NOTE 1 ： At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2 ： These guidance 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 [SW-1000Sscooter] is used
exceeds the applicable RF compliance level above, the [SW-1000Sscooter]
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or
relocating the [SW-1000Sscooter].
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m 。
Recommended separation distances between portable and mobile RF
communications equipment and the [SW-1000Sscooter]
The [SW-1000Sscooter] is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of
the [SW-1000Sscooter] can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the [SW-1000Sscooter] as
recommended below, according to the maximum output power of the
communications equipment.
