Unscrew the knurled knob from the seat holder tube and remove the seat. Insert the seat into the holding tube
and screw in the knurled knob to secure the seat in position.
Unscrew the adjustment handle on the front tiller and adjust the tiller to suit the user. Retighten the adjustment
handle to secure.

ELECTROMAGNETIC INTERFERENCE
Powered wheelchairs / scooters 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 telephones.
The interference from radio sources can cause the powered wheelchair / scooter to release its brakes, move by
itself or move in unintended directions. It can also permanently damage the main control system system. The
intensity of the interfering EM energy can be measured in volts per metre (V/m). Each powered wheelchair /
scooter can resist EMI up to a certain intensity. This is known as the units ‘immunity level’. The higher the
immunity level, the greater the protection. At this current time, current technology is capable of achieving at
least a 20 V/m immunity level, which would provide useful propection from the common sources of radiated
EMI.
Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source),
the EM fields from hand-held radio soucres (transceivers) are of special concern.
It is possible to
unintentionally bring high levels of EM energy very close to the powered wheelchair’s of scooter’s control
system whilst using these devices.
The sources of radiated EMI can be broadly classified in to three types:
1.
Hand-held portable transceivers (transmitters-receivers) with antenna mounted directly on the
transmitting unit. Examples include citizens’band (CB) radio, ‘walkie talkies’ security, fire and
police transceivers, cellular (mobile) telephones and other personal communication devices.
NOTE: Some cellular telephones and similar devices transit signals while they are ON, even
when not being used.
2.
Medium-range mobile transceivers, such as those used in police cars, fire engines,
ambulances and taxis. These usually have the antenna mounted on the outside of the
vehicle.
3.
Long-range transmitters and tranceivers, such as cordless phones, laptop computers, AM/FM
radios, TV sets, CD players and cassette players, and small appliances such as eletric
shavers and hairdryers, so far we know, are not likely to cause EMI problems to your
powered wheelchair / scooter.
Following guidelines set out below should reduce the chances of unintended brake release or powered
wheelchair . Scooter movement, which could result in serious harm or injury.
1.
Do not operate hend-held tranceivers, such as citizens’ band (CB) radios, or turn ON
personal communication devices such as cellular telephones, while the powered wheelchair /
scooter is turned ON.
2.
Be aware of nearby transmitters, such as radio or TV stations, and try to aviod coming close
to them.
3.
If unintended movement or brake release occurs, turn the powered wheelchair / scooter OFF
as soon as it is safe to do so.
4.
Be aware that adding accessories or components, or modifying the powered wheelchair /
scooter, may make it more susceptible to EMI.
5.
Report all inceidents of unintended movement or brake release to the powered wheelchair /
scooter manufacturer, and note whether there is a source of EMI nearby.
