Electromagnetic interference (EMI) from radio wave sources
It is very important that you read this information regarding the possible effects of electromagnetic interference on your Everest & Jennings® Everest with Captain Seat power wheelchair.
Powered wheelchairs may be susceptible to electromagnetic interference (EMI), which is interfering
electromagnetic (EM) energy emitted from sources such as radio stations, TV stations, amateur radio
(HAM) transmitters, two-way radios, and cellular telephones. 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 has an immunity level of 20 V/m.
Be aware that using different components, adding accessories, or modifying the powered wheelchair may
change the immunity level.
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 that follow, your risk to EMI exposure 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 talkies”, 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 telephones, laptop computers, AM/FM radios,
TV sets, CD players, and cassette players, and small appliances, such as electric shavers and hair
dryers, so far as we know, are not likely to cause EMI problems with 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 that follow are recommended to prevent possible interference with the control system of
the powered wheelchair.
Everest with Captain Seat Owner's Manual
GF0600050RevE06, August 2006
EMI Warnings
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM)
transmitters, two-way radios, and cellular telephones can affect powered wheelchairs. Following the
warnings listed below should reduce the chance of unintended brake release or powered wheelchair
movement which could result in serious injury.
WARNING: Do not operate hand-held transceivers (transmitters-receivers), such as citizens band (CB) radios, or turn on personal communication devices, such as
cellular telephones, while the powered wheelchair is turned on.
WARNING: Be aware of nearby transmitters, such as radio or TV stations, and try to
avoid coming close to them.
WARNING: If unintended movement or brake release occurs, turn the powered wheelchair off as soon as it is safe.
WARNING: 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).
WARNING: Report all incidence of unintended movement or brake release to GrahamField Health Products, 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 powered wheelchair model has an immunity level of 20 V/m.
Be aware that using different components, adding accessories, or modifying the powered wheelchair may
change the immunity level.

III Handling tips
The Everest & Jennings® Everest with Captain Seat has been designed and engineered to perform as a stable and well balanced unit when used as intended, but it is possible to tip the Everest with Captain Seat
over if used improperly. We urge you to learn the characteristics of your wheelchair. It is most important
to learn safe methods to perform the daily activities basic to your lifestyle. Consult healthcare professionals for assistance in developing the skills and proper techniques to perform all activities safely.
Balance
Proper balance is the key to maintaining the stability of your wheelchair. Reaching, bending, and transferring to or from a wheelchair will change the weight distribution and center of gravity of you and your
wheelchair. When performing such activities, do so as instructed in the following paragraphs to avoid
tipping the wheelchair.
Transfer activities
WARNING: Always ensure that wheelchair is on a stable, level surface, engage the
drive engagement levers, and turn wheelchair power off before transfer.
WARNING: Do not step on the footplates during transfer; this could cause the wheelchair to tip. Fold the footplates up during transfer. There is a critical moment when there is little or no seat platform beneath you. Take every precaution to reduce this unsupported distance before you attempt transfer.
Transferring to or from a wheelchair is a very difficult maneuver. Exercise extreme care when transferring
without the aid of either an attendant or a patient lift. Consult healthcare professionals for assistance in
developing your individual technique. Make sure that the wheelchair is stabilized, and will not move or
slide during the transfer. Take extra precaution to prevent tipping. Use good body mechanics to prevent
personal injury.
Reaching / bending
Although it is not recommended, you may find it occasionally necessary to lean or reach from your
wheelchair. Consult with healthcare professionals for assistance in developing your personal safe reaching
or moving techniques suited to your ability and restrictions.
Forward or sideward
WARNING: Do not attempt to reach objects if you are required to move forward in the
seat. Do not attempt to retrieve objects from the floor if you must reach
down between your knees. Do not shift your weight in the direction that you
are reaching and/or bending; this could cause the wheelchair to tip.
1. Maneuver the wheelchair as close as possible to the object you wish to reach.
2. Reach only as far as your arm will extend without changing your sitting position. If in doubt, reposition the wheelchair or ask for assistance.
Everest with Captain Seat Owner's Manual
GF0600050RevE06, August 2006
Backward
1. Maneuver the wheelchair as close as possible to the object; the casters will limit how close you can
get.
2. Reach only as far as your arm will extend without changing your sitting position. If in doubt, reposition the wheelchair or ask for assistance.
Ramps and Inclines
WARNING: During descent, ensure that the lowest point on the footplates clears the
ground safely.
WARNING: Do not attempt any incline or decline of more than 6 degrees (10% grade, or
one foot of rise or fall per ten feet of ramp length).
WARNING: Avoid changing direction while descending a ramp or incline, as this could
cause instability.
Most people are capable of negotiating short inclines without assistance, depending upon upper body
strength, endurance, and the degree of incline. Know your own capabilities and limitations in terms of
strength and endurance before attempting to negotiate an incline or decline. Practice with an attendant
or healthcare professional first before attempting any inclines, declines curbs or ramps. Always inspect
the ramp for hazards such as holes, slippery or uneven surfaces, etc. before starting up or down. If you
can not see the entire ramp, ask someone to inspect it for you.
Ascent
Lean the upper part of your body slightly forward as you ascend the incline. If it becomes necessary to
stop on the incline, avoid any abrupt or sudden forward movement as you resume climbing, this could
cause tipping.
Descent
Always face forward when going down, but do not lean forward; this could cause tipping. Lean slightly
backward to increase stability.
It is critical to keep the wheelchair under control at all times. Descent should be made slowly and steadily, allowing the wheelchair's control system to maintain a safe speed. Upon stopping, electromechanical
park brakes will engage to prevent the wheelchair from rolling.
Curbs and steps
Curbs, steps and stairways are dangerous obstacles that confront the wheelchair user. When you encounter curbs, find a way around, or use the ramps now available in most locations. If you encounter steps
and there is no ramp available, avoid the steps by utilizing the disabled designated elevators now required
in most locations.
WARNING: Never attempt to negotiate steps, stairs or escalators in your Everest with
Captain Seat.

