Separation distances
The Aoralscan 2 is intended for use in the electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Aoralscan
2 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
Aoralscan 2 as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated a maximum output power not listed above, the
recommended separation distance
d
in meters (m) can be estimated using 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 80 MHz and 800 MHz, the separation distance for the higher frequency
range applies.
NOTE 2:
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
The medical electrical equipment is suitable for the professional healthcare
environment per 60601-1-2:2014. It is suitable for use in physician offices, clinics,
hospitals, and other professional healthcare environments except near HF surgical
equipment and the RF shielded room of an ME system for magnetic resonance
imaging or other environments where the intensity of electromagnetic disturbances is
high.
The clinical environments where the device can be used include physician offices,
clinics, hospitals, and clinical point-of-care for diagnosis of patients except
environments where the intensity of electromagnetic disturbances is high.
