Instructions for use DIAGNOcam 2170 U
9 Information concerning the electromagnetic compatibility according to EN IEC 60601-1-2 | 9.4 Recommended
safe distance between portable and mobile HF telecommunications equipment and the treatment unit
characteristics are observed, additional measures may be required, such as,
e.g., changing the orientation or using a different location for the DIAGNOcam
2170 U.

9.4 Recommended safe distance between portable and
mobile HF telecommunications equipment and the
treatment unit
The DIAGNOcam 2170 U is intended for use in an electromagnetic environment
in which the HF interference parameters are controlled. The customer or the
user of the DIAGNOcam 2170 U can help prevent electromagnetic interference
by maintaining the minimum distance between portable and mobile HF tele-
communications devices (transmitters) and the DIAGNOcam 2170 U depending
on the output of the communication device as indicated below.
Safe distance depending on the transmission frequency:
Rated maximum out-
put power of trans-
mitter in W 150 kHz to 80 MHz
d=1.17
P m
80 MHz to 800 MHz
d=1.17
P m
800 MHz to 2.5 GHz
d=2.33
P m
0.01 0.1 0.1 0.2
0.1 0.4 0.4 0.7
1 1.2 1.2 2.3
10 3.7 3.7 7.4
100 11.7 11.7 23.3
For transmitters whose maximum rated power is not included in the above
table, the recommended safe distance d in metres (m) can be calculated using
the equation for the respective column, where P is the maximum rated power
of the transmitter in Watts (W) as specified by the manufacturer.
NOTE: At 80 MHz and 800 MHz, the higher frequency range applies.
The spread of electromagnetic waves is absorbed and reflected by buildings,
objects and people.
