12.2 Information on electromagnetic compatibility (EMC)
Electromagnetic interference immunity
The RadiForce LS580W was tested with the following compliance levels in accordance with the test
requirements for professional healthcare facilities, as established in IEC/EN 60601-1-2.
Customers and users of the monitor have to ensure that the monitor is used in such an environment.

Note: Guidelines with respect to line-based interference due to RF fields or electromagnetic RF
fields may not apply in all situations. Absorption and reflection by structures, objects, and people im-

a)
The field strengths of fixed transmitters, for example the base station for cordless and mobile tele-
phones, radio, land mobile radio, ham radio, and television cannot be determined precisely in ad-
vance. To evaluate the electromagnetic environment using fixed transmitters, an electromagnetic lo-
cation measurement should be included. If the measured field strength in the environment where the
device is used exceeds the applicable RF compliance level, observe the monitor to ensure its proper
operation. If improper operation is observed, in some circumstances additional measures may be
necessary, such as reorienting or repositioning the device.

rms is determined using the formula for calculating the
frequency of the transmitter.

3 V/m
d = 2 √P, ISM bands between 150 kHz and 80 MHz
d = 3.5/3 √P = 1.2 √P, 80 MHz to 800 MHz
d = 7/3 √P = 2.3 √P, 800 MHz to 2.7 GHz
In this case, "P" stands for the measured maximum
nominal output power in watts (W) of the transmitter
recommended by the transmitter manufacturer, and
"d" for the recommended minimum distance in me-
ters (m).
