EMI/RFI WARNING
RADIO WAVE SOURCES MAY AFFECT POWERED MOBILE VEHICLE CONTROL.
Electromagnetic (EMI) or Radio Frequency Interference (RFI) refers to the effects that outside sources of
such energy might have on the control systems of your mobility vehicle. The interference from these
sources could cause the vehicle to release its brakes, move by itself, and/or cause damage to the mobility
vehicle controller.
The sources of EMI/RFI can be broadly classified into three types:
• Handheld portable transceivers with antenna mounted directly on the transmitting unit. Examples
include: citizens band radios (CB), “walkie talkies”, security, fire and police transceivers, cellular
telephones, and other personal communication devices.
• Medium range mobile transceivers. These usually have the antenna mounted outside of a vehicle
or a building. Examples include: police, fire, ambulance and taxi receivers.
• Long range transmitters and receivers, such as commercial broadcast transmitters (radio and TV
broadcast antenna towers) and amateur (HAM) radios.
Note: So far as we know, other types of handheld devices, such as cordless phones, laptop
computers, AM/FM radios, TV sets, CD players and cassette players and small appliances such
as electric shavers and hair dryers are not likely to cause EMI/RFI problems to your mobility
vehicle.
SAFETY PRECAUTIONS
The following are some precautions you can take to reduce the risk of a mobility vehicle from being affected
by EMI/RFI.
1. Do not turn on or use hand held personal communication devices, such as citizens band radios
(CB) and cellular phones while your vehicle is turned on.
2. Be aware of nearby transmitters, such as TV or radio stations and try to avoid coming close to them.
3. Be aware that adding accessories and/or components, or modifying your mobility vehicle in any
way, may change its EMI/RFI resistance level, thus making it more susceptible to interference from
radio wave sources.
4. Turn off your mobility vehicle by removing the key from the key switch when you are getting onto or
off of your mobility vehicle and never leave the key in the key switch of an unattended mobility
vehicle.
5. Report all incidents of unintended movement or unexpected brake releases to Zip’r Mobility.
