marked with the
following symbol:
a. The PRM and ZWT are intended for use in the electromagnetic environment specified in the table.
The customer or the user sh
ould ensure they are used in such an environment.
b. These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
c. At 80 MHz and 800 MHz, the hig
her frequency range applies.
d. 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 theor
etically 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 PRM and ZWT are used exceeds the applicable RF
compliance level shown i
n the table, they should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the PRM and ZWT.
e. Over the frequency range
150kHzto80MHz,field strengths should be less t han 3 V/m.
