Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
Note 3: The ISM (industrial, scientific, and medical) bands between 0,15 MHz 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.
Note 4: Evaluated for immunity to proximity fields from RF wireless communication equipment per IEC 60601-1-
2:2014 Table 9.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which SV2 is used exceeds the applicable RF
compliance level above, SV2 should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating SV2.
b Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and SV2
SV2 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of SV2 can help prevent electromagnetic interferences by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and SV2 as recommended below,
according to the maximum output power of the communications equipment.
