GENERAL WARNINGS (CONTINUED)
WEIGHT TRAINING
Invacare DOES NOT recommend the use of its wheelchairs as a weight training apparatus. Invac-
are wheelchairs have NOT been designed or tested as a seat for any kind of weight training. If
occupant uses said wheelchair as a weight training apparatus, INVACARE SHALL NOT BE LIABLE
FOR BODILY INJURY AND THE WARRANTY IS VOID.
WEIGHT LIMITATION
The Pronto™ M6 model has a weight limitation of 250 lbs.
WARNING
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POS-
SIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.
ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE SOURCES
Powered wheelchairs and motorized scooters (in this text, both will be referred to as pow-
ered 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 cellular phones. The inter-
ference (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, 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 powered wheelchair model as shipped, with the INT/DL40i Non-Pro-
grammable (NP) electronics, has an immunity level of unknown.
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 appar-
ent and exposure is unavoidable. However, we believe that by following the warnings
listed, 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, cellular telephones, and other personal
communication devices. **NOTE: Some cellular telephones and similar devices trans-
mit signals while they are ON, even when not being used;
2) Medium-range mobile transceivers, such as those used in police cars, fire trucks, am-
bulances, and taxis. These usually have the antenna mounted on the outside of the
vehicle; and
3) Long-range transmitters and transceivers, such as commercial broadcast transmit-
ters (radio and TV broadcast antenna towers) and amateur (HAM) radios.
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers,
AM/FM radios, TV sets, CD players, 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
powered wheelchair.
