NOTE 1: U

is the AC mains voltage prior to application of the test level
NOTE 2: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 3: The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765–6.795 MHz;
13.553–13.567 MHz; 26.957–27.283 MHz and 40.66–40.70 MHz.
NOTE 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
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 the Smartscope M5 is used exceeds
the applicable RF compliance level above, Smartscope M5 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Smartscope M5.
B) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
