Recommended separation distances between portable and mobile RF communications equipment and
the hyperion X9.
The hyperion X9 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the hyperion X9 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitter) and
the hyperion X9 as recommended below, according to the maximum output power of the communications
equipment.

100 12 12 23
For transmitters rated at the maximum output power not listed above, the recommended separation distance d in
meters (m) can be estimated the equation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note:
(1) At 80MHz and 800MHz, the separation distance for the higher frequency range applies.
(2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
1.8.9. PROTECTION AGAINST RADIATION
The system is an X-ray device. As such, it exposes the patient and the operators to the risks deriving from
radiation. It must be used in compliance with the safety regulations set out in the radiation protection standards
in force in the country of use. Some requirements are listed below:
- Start X-ray emission only from the control room. The radiation room must be adequately shielded (if
required by regulations currently in force in the country of use).
- Make sure the radiation room’s doors are closed before starting the examination.
- Only the patient shall be present in the radiation room during X-ray emission. If the presence of a person
is necessary during the examination (for example to help patients who are not self-sufficient), personal
equipment must be used to protect the individual against scattered radiation. In any case, no body parts
should be exposed directly to the X-rays. Patients may not be assisted by pregnant women or minors.
- During the system initialisation procedure, no one may stay in the examination room and the doors must
be closed. The room must be manned on the outside by authorised personnel until projection is complete.
- Make sure that you do not release the X-ray emission button prematurely. Note that radiation may be
emitted numerous times during an exposure cycle. Wait until the exposure cycle is complete.
- The following points must always be observed:
- During exposure, keep a distance of at least 2 metres from the X-ray source. For installations in
Canada, the required distance is 3 metres.
- Anyone not directly involved with the patient should be outside the room where the examination is
carried out or stand behind a lead shield or lead glass panel during exposure.
- Make sure that the operator can communicate verbally and visually with the patient.
- If required, use a dosimeter for personal monitoring.
1.8.10. APPLIED PARTS
The parts that, during standard use, necessarily come into contact with the patient in order for the device to carry out
its functions correctly, are: chinrest, bite piece and hygienic protections, headrest, handles, ceph nasion and earpiece
protections.
The non-applied parts that may come into contact with patient are the external covers and the patient arm.
