Conducted disturbances induced by RF
IEC 61000-4-6
Note 1: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
a. Essential performance of the AIM System per IEC 60601 requirements is defined as auditory and electrical
stimulation within safe amplitudes.
b. 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 due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the AIM System is used
exceeds the applicable RF compliance level above, the AIM System should be observed to verify normal operation.
c. Over the frequency range 150 kHz to 80 MHz, field should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communi-
The AIM System is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the use of the AIM System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the AIM System as recommended below, according to the maximum
output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer.
