Portable and mobile communications
equipment should be separated from the
RS 221 incl. the cables by no less than the
distances calculated/listed below.
Recommended distances:
d = 0,35 √P
d = 0,35 √P
80 MHz to 800 MHz
d = 0,70 √P
800 MHz to 2,5 GHz
where „P“ is the max. power in watts (W)
and D is the recommended separation
distance in meters (m).
Fieldstrengthsfromxedtransmitters,as
determined by an electromagnetic site (a)
survey, should be less than the compli-
ance level (b).

used exceeds the above compliance level, the ATMOS A / C 161 / 261 Aspirator is to be observed to verify
the intended use.
If abnormal performance characteristics are noted, additional measures might be necessary, e. g. a changed
arrangement or another location for the device.
