INTRODUCTION
1. Safety
Please read and follow all instructions in this owner’s manual before
attempting to operate your power chair for the first time. If there is anything in
this manual you do not understand, or if you require additional assistance for
setup, contact your Magic Mobility Dealer before operating the Recreational
Vehicle. There are certain situations, including some medical conditions,
where the power chair user will need to practice operating the power chair in
the presence of a trained attendant. A trained attendant can be defined as a
family member or care professional specially trained in assisting a power chair
user in various daily living activities. The contents of this manual are based on
the expectation that a qualified healthcare professional has properly fitted the
power chair to the user and the prescribing healthcare professional has trained
the user in the operation of the Recreational Vehicle, the dangers that can be
encountered and assured themselves that the user is capable of this. Using
your Observer Mobility product safely also depends upon your own good
judgment and/or common sense, as well as that of your provider, caregiver,
and/or health professional. Observer Mobility is not responsible for injuries
and/or damage resulting from any person’s failure to follow the warnings,
cautions and instructions in this owner’s manual.
2. Transfers
It is recommended that you have a trained attendant present while you learn to
transfer yourself. To reduce the chance of injury, we recommend:
· Be sure the power is turned off (See section 6.5.4)
· Be sure the Power chair is not in freewheel mode (See section 5.3)
· Ensure armrests and footrests are swung away or removed
· Position yourself as far back as possible in the power chair seat to prevent the power
chair from tipping forward.
3. Motor Vehicle Transport
Recreational Vehicle positioning belts were not designed with the intent of providing
proper restraint during motor vehicle transportation. The Department of
Transportation has not approved any tie-down systems with specific Recreational
Vehicles for transportation of a user while in a Recreational Vehicle, in a moving
vehicle of any type.

www.discovermymobility.com
- 2 -
It is Observer Mobility’s position that Recreational Vehicle users are not transported
in vehicles of any kind while in Recreational Vehicles.
4. Weight Limitations
Your power chair is rated for a maximum weight capacity of 400 lbs (see table). Do
not carry passengers or heavy weights on any part of the Recreational Vehicle.
5. Stairs and Escalators
6. Transportation Products
If it is necessary to use a transportation product such as a hoist or lift,
Observer Mobility recommends that the manufacturer’s instructions and
specifications are closely reviewed before using that product.
7. Public Streets and Roadways

8. Stationary Obstacles: (Steps, Curbs, Etc.)
Proceed with extreme caution when driving near raised surfaces, unprotected
ledges, and/or drop-offs (curbs, porches, stairs, escalators, lifts etc). Always
approach an obstacle so both front wheels touch that obstacle together. Never
attempt to climb a curb or obstacle at an angle.
9. Climbing or Descending an Incline
When climbing an incline, try to keep your power chair moving; however do not use
excessive speed. If you must stop, start up again slowly and then accelerate cautiously.
If at anytime you feel uncomfortable, reduce your acceleration rate. When driving
down an incline, set your power chair to the slowest speed setting and drive in the
forward direction only. If your power chair starts to move down the incline faster than
you anticipated or desired, allow it to come to a complete stop by releasing the
joystick. Once the chair has stopped push the joystick forward slightly to ensure a
safely controlled descent. The following advice is recommended for your safety:
* Do not drive at an angle up or down the face of the incline. Drive your power chair
straight up or down the incline. This greatly reduces the possibility of tipping the
chair over. · Avoid potentially hazardous inclines e.g. areas covered with snow, ice,
mud, cut grass, or wet leaves.
* Avoid sudden stops and starts
* When on any sort of an incline or decline, never place the power chair in freewheel
mode while seated on it or standing next to it.
* Never attempt to travel backwards down an incline.
10. Maximum Recommended Incline
Most public access ramps have a maximum gradient 1 in 14 (AS1428.1). Therefore,
Observer Mobility recommends that the maximum slope of an incline you attempt to

