a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) te
lephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcas
t 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 mea
sured field strength in the location in which the EUT is used exceeds the applicable RF comp
liance level above, the EUT should be observed to verify normal operation. If abnormal perfo
rmance is observed, additional measures may be necessary, such as re-orienting or relocating
the EUT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V
/ m.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment
and
the BM5 system.
The BM5 system is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the BM5 system can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the BM5 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 separa
tion distance (d) in meters (m) can be estimated using the equation applicable to the frequenc
y of the transmitter, where P is the maximum output power rating of the transmitter in watts
(W) according to the transmitter manufacturer.
