Recommended Separation Distances for Non-Life Supporting Equipment
Collimator R 221 ACS - R 221 ACS DHHS is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the collimator can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the collimator
as recommended below, according to the maximum output power of the communications equipment.

Separation Distance According to Frequency of Transmitter
(m)
150 kHz to 80 MHz
d= 1.2 x √ P
80 MHz to 800 MHz
d = 1.2 x √ P
800 MHz to 2,5 GHz
d 0 2.3 x √ P
0.01 0.12 0.12 0.23
0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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.
RO 556 Measuring Tape Removal
This option excludes the tape measure presence inside the collimator.
RO 570 Shutter position verified by encoders
Supplementary safety device to ensure correct positioning of shutters. It consists of two
encoders mounted on the collimator.
