SAFETY INSTRUCTIONS
The following guidelines are intended to assist you in the safe operation of your
TG400R scooter. If you have any questions about the correct operation of your
scooter, please contact your authorized dealer. Consult your physician if in doubt
of your ability to operate the scooter.
Your scooter can negotiate grass, gravel, dirt, and sand surfaces, as well as hard
paved or carpeted surfaces. However, extra caution should be taken when
operating your unit on uneven surfaces.
There are some concerns about electromagnetic interference to powered
wheelchairs and scooters. You need to know what EMI (Electromagnetic
Interference) is and how to prevent such incidents. The following paragraphs
suggested by the FDA are intended to provide you some important information
about this.
CAUTION:
IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION
REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC
INTERFERENCE ON YOUR POWERED SCOOTER.
Electromagnetic Interference (EMI) From Radio Wave Sources
Powered wheelchairs and motorized scooters (in this text, both will be referred to
as powered wheelchairs) 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 mobile phones. The interference (from radio wave sources) can
cause the powered wheelchair 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 powered wheelchair can resist EMI up
to a certain intensity. This is called its “immunity level.” The higher the immunity
level is, 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. The immunity level of this
powered scooter as shipped, with no further modification, is not known.
There are ample 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, mobile telephones,
and other personal communication devices. **Note: Some mobile telephones
and similar devices transmit signals while they are ON, even when not being
used.