VII Batteries
Batteries are of critical importance, require attention and maintenance, and will require periodic replacement. As batteries age, their ability to hold a charge decreases. Old batteries discharge much more
quickly than new batteries under the same driving conditions. This results in a decrease in the distance
the wheelchair can travel before batteries need to be charged. This decrease is often misinterpreted as a
problem with the wheelchair system, when in fact the batteries have simply reached the end of their useful lives and should be replaced. Properly maintained batteries can be expected to last approximately 9 to
18 months. The purpose of proper maintenance is to extend that life as much as possible, and to minimize the incidence of unsatisfactory wheelchair performance.
The Everest with Captain Seat uses two 12 volt deep cycle batteries, group size U1 or 22. For best performance, batteries with the highest possible amp-hour rating should be used.
s
Caution: Only deep cycle, sealed case construction batteries should be used in this device.
WARNING: Batteries contain sulfuric acid, which can burn eyes, skin, clothes, etc. Use
caution! Always wear safety glasses when working with batteries. If contact
occurs, flush immediately with water and get medical attention.
Guidelines to extending battery life
• Give the batteries a full charge before using them for the first time.
• Limit use of new batteries for the first ten charge/discharge cycles—avoid deeply discharging the batteries. New batteries are not capable of their rated output until they have been discharged a number
of times.
• Recharge batteries after every discharge. Discharging batteries deeply before recharging them will
shorten battery life. Do not leave partially discharged batteries idle for several days; charge them as
soon as possible after discharging.
• Charge batteries fully each time before using. Allow the charger to finish its charge cycle once
started. This will help prevent deeply discharging the batteries. Unlike some rechargeable batteries,
the batteries used on wheelchairs do not exhibit a significant “memory effect”—they will recharge to
their full capacity, even if only partially discharged before each charge.
• If you must store your wheelchair for a long period of time, charge the batteries weekly.
• Perform regular maintenance on the batteries. See maintenance schedule in Section VIII,
MAINTENANCE, for recommended regularity.

release the joystick—you must be able to hear the park brakes operate within a few seconds. Repeat the
test three times, pushing the joystick in reverse, left and right, respectively. If there is a problem, do not
operate the wheelchair. Contact your dealer.
Repairs of the electromechanical park brakes, which keep your Everest with Captain Seat from rolling
when stopped, should only be performed by an Graham-Field Health Products dealer.
Check anti-tippers
Check the anti-tippers at least once a week. Ensure that all parts of the anti-tippers are securely fastened.
Clean frame
Needed: soft cloth, mild soap and water solution
Wipe off base and seat frame frequently, at least once a week, using a soft cloth. Dry the wheelchair immediately if exposed to moisture. Clean frame every three months with a mild soap and water solution.
The frame does not need to be waxed. Do not use solvents, abrasive waxes, caustic chemicals or spray
silicone. Never use abrasive cleansers; they could scratch the finish. Never use steam or high pressure
cleaners.
Check & clean upholstery
Needed: soft cloth, mild soap and water solution
Check back and seat upholstery material at least once a month. Inspect for rips, tears and worn spots.
Clean back and seat upholstery material at least once a month with a soft cloth and a mild soap and
water solution.
Check arms

