General Warnings Please take the time to carefully study all the following warnings. They are designed to help you avoid an accident which may lead to injury to you or to others.
Warning #1 - Electromagnetic interference !
What is electromagnetic interference (EMI) ? Electromagnetic interference is the interference that may occur as a result of electromagnetic energy emitted from radio wave sources. Such radio waves can adversely affect the operation of electronic devices, such as the controller on your wheelchair.
Sources of electromagnetic interference Sources that emit electromagnetic energy can be broadly classified into three groups: Hand held portable transceivers Medium range mobile transceivers
Long range transmitters and transceivers
eg mobile phones, CB radios. These devices have the antenna mounted on them. eg radios and other communications equipment on police, fire, ambulance and other emergency vehicles. The antenna is normally mounted on the outside of the vehicle. eg commercial radio and TV stations, HAM radios, microwave stations
Page 13 of 25
March 2012
AC Mobility User Manual for the Atigra Mid Wheel Drive electric wheelchair The closer the chair is to the source of the EMI, the greater the potential impact of the EMI on the operation of the chair.
The effect of electromagnetic interference on your wheelchair It is important that you are aware of the potential dangers that may arise from EMI with the operation of your chair. Such interference may appear as the unintended release of the electric brakes on the chair and possibly movement of the chair by itself or movement of the chair in unintended directions. EMI can also permanently damage the wheelchair control system. The interference can occur without warning. Any of these effects could result in severe injury to you or other people or cause other property damage! Please remain vigilant for the possible effects of EMI and take care in the operation of your chair.
Immunity to interference Wheelchairs differ in their ability to resist EMI. An immunity level of 20 volts per metre or more (a higher level is better) is desired for reasonable protection against the common sources of EMI.
How to avoid EMI Sources of intense electromagnetic fields as listed above may be encountered when driving your chair. Some of these sources will be obvious and can be easily avoided. Some sources however will not be obvious and exposure to the electromagnetic fields will be unavoidable. You can help to avoid possible problems by : being aware of sources of electromagnetic interference and their location, such as radio or TV stations, and avoiding coming close to them being aware of hand held devices that may be brought close to the chair. You should switch off the power to the chair should you be aware that any source of possible electromagnetic interference has been brought close to the chair being aware that adding accessories or components, or modifying the wheelchair or its controller system, may make the wheelchair more susceptible to EMI
!
If the chair shows any signs of electromagnetic interference, you should switch off your chair immediately. Do not attempt to turn the power on and drive the chair until you are satisfied that the source of electromagnetic interference is no longer present and you are able to drive the chair safely.
Warning – use of devices that emit electromagnetic interference
!
Do not attempt to turn on or use a hand held transceiver or other hand held communication device eg CB radio, mobile/cellular phone while your wheelchair is switched on.
Advising your dealer You should contact your dealer immediately and report any unintended electric brake release or movement of the chair. Please advise your dealer if there was a source of electromagnetic interference nearby.

To slow down and stop, allow the joystick to return to the centre position. The chair will slow down and stop. When stopped, the electromagnetic park brakes on each motor will engage and prevent the chair from moving.
Do not use ON/OFF button to stop the chair except in an emergency. The wheelchair may stop suddenly, causing you to fall from the chair. This may cause personal injury.

Batteries Warnings
Batteries contain sulphuric acid which can burn your skin, eyes or clothing. Do not allow battery acid to get on your chair or surrounding areas as damage may result. Always keep batteries upright. Always wear protective clothing and gloves when checking or changing batteries in your chair. When changing batteries, seek help from your dealer or other qualified service personnel. Batteries are heavy and must be handled carefully to avoid personal injury. Batteries must be installed correctly, ensuring that the cables are connected to the correct battery terminals. Batteries store energy – be careful that metal objects (including jewellery that you may be wearing) are not allowed to touch the battery terminals, causing them to short circuit. This could cause burns or a fire!
Battery type Your Atigra Mid Wheel Drive uses two 12 volt deep cycle batteries to drive the wheelchair. Use only gel or sealed case, low maintenance type, batteries with a minimum rating of 28 ampere hour. Batteries of 38 amp hour or greater are preferred.
