d= 1.2 √P
where P is the transmitter's
rated power in watts (W) as
specified by the transmitter
manufacturer and d is the
recommended separation
distance in meters (m).
The field strength of
stationary radio transmitters
is lower than the
compliance level
b
at all
frequencies according to an
on-site investigation
a.
There is a possibility of
interference in the
surroundings which have
the following pictogram:
NOTE 1: At 80 MHz, the higher value applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic wave propagation is affected by absorption and
reflection from buildings, objects and people.
a The
field strength of stationary transmitters, such as base stations of radiotelephones and land mobile services, amateur
stations, AM and FM radio and television transmitters, cannot be predicted theoretically with accuracy. To determine the
electromagnetic environment and consequence of stationary RF transmitters, a site survey is recommended. If the
determined field strength at the location of the Kröber O2 exceeds the compliance level specified above, the Kröber O2
must be observed with respect to its normal operation at any application site. If unusual performance characteristics are
observed, it may be necessary to take additional measures, such as reorienting or relocating the Kröber O2.
b
Over the frequency range from 150 kHz to 80 MHz, the field strength is less than 3 V/m.
