2. SAFETY NOTICE

9
This section provides the user with basic information that describes the problems with electromagnetic
interference (EMI), known sources of EMI, protective measure to either lessen the possibility or
exposure or to minimize the degree of exposure, and suggested action should unexpected or erratic
movement occur.
Attention: It is very important that you read this information regarding the possible effects o
f
electromagnetic interference on your Geo power chair.
■ ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE
SOURCES
Powered chairs 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 power chair to release its brakes, move by itself, or move in unintended directions. It can
also permanently damage the powered wheelchair’s control system. The intensity of the interfering EM
energy can be measured in volts per meter (V/m). Each power chair can resist EMI up to 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 power chair model has
as shipped as with no further modification an immunity level of 20 V/m without any accessories.
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 warning 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 ( transmitter-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.
Attention: Some cellular telephones and similar transmit signal 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.
3. Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio and TV
broadcast antenna towers) and amateur (HAM) radios.
3. EMI

0
Attention: Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM
radios, TV sets, CD players, cassette and small appliances such as electric shavers and hair dryers
are not , likely to cause EMI problems to your powered power chair .
■ POWERED POWER CHAIR ELECTROMAGNETIC 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 closer to the powered s control system
of power chair while using these devices. This can affect powered power chair movement and
braking. Therefore, the warnings listed below are recommended to prevent possible interference with
the control system of the powered power wheelchair.
■ 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 power chair and
motorized power chair. Following the warnings listed below should reduce the chance of unintended
brake release or powered power chair movement which could result in serious injury.
1. Do not operate hand-held transceivers-receivers, such as citizens band (CB) radios, or turn ON
personal communication devices such as cellular phones, while the powered 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 powered power chair OFF as soon as it is
safe;
4. Be aware that adding accessories or components, or modifying the powered power chair, may
make it more susceptible to EMI (Note: There is no easy way to evaluate their effect on the overall
immunity of the powered power chair).
5. Report all incidents of unintended movement or brake release to the powered power wheelchair
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 EMI ( the higher
the level, the greater the protection);
2. This product has an immunity level of 20 V/m without any accessories and connected to it.

Suggestion
1. You should recharge the batteries after each time the power chair is used to ensure maximum range.
The batteries should be charged at least once a week, even if the power chair is not used.
2. After charging or replacing a new battery, drive the power chair for 2-3 minutes to make sure the
battery capacity is sufficient.
3. In cold weather, the battery may respond more slowly and the battery range may be reduced.
4. When driving on a gradient, the battery indicator light may move up and down. This is a normal
phenomenon and should not cause concern.
5. Even with proper care and use of the battery it is natural for the battery’s capacity to reduce with time.
Therefore, the battery’s range is about 50% of the range when the batteries were new; it is time for it to
be replaced. Please contact your dealer about replacement batteries. If an old battery is used, it can lead
to a rapid decline in performance.
6. The battery range will be reduced when driving frequently, on a slope or on rough terrain, as this
requires a greater consumption of power.
7. The batteries have a six-month warranty covering manufacturing defect. This warranty does not cover
faults due to incorrect battery recharging.
