Special Conditions Of Use; Electromagnetic Interference (Emi) - Acekare YOMPER+ User Manual

1. Special conditions of use

Use on a steep slope : you have to lean forward so as not to tip back.
Mounting/Descending a Curb : you must stop the Yomper (press the main button) before going up or down a curb.
Use in 2-wheel mode : you must stop the Yomper (press the main button) before operating on 2 wheels. Without it, you risk tipping
backwards when the Yomper's motor hits the ground.
Off-road use : the Yomper may help you travel off-road. It may propel you slowly but allow forward travel regardless of the terrain.
However, we recommend that you be very careful when using the Yomper off-road. Indeed, few manual wheelchairs are suitable for
off-road use, especially those with smaller caster wheels at the front. Your caster wheels may become stuck on uneven ground causing you
to tip over, especially when powered by the Yomper.

Electromagnetic interference (EMI)

Interference comes from radio sources, for example: radio / TV transmitters, cell phones, walkie talkies etc. There are many sources of EMI
in your environment, some are preventable, others will not be visible. Electronic systems such as the Yomper are sensitive to strong EMI,
+ or -. These interferences can cause the Yomper to activate unintentionally or cause damage to the control system, potentially causing
breakdowns and costly repairs.
Every electric wheelchair or system of this type can withstand EMI to a certain point, also known as the level of 'immunity'. The higher the
level of immunity, the lower the risk of EMI. An immunity level of 20V / m provides sufficient protection for everyday sources. The Yomper
has been tested and resists up to 20V / m.
Even if it is equipped with a sufficient protection system, any modification of the wheelchair or the addition of accessories may affect this
immunity. Parts from other suppliers have unknown properties and their interaction with the Yomper has not been tested.
The electromagnetic energy becomes more intense as you get closer to the source. It is therefore recommended not to use the Yomper
near radio sources. We can distinguish 3 categories of EMI :
• Long-distance transmitters: sources for radios, commercial radio, antennas of TV station towers and amateur radios..
• Medium-range mobile transmitters: sources of radios, including radios used by emergency vehicles, tractors, taxis..
• Mobile transmitters: the waves are very weak: walkie talkies, CBs, mobile phones and other personal means of communication.
Cordless phones, MP3 or CD players, TV or AM / FM radios are safe.
If the Yomper turns on unintentionally, turn off the system and report the incident to Acekare Technical Service (indicate any source of EMI
that was nearby when the incident occurred).
