WARNING –Do not travel up an incline with the seat completely reclined
without an attendant. Inclines vary, and doing so may decrease stability.
WARNING –Do not, under any circumstances, travel on a slope greater
than the maximum climbing angle for this power wheelchair. Please refer
to Section XII SPECIFICATIONS for this information. Exceeding the climbing
angle may cause unstable conditions.
FREEWHEEL GUIDELINES
Your power wheelchair is equipped with manual freewheel levers to maneuver the
unit without power. The manual freewheel levers can be engaged or disengaged.
Disengaged, or “freewheel” mode, releases the locking mechanism on the gearbox
allowing the power wheelchair to roll freely with or without power.
Engaged, or “drive” mode, secures the locking mechanism on the gearbox preventing
the power wheelchair from rolling freely.
WARNING –Never attempt to personally put your power wheelchair in
freewheel mode while seated in the unit.
WARNING –Never put the power wheelchair in freewheel mode while on
an incline. This may cause uncontrollable movements.
ATTENTION –When your power wheelchair is in freewheel mode you may
feel resistance when maneuvering; this is normal, and prevents damage
to the gearbox.
ATTENTION –Please refer to Section V PARTS to locate the freewheel
levers on your power wheelchair.
SUGGESTION –If you hear a “clicking” noise when moving the joystick,
but the power wheelchair will not move –turn off the power, engage the
freewheel levers, and power back on to continue.

BRAKES & STOPPING
Coming to a stop in your power wheelchair can simply be done by releasing the
joystick. The joystick will automatically return to the center position, and the power
wheelchair will come to a stop.
ATTENTION –Quickly moving the joystick in the opposite direction of
travel will cause the power wheelchair to come to an abrupt stop, and if
held continuously in the opposite direction may cause erratic movements
if you are unfamiliar with the controls.
Your power wheelchair is equipped with two types of brake systems:
Regenerative brakes –when the joystick is returned to the center position, or
stop neutral position, regenerative brakes use electricity to quickly decelerate
the vehicle.
Park brakes –once the power wheelchair comes to a complete stop the park
brake activates automatically locking the drive wheels.
OUTDOOR OPERATION & INCLEMENT WEATHER PRECAUTIONS
While your power wheelchair is purposed for in-home use to assist you in daily living
activities; Drive Medical understands there are times you need to operate the power
wheelchair outdoors, and has designed it to perform superbly on level outdoor
surfaces.
ATTENTION –When operating outdoors avoid uneven terrain, soft
surfaces, tall grass, loose gravel, loose sand, fresh water, salt water, edges
of streams, lakes or oceans. If you are unsure about a surface, avoid it.
Exposure to inclement weather should always be avoided. If you find yourself caught
in inclement weather while operating your power wheelchair, proceed to the closest
shelter immediately. Completely dry your power wheelchair before operating,
charging, or storing.

Electromagnetic interference (EMI) tests have shown to produce adverse effects on
the performance and control of electrically powered mobility devices.
EMI can be produced from different sources such as cellular phones, two-way radios,
radio stations, television stations, amateur radio transmitters (HAM), wireless
computer links, microwave signals, paging transmitters, and transceivers used by
emergency vehicles.
The EMI waves can cause unintentional movement of the power wheelchair, or
damage to the controller. Every electrical powered mobility device has a resistance to
EMI. The higher the resistance level the greater the protection. The intensity of the
interference can be measured in volts per meter, V/m.
At this time, current technology is capable of achieving an immunity level of 20 V/m,
which provides protection from more common sources of EMI. Your power
wheelchair, with no modifications, has an immunity level of 20 V/m.
EMI becomes more intense as you move closer to the source. The EMI produced from
hand-held radios are of special concern. It is possible to unintentionally bring high
levels of EMI very close to the power wheelchair’s control system, effecting your
movement and braking. The warnings listed below are recommended to prevent
possible interference with the control system of your power wheelchair.
WARNING –Do not operate hand-held transceivers such as CB (citizens
band) radios, or turn on personal communication devices, such as cellular
phones, while the power wheelchair is powered on.
WARNING –Be aware of nearby transmitters, such as radio or television
stations, and avoid close proximity.
WARNING –If you experience unintended movement or brake release
occurs, power off as soon as it is safe. Please report EMI incidents to Drive
Medical.
