Interference is possible in the vi‐

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) be‐
tween 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 reduce
the probability of mobile/handheld communications facilities causing interference
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 recommended safe
clearances in these ranges of frequencies.
c
The field strength of stationary transmitters, such as, e.g. base stations of mobile
phones and mobile terrestrial radio devices, amateur radio stations, AM and FM
radio and television transmitters, cannot be determined exactly based on theoreti‐
cal considerations. A site study should be considered to determine the electro‐
magnetic environment in terms of stationary transmitters. If the measured field
strength at the site, at which the DIAGNOcam 2170 is used, exceeds the compli‐
ance levels shown above, the DIAGNOcam 2170 should be monitored to demon‐
strate proper function. If any uncommon performance characteristics are ob‐
