Disturbances are possible
close to devices that have
the following symbol.
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 electro‐
magnetic waves is absorbed and reflected by buildings, objects and people.
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 conformance levels in the ISM frequency bands between 150 kHz and 80 MHz
and the frequency range of 80 MHz and 2.5 GHz are intended to reduce the probabili‐
ty that mobile and portable communications equipment will produce disturbances
when they are unintentionally brought near the patient. For this reason, the additional
factor of 10/3 is used when calculating the recommended safe distances within these
frequency ranges.
c The field strength of stationary transmitters such as base stations of mobile tele‐
phones and land mobile radio devices, amateur radio stations, AM and FM, radio and
television broadcasters cannot be theoretically predetermined. To determine the elec‐
tromagnetic environment of stationary transmitters, a study of the location should be
considered. When the measured field strength at the site where the DIAGNOdent pen
type 2190 is used exceeds the above conformance level, the DIAGNOdent pen type
