Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines 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 (cellular/cordless) telephones and land mobile radios,
amateur radios, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment due to the fixed RF transmitters, an electromagnetic site survey should be considered.
If the measured field strength in the location in which the device or system is used exceeds the applicable RF compliance
level above, the device or system should be observed to verify normal operation. Should unusual performance features be
observed, additional measures (such as change in orientation or change of site of the system) may be necessary.
b
Over the frequency range of 150 kHz to 80 MHz the field strength should be less than 3 V/m.

Electromagnetic environment - guidance
This unit uses a technology that is based on elec-
tron beam deflection. Therefore, a magnetic field in
the vicinity must be reduced to the compliance
level, e.g. through design or shielding.
Power frequency magnetic fields should be at
levels characteristic of a typical commercial or hos-
pital environment.
Portable and mobile RF telecommunications equip-
ment should be used no closer to any part of the
system (including cables) than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2 P
d = 1.2 P
for 80 MHz to 800 MHz
d = 2.3 P
for 800 MHz to 2.5 GHz
Where P is the maximum output power rating of
the transmitter in watts (W) according to the trans-
mitter manufacturer and d is the recommended
separation distance in meters (m).
Field strengths from fixed RF transmitters, as deter-
mined by electromagnetic site survey
less than the compliance level in each frequency

range.
