Note 1: At 80 MHz and 800 MHz, the higher value applies.
Note 2: These guidelines may not apply in all situations. The propagation of electromagnetic waves is influenced by reflection and absorption by
buildings, objects and people.
a. The field strength of stationary transmitters, such as base stations of wireless telephones and mobile field radio services, amateur radio
stations, AM and FM radio and television transmitters cannot be precisely determined theoretically in advance. In order to determine the
electromagnetic environment due to stationary HF transmitters, an investigation of the location is advisable. If the field strength determined

Environment Guidelines
Portable and mobile radio
equipment should not be used
within a distance from the
Diagnostix instrument, including
TM
cables, that is less than the
recommended safety distance as
calculated by the equation that is
appropriate for the transmission
frequency.
Recommended safety distance:
d = 1.2 P
d = 1.2 P 80 MHz to 1000 MHz
d = 2.3 P 1400 MHz to 2.5 GHz
Where P is the nominal power of
the transmitter in Watts (W) as
specified by the manufacturer of
the transmitter, and d is the
recommended safety distance in
meters (m).
The field strength of stationary
radio transmitters should be less
than the compliance level at all
frequencies as verified by an on-
site test a
