Technical Specifications and Conformity
Recommended safety distances between portable and mobile RF communications equip-
ment and the MASTERPULS
®
ONE
The MASTERPULS
®
ONE is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The operator or the user of the MASTERPULS
®
ONE an help prevent
electro-magnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the MASTERPULS
®
ONE, as recommended below,
ac-cording to the maximum output power of the communications equipment.

In the case of transmitters that do not have their rated power specified in the table above, the dis-
tance can be calculated using the equation for the column in question, where P is the rated power
of the transmitter in watts [W] according to the information of the transmitter manufacturer.
NOTE 1:
An additional factor of 10/3 was used when calculating the recommended safety distance of trans-
mitters in the frequency range from 80 MHz to 2.7 GHz. The purpose of this was to reduce the
likelihood of a malfunction occurring in the event of a mobile/portable communications device be-
ing inadvertently brought into the patient area.
NOTE 2:
These guidelines may not apply in all situations. The propagation of electromagnetic waves is af-
fected by absorption and reflection from buildings, objects and people.
