Note: These guidelines may not apply in all situations. The propagation of electromagnetic quantities is
affected by absorptions and reflections of buildings, objects, and persons.
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 of the stationary
transmitters, a site survey should be considered. If the measured field strength in the location at which
the device is used exceeds the above conformity levels, the device should be observed to verify normal
operation. If unusual performance characteristics are observed, additional measures may be necessary,
such as a modified orientation or a different location for the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – guidelines
Portable and mobile RF communications
equipment should be used no closer to any
part of the KARL STORZ AIDA
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.

Where P is the nominal power of the
transmitter in watts [W] according to the
information provided by the manufacturer of
the transmitter and d is the recommended
separation distance in meters [m].
The field strength of stationary transmitters
at all frequencies on site a should be,
according to a study, less than the
conformity level b .
