Instructions for use DEXIS CariVu 3-in-1 by KaVo
9 Information concerning the electromagnetic compatibility in accordance with EN IEC 60601-1-2 | 9.3 Resistance
to electromagnetic interference
9.3 Resistance to electromagnetic interference
The DEXIS CariVu 3-in-1 by KaVo is designed for use in an environment of the
kind specified below. The customer or the user of the DEXIS CariVu 3-in-1 by
KaVo should ensure that the device is used in an environment of the specified
type.

devices should not be used at a

cables than the recommended
safe clearance calculated using
the appropriate equation for the
emission frequency.
Recommended safe distance:
d = 1.17

for 80 MHz to 800
MHz
d= 2.33
P
for 800 MHz to 2.5

where P is the maximal nominal
power of the transmitter in watts
(W) as specified by the transmit-
ter manufacturer and d is the
recommended safe clearance in
meters (m).
b
The field strength of stationary
wireless radio transmitters as
measured locally
c
should be
lower than the conformance level
at all frequencies.
d
Interference is possible in the
vicinity of devices bearing the
following icon.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not be applicable in every case. The spread of
electromagnetic waves is absorbed and reflected by buildings, objects and peo-
ple.
a
The ISM frequency bands (for industrial, scientific, and medical applications)
between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to
13.567 MHz; 26.957 MHz to 27.283 MHz, and 40.66 MHz to 40.70 MHz.
b
The compliance levels in the ISM frequency bands between 150 kHz and 80
MHz and in the frequency range from 80 MHz to 2.5 GHz are intended to re-
duce the probability of mobile/handheld communications facilities causing inter-
ference when they are inadvertently introduced into the patient area. For this
reason, the additional factor of 10/3 is applied in the calculation of the recom-
mended safe clearances in these ranges of frequencies.
c
The field strength of stationary transmitters, such as, e.g. base stations of mo-
bile phones and mobile terrestrial radio devices, amateur radio stations, AM and
FM radio and television transmitters, cannot be determined exactly based on
theoretical considerations. A site study should be considered to determine the
