Electromagnetic Immunity for Non Life-Supporting System
The R221/A - R221/A DHHS collimator is intended for use in the electromagnetic environment specified below. The customer
or the user of the collimator should assure that it is used in such an environment.
Immunity Test IEC 60601 Test

Environment
Portable and mobile RF
communications equipment should be
used no closer to any part of the R221/
A - R221/A DHHS, including cables,
then the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended Separation Distance
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2,5 GHz
3 V/m d=1.2 √P
80 MHz to 800MHz d=2.3
√P
800 MHz to 2.5GHz
Conducted RF
IEC 61000-4-6
3 V/m
150 kHz to 80 GHz
3 V d= 1.2 x √P
Where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation distance in
metres (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey, should be
less than the compliance level in each
frequency range.
Interference may occur in the vicinity of
equipment marked with the following
