2 SAFETY
2.3
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).

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.

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.
Invacare® Formula™ CG Seating

Part No 1143155
2 SAFETY
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.

WARNING
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 Invacare may adversely affect the EMI immunity
levels.

A Note About Drive Lock-Out

WARNING
NEVER operate the wheelchair or elevate/lower the seat while 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 vertical, 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.
One of the following will occur when the drive lock-out feature has been activated:
•
CMPJ+ Joysticks Only -  TILT WARNING or  SPM Inhibited displays on the joystick or display unit.
•
SPJ+ Joysticks Only - Left to right chase alternating with a steady display.
Drive lock-out is a feature designed to prevent the wheelchair from being driven after the seating system has been tilted 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 user’s line of sight while driving. Make sure the wheelchair user can see properly to
ensure safe driving.

*20° back angle can be any combination of recline, tilt, back angle and/or surface angle.
Refer to Typical Product Parameters on page 11 for tilt and/or recline angle ranges.

Using the Joystick to Drive the Wheelchair

For this procedure, refer to FIGURE 5 on page 39.
The joystick is located on 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 wheelchair to move in that direction.
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 knob to the appropriate setting.
2.
Turn the power On. Refer to Turning the Power On/Off on page 37.

Joystick
The joystick has proportional drive control, meaning that the further the joystick is 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.
Information Gauge Display
The information gauge display is located on the front of the joystick housing and provides the following information to the user on the status of the
wheelchair:
1.
Power is On.
2.
True state-of-battery-charge, including notification of when the battery requires charging:
A. GREEN LEDs are lit, indicating well charged batteries.
B. AMBER LEDs are lit, indicating batteries are moderately charged. Recharge batteries before taking a long trip.
C. RED LEDs are lit, indicating batteries are running out of charge. Recharge batteries as soon as possible.
The Information Gauge display also serves as a system diagnostic device when a fault is detected by the control module. A specific number of flashes
of the LEDs indicate the type of fault detected. Refer to Information Gauge Display Diagnostics on page 116 for the diagnostic indications of the
wheelchair status.
Service Indicator
The AMBER service indicator
will light when an error or fault occurs. Refer to Service Indicator Light Diagnostics on page 117 for a listing of the

On/Off - 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.

WARNING
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. Use proper lifting techniques (lift with your legs) to avoid injury.
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.
Unless otherwise indicated, make sure power to the wheelchair is OFF before performing these procedures.
After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely otherwise injury or damage may occur.
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/
