EMI Information
Electromagnetic Interference (EMI) From Radio Wave Sources
This product 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 powered bed to release its brakes, move by itself, or move in unintended directions. It can also permanently damage the powered bed's
control system. The intensity of the interfering EM energy can be measured in volts per meter (V/m). Each powered bed 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.
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 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).
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; and
WARNING
Charge battery through the controller. NEVER attempt to charge the battery by any other means.
Internal battery should be tested monthly.
CAUTION
IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF
ELECTROMAGNETIC INTERFERENCE ON THIS PRODUCT.
Some cellular telephones and similar devices transmit signals while they are ON, even when not being used.
