o Keys : 15 cm
o While using the MPOD for measurement or calibration (see further below), see to it
that there isn’t any object likely to disturb measurements (ferrous objects, watches,
mobile phone…)
o MPOD should be used far from motorized chairs or beds.
o Only small magnets are accepted in the same room (i.e. whiteboard magnet), but
must be kept far from the MPOD (>50 cm), as they might cause a serious decrease in
the systems accuracy.
o DO NOT TO PUT THE MPOD IN CONTACT WITH A MAGNET AS IT WILL MAKE IT
PERMANANTLY USELESS.
o The presence of strong magnetic field generating machines (like MRI) is not adapted
to the use of MPOD™.

MotionDevTool v2.0.4 software automatically checks if this condition is verified during recording of the
movement signature. An alarm is emitted in case of magnetic disturbance. If there is no alarm, the user is
under desired conditions.
