NOTE : UT is the nominal value of the power voltage applied during the test.
NOTE 1 : At 80 MHz and 800 MHz, the higher frequency band applies.
NOTE 2 : These recommendations may not apply in all situations. The propagation of electromagnetic waves is modified by absorption and reflection due to structures, objects and people.
a The field level of immobile transmitters, such as radio telephone base stations (cellular and cordless) and mobile terrestrial radio systems, amateur radio systems, AM/FM radio
communication systems, and TV systems cannot be evaluated theoretically with precision. To ascertain the electromagnetic environment due to immobile RF transmitters, a site
measurement must be performed. If a field level measured within the environment in which this camera is used exceeds the above applicable compliance levels, check that this camera
operates in a satisfactory manner. If abnormal operation is observed, additional measurements should be taken, such as reorientation or relocation of the reference system.
b Outside the frequency band of 150 kHz to 80 MHz, the field level should be less than 3 V/m

Electromagnetic environment - Guide
The fl oor should be in timber, concrete or tiling. If the fl oor is
covered with a synthetic material, the relative humidity should
be at least 30%.
The quality of the main power supply should be that of a typical
commercial or hospital environment.
Not applicable
Not applicable
The magnetic fi eld at the network frequency should be at a
level characteristic of a location within a typical commercial or
hospital environment.
Portable and mobile RF communication devices must not be
used at a distance from this camera – including cables – that
is less than the recommended separation distance calculated
using applicable formulae according to the transmitter's
frequency.
Recommended separation distance
d = 1,16 P
d = 1,16 P 80 MHz à 800 MHz
d = 2,33 P 800 MHz à 2,5 GHz
In which P is the maximum output power of the transmitter, in
Watts (W), assigned by the manufacturer of the transmitter and
the recommended separation distance (d) in meters (m).
The fi eld levels emitted by immobile RF transmitters – which
are to be established by an electromagnetic measurement
at the site – must be lower than the compliance level in each
frequency band.
Interference can occur nearby devices bearing the following
