Compass Owner’s Manual – Models GP600 SS, GP600 CC | Revised 052313 |
EMI/RFI
The rapid development of electronics, especially in the area of communications, has saturated our environment with electromagnetic (radio) waves that are emitted by television transmitters, cellular phones, citizen’s band radios (CBs), amateur radios (ham radios), wireless computer links, microwave transmitters, paging transmitters, etc. These electromagnetic (EM) waves are invisible and increase in strength the closer one gets to the source of transmission. When these energy waves act upon electrical devices and cause them to malfunction or to function in an erratic or uncontrolled manner, they are referred to as Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI).
EMI/RFI AND YOUR Compass™
All electrically powered vehicles, including power chairs are susceptible to EMI/RFI. This interference could result in abnormal, unintended movement of a power wheelchair.
Unintended movement or brake release could cause an accident or injury.
The FDA has determined that each make and model of power chair can resist EMI/RFI to a certain level. The higher the level of immunity, the greater the degree of protection from EMI/RFI measured in volts per meter (V/m). The FDA has also determined that current technology is capable of providing 20 V/m of immunity to EMI/RFI, which would provide useful protection against common sources of interference. This product has been tested and has passed an immunity level of 20 V/m.
EMI/RFI RECOMMENDATIONS
PROHIBITED! Do not turn on or use
♦Be aware of any nearby transmitters (radio, television, microwave, etc.) on your intended route and avoid operating your chair close to any of those transmitters.
♦Turn off the power if your Compass™ is going to be in a stationary position for any length of time.
♦Be aware that adding accessories or components or modifying your power chair may make it more susceptible to EMI/RFI.
♦If unintended movement or brake release occurs, turn your power chair off as soon as it is safe to do so.
♦Report all incidents of unintended movement or brake failure to your Golden representative or to Golden Technologies, Inc. at (800)
Turn off your power chair as soon as it is safely possible if unintended or uncontrollable motion occurs or if unintended brake release occurs.
