Attention
When climbing an incline, do not zigzag or drive at an angle up the face of the of the
incline.
Always drive your power wheelchair straight up the incline. This greatly reduces the
possibility of a tip or a fall. Always exercise extreme caution when negotiating an
incline.
Never travel up or down an incline that is or covered by snow or ice.
■ Inclines and uneven terrain
When climbing an incline, try to keep your power wheelchair moving. If you must stop, start up again
slowly and then accelerate cautiously. When driving down an incline, do so slowly and in the forward
direction only. If your power wheelchair starts to move faster than you anticipated or desired it would,
allow the wheelchair to come to a complete stop by releasing the joystick. Push the joystick slightly
forward and continue traveling slowly down the incline.
■ Maximum recommended incline
The Sunfire Plus EC Power Wheelchair has undergone extensive incline testing. Our results show that
the maximum incline your Sunfire Plus EC can safely climb is eight degrees at maximum weight

2 . S A F E T Y N O T I C E
This section provides the user with basic information that describes the problems with electromagnetic
interference (EMI), known sources of EMI, protective measure to either lessen the possibility or
exposure or to minimize the degree of exposure, and suggested action should unexpected or erratic
movement occur.
Attention
It is very important that you read this information regarding the possible effects of
electromagnetic interference on your Sunfire Plus EC power wheelchair.
■ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE SOURCES
Powered wheelchair’s 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 power 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 power 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 power wheelchair model has as shipped as with no further modification an immunity level
of 20 V/m without any accessories.
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 warning 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 ( transmitter-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.
Attention Some cellular telephones and similar transmit signal 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 power wheelchair.
3. Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio and
TV broadcast antenna towers) and amateur (HAM) radios.

8
3 . E M I
Attention Other types of hand-held devices, such as cordless phones, laptop computers,
AM/FM radios, TV sets, CD players, cassette and small appliances such as
electric shavers and hair dryers are not , likely to cause EMI problems to your
powered power wheelchair .
■POWERED POWER 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 closer to the powered s control
system of power wheelchair while using these devices. This can affect powered power wheelchair
movement and braking. Therefore, the warnings listed below are recommended to prevent possible
interference with the control system of the powered power wheelchair.
■WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio
(HAM) transmitters, two-way radios, and cellular phones can affect powered power wheelchair and
motorized power wheelchair. Following the warnings listed below should reduce the chance of
unintended brake release or powered power wheelchair movement which could result in serious
injury.
1. Do not operate hand-held transceivers-receivers, such as citizens band (CB) radios, or turn ON
personal communication devices such as cellular phones, while the powered power 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 power wheelchair OFF as
soon as it is safe;
4. Be aware that adding accessories or components, or modifying the powered power 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 power wheelchair).
5. Report all incidents of unintended movement or brake release to the powered power 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
(the higher the level, the greater the protection);
2. This product has an immunity level of 20 V/m without any accessories and connected to it.

■JOYSTICK DEPTH ADJUSTMENT
Your power wheelchair may be equipped with an adjustable joystick. This function enables you to
move the joystick from the armrest to the desired position.
Suggestion
1. You should recharge the batteries after each time the power wheelchair is used to ensure maximum
range. The batteries should be charged at least once a week, even if the power wheelchair is not used.
2. After charging or replacing a new battery, drive the power wheelchair for 2-3 minutes to make sure
the battery capacity is sufficient.
3. In cold weather, the battery may respond more slowly and the battery range may be reduced.
4. When driving on a gradient, the battery indicator light may move up and down. This is a normal
phenomenon and should not cause concern.
5. Even with proper care and use of the battery it is natural for the battery’s capacity to reduce with
time. Therefore, the battery’s range is about 50% of the range when the batteries were new, it is time
for it to be replaced. Please contact your dealer about replacement batteries. If an old battery is used,
it can lead to a rapid decline in performance.
6. The battery range will be reduced when driving frequently, on a slope or on rough terrain, as this
requires a greater consumption of power.
7. The batteries have a six-month warranty covering manufacturing defect. This warranty does not
cover faults due to incorrect battery recharging.
■BRAKING

BATTERIES
◆ The Sunfire Plus EC Power Wheelchair uses two long- lasting, 12 volt, deep-cycle batteries. These
batteries are sealed and maintenance free. Since they are sealed, there is no need to check the
electrolyte (fluid) level. Deep-cycle batteries are designed to handle a longer and deeper discharge.
Though they are similar in appearance to automotive batteries, they are not interchangeable.
Automotive batteries are not designed to handle a long, deep discharge and are unsafe for use in
powered power wheelchairs.
◆These batteries are maintenance free and there is no need to refill with water.
◆Do not expose the battery to temperatures below 10C or above 50C when charging or storing
the power wheelchair. Under the above temperature range can cause the battery either to freeze or
overheat, causing damage and shortening its life.
▇ Use proper batteries
◆ Your power wheelchair operates on two 12 volt batteries.
◆ They should be U1 size with minimum of 36ampere hour rating . Only deep cycle sealed case
construction batteries should be used in the power wheelchair.
◆ When you buy a replacement, insist on a deep cycle sealed case. Do not use any other type.
CHARGING THE BATTERIES
The battery charger is essential in providing long battery life. Located underneath the utility tray, it is
designed to optimize your Sunfire Plus EC performance by charging safely, quickly and easily. The
power wheelchair amp meter and charger plug are located on the utility tray for easy viewing. The
Amp meter indicates the rate of charge being administered to fully recharge the batteries. It is also a
good indication of whether or not the charger is working. The Amp meter and the charger are only
functional when the charger power cord is plugged into a wall outlet.
▇ To charge the batteries using the onboard charger
◆ Position the rear of Sunfire Plus EC close to a standard wall outlet.
◆ Be certain the controller power is turned off and the freewheel levers are in the engaged position.
◆ Slide the cover of charger plug.
◆ Extend the charger power cord and plug it into the wall outlet.
◆ The Amp meter indicates how much charge is needed to fully charge the batteries. Wait about a
minute for the charger to warm up. The Amp meter may move as high as 3 amps, then gradually
move back down to 0 amps as the batteries charge.
We recommended you charge the batteries for 8 to 14 hours. As the batteries charge, the Amp
meter needle slowly drops to zero. When the batteries are fully charged, the needle vibrates on or
near the zero mark on the Amp meter scale.
◆ When the batteries are fully charged, unplug the power cord from the wall outlet.
◆ Replace the cover of charger plug.
Warning!
Battery posts, terminals and related accessories contain lead and lead compounds.
