Recommended safety distances between portable and
mobile HF communications equipment and the D-ACTOR
®
200
The D-ACTOR
®
200 is intended for use in an electromagnetic environment in which radiated HF
disturbances are controlled. The customer or the user of the D-ACTOR
®
200 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile HF
communications equipment (transmitters) and the D-ACTOR
®
200 as recommended below, according to
the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended safety distance can
be estimated using the equation applicable to the frequency of the transmitter, where P is the rated power
of the transmitter in watts [W] according to the transmitter manufacturer.
NOTE 1
An additional factor of 10/3 was used for calculating the recommended safety distance of transmitters in
the frequency range from 80 MHz to 2.5 GHz in order to reduce the probability that a mobile/portable
communications device brought into the patient area might inadvertently lead to a malfunction.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
