. Unplug and discontinue using immediately. Contact an Invacare dealer.  
NOTE: Ifperformingthechargingprocedures independently, READ andCAREFULLYfollowthe  
individual instructions for each charger (supplied or purchased).  
NOTE: If charging instructions are not supplied, consult a qualified service technician for proper  
procedures.

1. Attach the battery charger connector to the charger port on the joystick.  
2. Plug the chargers AC power cord, or extension, into the grounded 120 VAC wall  
outlet.  
3. Wait until charging is complete.  
NOTE: Allow eight hours for normal charging. Larger batteries (greater than 55 ampere-hours) or  
severely discharged batteries may require up to sixteen hours to be properly charged and equalized.  
NOTE: It is advantageous to recharge frequently rather than only when necessary. In fact, a  
battery’s life is extended if the charge level is maintained well above a low condition.  
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 Invacare dealer for service.
