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 aected by absorption and reection

from structures, objects, and people.

a Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be

considered. If the measured eld strength in the location in which the Opal System is used exceeds the

applicable RF compliance level above, the Opal System should be observed to verify normal operation. If

abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the

Opal System.

b Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 10 V/m.
