RF emissions
CISPR 11
Group 1
REAL Immersive System uses RF energy only for
its internal function. Therefore, its RF emissions are
very low and are not likely to cause any
interference
in nearby electronic equipment.

*REAL Immersive System is calibrated appropriately to detect movement in virtual reality space in relation to real space accurately and
precisely. Sensors will compute and display position at an accuracy of a 2 cm radius with respect to real space at a max distance of 75 cm
relative to the headset. Sensors will also reproducibly compute position at a maximum deviation of a 2 cm radius for repeated movements at a
max distance of 75 cm relative to the headset. Please note that accuracy and precision specifications contain limitations and are dependent
on certain factors such as the amount of metal near the system. For example, if the patient is in a metal wheelchair and cannot move to a
non-metal chair, reduction in accuracy and precision may occur.
