a
In theory, the field strengths of stationary transmitters such as base stations for cell phones and mobile land
radio equipment, amateur radio stations, AM and FM radio and TV transmitters cannot be predicted accu-
rately. To assess the electromagnetic environment with respect to stationary RF transmitters, a site study of
the electromagnetic phenomena should be considered. If the field strength measured at the location where
the device is used exceeds the above compliance levels, the device must be monitored to verify proper func-
tion. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or re-
locating the ME equipment or ME system.
b
Field strengths should be less than 3 V/m for the 150 kHz to 80 MHz frequency range.
