1.4 Interférences électromagnétiques (EMI)
Interferences come from radio sources, for exemple : radio/TV transmitters, mobile phones, walkie-talkies, etc.
There are numerous sources of EMI in our environment, some can be avoided, others are not visible. Electronic
systems such as the Yomper are sensitive to EMI, depending on their strength. These interferences may cause
the unintentional start of the Yomper or damages in the control system, potentially resulting in failures and
costly repairs.
Each electric wheelchair or system of this type can resist EMI up to a certain point, also known as the level of
‘immunity’. If the level of immunity is high, the risk of EMI is less important. A level of immunity of 20V/m
offers enough protection from everyday sources. The Yomper has been tested and resists up to 20V/m.
Even if it is equipped with a strong protection system, any alteration of the wheelchair or addition of
accessories may affect this immunity. Pieces coming from other suppliers have unknown properties and their
interaction with the Yomper hasn’t been tested.
Electromagnetic energy becomes more intense when you get closer to the source. Thus it is advised not to use
the Yomper close to radio sources. We can distinguish 3 categories of EMI :
• Long distance transmitters : radio sources, commercial radios, antennas of station TV towers and
amateur radios.
• Medium distance mobile transmitters : radio sources, including radios used by emergency vehicles,
tractors, taxis.
• Mobile transmitters : from which the waves are not very powerful : walkie-talkies, CBs, mobile
phones and other means of personal communication.
Wireless phones, MP3 or CD playes, TV or AM/FM radios present no risks.
If the Yomper starts unintentionnally, switch off the system and report the incident to the technical team (locate
any source of EMI close by when the incident occurred).
