Note 1: The guidance may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.
a) Field strengths from fixed transmitters, such as base stations for radio (celluar/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 transmit-
ters, an electromagnetic site survey shall be considered. If the measured field strength in the location in which the aScope 3 system is used exceeds the
applicable RF compliance level above, the aScope 3 system shall be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the aScope 3 system unit.
b) Over the frequency range 150kHz to 80MHz, field strengths shall be less than 3V/m
Recommended Separation Distances Between Portable and Mobile RF Communication Equipment and aScope 3 system.
The aScope 3 system is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The user of the aScope 3
system can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters and the aScope 3 system as recommended below, according to the maximum output power of the communication 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.