Ensure that all attaching hardware is present and tight.
Check footrests
Check footrests at least once a month. Inspect the mounting hardware to confirm secure fasteners.
Check for cracks, burrs or sharp edges. Ensure that the footplate extension knobs are secure and footplates will not accidentally slip.
36
GF0600050RevE06, August 2006
Everest with Captain Seat Owner's Manual
Check caster forks
Check the caster stems/forks for proper rotation at least every three months. The caster fork must swivel
freely to facilitate steering and handling. Adjusting the stem nut varies the amount of force required
to turn the caster. If the nut is too loose, the caster will flutter or shimmy; if the nut is too tight, the
wheelchair will be difficult to steer. If the caster requires adjustment, or the caster stem bearing requires
replacement, visit a qualified Graham-Field Health Products dealer. Ensure that stems are firmly attached
to forks, and that forks and stems are not bent. Evaluate all threads, locking nuts and bearings.
Clean Batteries
Perform this at least every three months. See Section VII, BATTERIES, REGULAR BATTERY MAINTENANCE, Clean batteries, for this procedure.
Clean battery terminals
Clean battery terminals at least every six months. See Section VII, BATTERIES, REGULAR BATTERY
MAINTENANCE, Clean battery terminals, for this procedure.
Inspect motor brushes
The motor brushes should be inspected for wear every six months and replaced as needed. This should be
performed by a Graham-Field Health Products dealer.
s
Caution: Badly worn brushes can result in damage to the motors or controller.
s
Caution: After replacing the brushes, run the wheelchair gently for the first few miles to allow
the brushes to seat properly.
Check bearings
The Everest with Captain Seat has bearings only in the caster wheels, not in the drive wheels. Always
be alert for unusual noises in the bearings or excessive caster wobble. These signs indicate that the bearings are becoming worn and may require replacement. The caster bearings should be inspected every six
months and replaced as needed. This should be performed by a Graham-Field Health Products dealer.

adjustments have been altered. If you are unsure of the solution or unable to diagnose the problem, do
not hesitate to ask your Graham-Field Health Products dealer for assistance. Most power drive problems
are battery related. As batteries age, their ability to hold a charge decreases. Older batteries discharge
much more quickly than new batteries under the same driving conditions. This results in a decrease in
the distance the wheelchair can travel before batteries need to be charged. This decrease is often misinterpreted as a problem with the wheelchair system, when in fact the batteries have simply reached the end
of their useful lives and should be replaced. Sometimes expensive components are unnecessarily replaced
when the batteries are the real problem. If an electrical problem exists, check the following:
Batteries
Make sure the batteries are fully charged. Test battery state-of-charge as described in Section VII, BATTERIES, REGULAR BATTERY MAINTENANCE. Keep the posts and terminals clean and tight.
Circuit Breaker
Your Everest with Captain Seat is equipped with a circuit breaker to protect the electrical circuits from
overload. It is located in the base end cover (front of wheelchair for rear wheel drive; back of wheelchair
for front wheel drive). In the event of an overload, the circuit breaker button will pop out. To reset the
circuit breaker, push the button in.
Note: If you experience a problem with your wheelchair and are unable to service it yourself, contact
the dealer from whom you purchased the wheelchair. If the dealer is unable to help you, contact
Graham-Field Health Products Customer Service Department .
Note: Use only Everest & Jennings® replacement parts. An Everest with Captain Seat parts catalog is
available through Graham-Field Health Products dealers (and on the internet, at www.grahamfield.com), to assist in the ordering of parts.
s
Caution:: A complete inspection of your wheelchair, including maintenance, servicing and safety
checks, should be handled by a qualified Graham-Field Health Products dealer at least once a year.
WARNING: Unauthorized modification or the use of non-Everest & Jennings® replacement parts could change the structure of the wheelchair, void the warranty,
and create a hazardous condition, which could result in serious personal
injury..
