myray hyperion Instructions De Service page 35

● The criteria adopted to define hyperion immune to EMC disturbances are:
- Communication between hyperion and the computer is never interrupted;
- The data exchanged between hyperion and the computer are never corrupted (image integrity);
- hyperion does not emit uncontrolled x-rays;
- hyperion x-ray emission values (kV, mA and exposure time) fall within the tolerances given in paragraph "tech-
nical data – radiological data" in this manual.

Electromagnetic environment – rec-
ommendations
hyperion uses RF energy only for in-
ternal functions. Therefore its RF emis-
sions are very low and do not cause in-
terferences to other nearby equipment.
hyperion can be used in residential in-
stallations (or connected to the public
low voltage power supply system for
household use) taking the following
precautions: hyperion may be used
only by properly trained dental profes-
sionals or paramedics. hyperion may
cause radio interferences and disturb
nearby equipment. Counter-measures
may be required such as re-directing
or moving hyperion or shielding the in-
stallation room.

Wooden, concrete or ceramic
tile floors may be used. If the
floor is covered in synthetic
material, the relative humidity
must be more than 30%.
