ELECTROMAGNETIC INTERFERENCE AND WARNINGS
CAUTION: It is very important that you read this information regarding the possible effects of Electromagnetic Interference on your power chair.
Powered wheelchairs and motorized power chair may be susceptible to electromagnetic interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources such a radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios, and cellular phones. The interference (from radio wave sources) can cause the motorized power chair to release its brakes, move by itself, or move in unintended directions. It can also permanently damage the motorized power chair control system. The intensity of the interfering EM energy can be measured in volts per meter (V/m). Each motorized power chair can resist EMI up to a certain intensity. This is called its "immunity level." The higher the immunity level, the greater the protection will be. 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. The immunity level of this motorized power chair model is 20 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 typesj
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.
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.
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 motorized power chair.
Power Chair Electromagnetic Interferencej
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 power chair control system while using these devices. This can affect power chair movement and braking. Therefore, the warnings listed below are recommended to prevent possible interference with the control system of the power chair.
Warningsj
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM) transmitters, two-way radios, and cellular phones can affect the power chair. Following the warnings listed below should reduce the chance of unintended brake release or power chair movement, which could result in serious injury.

SEREN

Instruction Booklet

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 power chair 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 power chair OFF as soon as it is safe;
4. Be aware that adding accessories or components, or modifying the power chair, may make it more susceptible to EMI; and
5. Report all incidents of unintended movement or brake release to the distributor on the back cover of this manual. 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 EMI
(as of May 1994). The higher the level, the greater the protection.
2.The immunity level of this product is 20 V/m.

2.2 Battery charging
Plug the battery charger into the Remote's XLR socket.

The Battery Gauge will indicate the system is being charged by cycling between a left-to-right chase sequence, and then displaying the approximate battery charge state at the end of the chase sequence.

Driving is prevented (inhibited) while the system is being charged.

The LE system does not have to be powered up when charging the battery, however, if it is not powered up, then the battery gauge will not display the charging state/ chase sequence.

Figure 35 Battery charging chase sequence

Warning:
The maximum charging current for the LiNX LE System is 6A. The wheelchair manufacturer must specify an appropriate battery charger for the batteries used in the wheelchair. The wheelchair manufacturer must also specify the maximum current of any battery chargers to be used with the controller and warn against using battery chargers of higher current ratings. The battery charger must have over-current protection in the form of a non-resettable fuse. It is the responsibility of the wheelchair manufacturer to manage the risks of battery over-charging and any related gas emissions. To protect the wheelchair wiring from over currents while charging the batteries, chargers must have the ability to reduce their current output when electrically shorted.
