Portable and mobile RF communications equipment should

 

 

 

be used no closer to any part of the UP-DR80MD, including

 

 

 

cables, than the recommended separation distance

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.

aField 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 UP-DR80MD is used exceeds the applicable RF compliance level above, the UP-DR80MD should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the UP-DR80MD.

bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
