• These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
• 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.
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 Model 297300000000 I I s s o o l l i i b b r r i i u u m m PE support
surface is used exceeds the applicable RF compliance level above, the Model 297300000000 I I s s o o l l i i b b r r i i u u m m PE support
surface should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the Model 297300000000 I I s s o o l l i i b b r r i i u u m m PE support surface.
b Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 Vrms.
