F.5 Safe distances for non-life support devices (standard table 6)
The information is based on the requirements of EN 60601-1-2:2007 (IEC 3
rd
edition).
Recommended safe distances between portable and mobile HF communication devices and this device.
This product is designed to be operated in an electromagnetic environment in which radiated HF interference is controlled. The customer or user of this product can help to
prevent electromagnetic interference by maintaining minimum distances between portable and mobile HF communication systems (transmitters) and this product, as rec-
ommended below in accordance with the maximum output of the communication system.
Nominal output of the transmitter (W)
Safe distance according to transmission frequency (m)

For transmitters with a nominal output not listed in the table above, the distance
D
can be calculated in meters (m) using the equation for the respective column, in which
P
is the nominal output of the transmitter in watts (W)
NOTE 1: At 80 MHz and 800 MHz the higher frequency applies.
NOTE 2: To calculate the recommended safe distance of transmitters in the frequency range of 80 MHz to 2.7 GHz an additional factor of

was used to reduce the
probability of a mobile/portable communication device causing interference if inadvertently brought into the patient area.
These guidelines may not apply in all situations. Electromagnetic wave propagation is influenced by absorption and reflection of buildings, objects and people.
