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.

3/13/2008 5
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.

3/13/2008 6
Powered 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.

Driving Your Shoprider Powerchair
Ramps, Slopes and Cambers
The Shoprider Trooper 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 Trooper Powerchair
First Time Use
Prior to using your Trooper 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 life.
Tires
Since your tires are flat free tires, there is no need to ever worry
about tire air-pressure.
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 Trooper 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.
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
assy) and castor assemblies be checked and cleaned
occasionally for hair and debris build-up, which will hinder the
performance of the unit.
Check the batteries on a regular basis. For extended battery life
it is highly recommended that the batteries be fully charged
after each use and that the battery pack always be turned off
when not in 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.
Active users: Charge daily
Occasional users: Charge your battery before any outing and
always after active use.

Batteries & Battery Charging
Batteries
The Shoprider Trooper Powerchair is designed to operate on two 12
volt/36Ah sealed lead acid (AGM or gel-cell type) aka SLA
maintenance free batteries. For easy handling, the SLA batteries are
contained within a battery-pack. The life of the batteries may be
affected by temperature, terrain, weight of user, driving methods, and
care of batteries. The battery gauge (Refer to Figure 3) is a guide on
the remaining charge of the batteries.
The active user will need to charge the batteries after using
approximately 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 (Refer to Figure 10). For extended battery life,
it is highly recommended that these guidelines be followed. You
cannot over charge the batteries.
*Keeping the batteries charged extends the life of the batteries*
SLA batteries should be kept fully charged at all times. They must not
be left in a discharged state if the unit is not being used for some time
or the “charging space” within the batteries will be permanently lost
(memory loss). The SLA batteries should be checked once a month
and kept charged as needed. Typically SLA batteries have up to
about 400 charging cycles.