www.discovermymobility.com
- 4 -
safely ascend or descend on your power chair does not exceed a 1 in 14 gradient.
11. Removable Parts
12. Cornering Information
Excessively high cornering speeds can create the possibility of tipping. If you feel that
you may tip over in a corner, immediately reduce your speed and steering angle (i.e.
lessen the sharpness of the turn) The following advice is recommended for your
safety:
* Reduce cornering speed
* Reduce steering angle
* Beware of uneven, rough and slippery terrain
* Avoid turning on inclined surfaces
* Be aware of changing surfaces - such as passing from a paved area to a gravel area
at high speed while turning.
* Avoid abrupt directional changes.
13. Electromagnetic Fields (more information is on page 10)
Your power chair’s performance may be influenced by electromagnetic fields caused

by mobile telephones or other radiating devices, such as hand-held radios, radio and
television stations, wireless computer links, microwave sources, and pagers. Your
power chair may also be a source of electromagnetic and radio frequency interference.
Be aware that your power chair may affect the performance of alarm systems and
other radiating devices.
14. Positioning Belts
Do not sit on your power chair while it is in a moving vehicle refer to section 3.2 Motor
Vehicle Transport. It is the obligation of the purchasers, therapists and other healthcare
professionals to determine if a positioning belt is required to ensure the safe operation of
this equipment by the user.

26. Electromagnetic Interference (EMI) From Radio Wave
Sources.
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS
INFORMATION REGARDING THE POSSIBLE EFFECTS OF
ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED
RECREATIONAL VEHICLE
Powered Recreational Vehicles 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 powered Recreational Vehicle to release its
brakes, move by itself, or move in unintended directions. It can also
permanently damage the powered Recreational Vehicle’s control system. The
intensity of the interfering EM energy can be measured in volts per meter
(V/m). Each powered Recreational Vehicle 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
Recreational Vehicle model as shipped, with no further modification, has an
immunity level of 3 V/m.
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 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 (transmitters-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. **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

www.discovermymobility.com
- 12 -
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, 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 to your powered Recreational Vehicle.
Powered Recreational Vehicle Electromaqnetic 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 Recreational
Vehicle's control system while using these devices. This can affect powered
Recreational Vehicle movement and braking. Therefore, the warnings listed
below are recommended to prevent possible interference with the control
system of the powered Recreational Vehicle.
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 Recreational Vehicles and motorized scooters.
Following the warnings listed below should reduce the chance of unintended
brake release or powered Recreational Vehicle movement which could result
in serious injury.
1) Do not operate hand-held transceivers (transmitters-receivers), such as
citizens band (CB) radios, or turn ON personal communication devices, such
as cellular phones, while the powered Recreational Vehicle is turned ON;
2) Be aware of nearby transmitters, such as radio or TV stations, and try to
avoid coming close to them;

www.discovermymobility.com
- 13 -
3) If unintended movement or brake release occurs, turn the powered
Recreational Vehicle OFF as soon as it is safe;
4) Be aware that adding accessories or components, or modifying the powered
Recreational Vehicle, may make it more susceptible to EMI (Note: There is no
easy way to evaluate their effect on the overall immunity of the powered
Recreational Vehicle)
5) Report all incidents of unintended movement or brake release to the
powered Recreational Vehicle 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 EM1 (as of May 1994) (the higher the level, the greater the protection);
2) This product has an immunity level of 3 V/m.

PG CONTROLLER OPERATION
The joystick controls may be customized and may be one of a number of
different models depending upon users requirements. This manual contains
information on the standard joystick control.
27. Joystick power
If the power Recreational Vehicle begins to move in an unexpected manner,
immediately release the joystick and turn the Recreational Vehicle off. Unless
the joystick is damaged, this should stop your power chair.
If the joystick is not in the neutral (centre) position when you turn on the power,
you may cause a fault in the system. Releasing the joystick and turning the
power off and on again will reset the system.
WARNING ! In case of unexpected movement turn off the power and
gradienter switch.
28. Rain and Water
The joystick hand control unit IS NOT WATERPROOF. The joystick module is
splash proof but may be permanently damaged if water transgresses the
rubber seals (this damage is not covered under warranty).
We recommend carrying a plastic bag large enough to cover the joystick
module and the user’s hand, in case of rain.
