This
Diagnostix
TM
Instrument
model is intended for operation in the electromagnetic environment specified below.
The customer or the user of this
Diagnostix
TM
instrument
should ensure that it is used in such an environment.
Compliance
Level
Portable and mobile radio
equipment should not be used
within a distance from the
Diagnostix
TM
instrument, including
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
ì
P
d = 1.2
ì
P 80 MHz to 1000 MHz
d = 2.3
ì
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
Interference is possible in the
vicinity of equipment marked with
the following symbol
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
at the location of the Diagnostix
TM
Instrument exceeds the compliance level indicated above, then the Diagnostix
TM
Instrument must be
monitored with regard to its normal operation at each place where it is used. If unusual performance characteristics are observed, additional
measures such as re-alignment of the Diagnostix
TM
Instrument or its removal to another place may be necessary.
b.
In the frequency range of 150 kHz to 80 MHz, the field strength should be smaller than 3 V/m.
