EMI WARNING
Electromagnetic Interference (EMI) from Radio Wave Sources
Powered electric chairs may be susceptible to electromagnetic interference, which is a
kind of 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 chairs to
release its brakes, move by itself or move in unintended directions. It can also
permanently damage the powered chair’s control system.
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.
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 problems to your Powerchair.

5
Power Chair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense the closer one moves to the
transmitting antenna (source), the EM fields from hand-held radio sources (transceivers)
are of special concern. It is possible to unintentionally bring high levels of EM energy
very close to the Powerchair’s control system while using these devices. This can affect
the Powerchair’s movement and braking. Therefore, the warnings listed below are
recommended to prevent possible interference with the control system of the
Powerchair.
WARNINGS
The following warnings listed below should reduce the chance of unintended brake
release or Powerchair movement, which could result in serious injury.
1. Do not operate hand-held transceivers (transmitter-receivers), such as citizens
band (CB) radios, or turn ON personal communication devices, such as cellular
phones, while the Powerchair 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 Powerchair OFF as
soon as it is safe.
4. Be aware that adding accessories or components, or modifying the Powerchair
may make it more susceptible to EMI.
NOTE: There is no easy way to evaluate the overall immunity of the powered
chair.
Report all incidents of unintended movement or brake to your Powerchair provider, and
note whether there are sources of EMI nearby.
NOTE: The Shark controller EMI rating is FDA Regulated and conforms to federal
regulations.

Driving Your Shoprider Powerchair
Ramps, Slopes and Cambers
The indoor/outdoor Powerchair has the ability to negotiate ramps, slopes and cambers
of a low to medium gradient. It is of the utmost importance that the following points are
observed:
1. Never attempt to go up or down an incline which has a rough, wet or slippery
surface (loose gravel, tree roots, wet grass, polished floor, etc.)
2. Always approach an incline head on, not at an angle
3. Always travel at a speed that you are comfortable with and that you feel in
complete control
4. Avoid sudden or erratic action with the joystick
5. Always have the reclining seat in the most upright position when driving up an
incline
6. When riding along in a straight line you may experience “veering to one side”.
This is due to the natural camber in the construction of the pavement. To correct
this you simply have to steer slightly against it, as you continue to move forward

Caring for Your Shoprider 888WNLD Powerchair
First Time Use
Prior to using your Powerchair for the first time, you must charge the batteries fully (refer
to Battery Charging Procedures). Charging may take up to 12 hours. Charging the
batteries completely prior to first time use will benefit battery efficiency and battery life.
Tires
Since your tires are flat free tires, there is no need to ever worry about tire air-pressure.
When tread is worn, it is highly recommended to replace tires.
General Maintenance and Lubrication
Inspection for loose wheel bolts, seat and arm tightening bolts, castor nuts and
other nuts and bolts is recommended on a regular basis.
Most lubricated components on the Powerchair are designed to be maintenance
free and are sealed. Therefore, lubrication is not required for these components.
However, the driving wheel axles and seat post should always have a very light
coat of multi-purpose grease. **NOTE** Never put grease or oil in the breather
cap located on the top of each worm gear.
DO NOT USE TOO MUCH GREASE!
Drips may stain or damage carpets, furnishings, etc.
It is recommended that the driving axles (inside the drive wheel assembly) and
castor assemblies be checked and cleaned occasionally for hair and debris build-
up, which will hinder the performance of the unit.
Check the 888WNLD’s batteries on a regular basis. For extended battery life, it is
highly recommended that the batteries be fully charged after each use. If the
batteries are weak, severely discharged or old, a variety of problems may occur
with the unit including charging problems, reduced speed, loss of range, loss of
charge capacity and others. Please contact your provider for battery replacement
and proper disposal. Note: Charging your batteries daily will enhance the life of
your batteries. If the batteries are left unattended for extended periods of time, it
is recommended that they be left in a fully charged state. Leaving your batteries
in a discharged state, or not charging them regularly will diminish the life of your
batteries and cause irreversible damage to your batteries.

16
Batteries & Battery Charging
Batteries
The Powerchair is supplied with 4 x 35/36 Ah sealed lead acid, maintenance free
batteries. These are located under the seat in the center of the Powerchair. For easy
handling, Velcro or plastic carrying straps may be provided to assist in installation or
removal of the batteries. The duration of the batteries can be affected by temperature,
terrain and weight of the user. The Battery Gauge is a guide on the remaining charge in
the batteries.
The active user will need to charge the batteries after using approximately more than
30% of battery capacity. As an inactive user, only using from once a week to
every other day, the recharge point would be at 50% of discharge.
The Battery Gauge is used to indicate power on and
provides an estimate of the remaining battery
capacity.
Any green LEDs lit indicate well charged batteries.
If only amber and red LEDs are lit, the batteries are
moderately charged. Recharge before undertaking
a long trip.
If only red LEDs are lit, the batteries are running out
of charge. Recharge as soon as possible
