Portable and mobile RF communications 
equipment should be used no closer to 
any part of the CXDI-55G, including 
cables, than the recommended separation 
distance calculated from the equation 
applicable to the frequency of the trans-
mitter.
Recommended separations distance
where P is the maximum output power rat-
ing of the transmitter in watts (W) accord-
ing to the transmitter manufacturer and d 
is the recommended separation distance 
in metres (m).
Field strengths from fixed RF transmitters, 
as determined by an electromagnetic site 
survey

ance level in each frequency range

.
Interference may occur in the vicinity of 
equipment marked with the following sym-
bol:
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 reflections from structures, object and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
phones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast can-
not be predicted theoretically with accuracy. To assess the electromagnetic environment due to 
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field 
strength in the location in which the CXDI-55G is used exceeds the applicable RF compliance level 
above, the CXDI-55G should be observed to verify normal operation. If abnormal performance is 
observed, additional measures may be necessary, such as reorienting or relocating the CXDI-55G.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
