Appendix
40
Electromagnetic emitted interference according to IEC 60601-1-2
The CardioMessenger is suitable for operation in the indicated electromagnetic environment.

The customer and/or operator of the CardioMessenger should make sure that it is used in an electro-
magnetic environment as described below.

Same as test level The minimum distance of the CardioMessenger from portable and mobile
radio devices, including the cables, should correspond to the recommended

safe distance that is calculated according to the equation for the suitable
transmission frequency. Recommended safe distance:

D= 2,34 for 800 MHz to 2.5 GHz with P as the nominal output of the
transmitter in Watts (W) according to the information from the transmitter
manufacturer, and d as the recommended safe distance in meters (m).
The field strength of stationary transmitting devices should be measured on
site
a)
and must be lower than the compliance level at all frequencies
b)
.
Interference can be generated when the CardioMessenger is close to
devices that have the following warning sign:
Note: The higher frequency range applies at 80 MHz and at 800 MHz.
Note: These guidelines may not be applicable in all cases. The spread of electromagnetic waves is influenced by absorption and reflection from
buildings, objects, and humans.
