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 reflection from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot 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
K-020
is used
exceeds the applicable RF compliance level above, the
K-020
should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the
K-020
.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Table 206
Recommended separation distances between
portable and mobile RF communications equipment and the
K-020
The
K-020
is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the
K-020
can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the
K-020
as recommended below, according to
the maximum output power of the communications equipment.
