Right Motor Fault – usually indicates a poor connection.
Check that the motor cables are not loose or disconnected.
If the above do not clear the fault, please contact your Magic Mobility dealer

Low Batteries
Charge the batteries
Check the battery leads and connections. Also check the fuse has not blown
(section 5.4).
If the above do not clear the fault, please contact your Magic Mobility dealer

Check the all electronic leads for damage
Make sure the hazard lights (if applicable) are turned off then turn the DX2
power off then back on again.
If the above do not clear the fault, please contact your Magic Mobility dealer

The motors have been at their current limit for too long.
Turn the DX2 system off and let the motors cool down. If you are attempting a
steep incline; seek an alternate route.

10.6 Electromagnetic Interference (EMI) From Radio Wave Sources
Powered Wheelchairs 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 wheelchair to release its
brakes, move by itself, or move in unintended directions. It can also permanently damage the
powered wheelchair’s control system. The intensity of the interfering EM energy can be
measured in volts per meter (v/m). Each powered wheelchair 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.
This powered wheelchair model as shipped, with no further modification, has an unknown
immunity. 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,
