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-1000S Plus scooter]
is used exceeds the applicable RF compliance level above, the [SW-1000S
Plus scooter] should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
reorienting or relocating the [SW-1000S Plus scooter].
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-1000S Plus scooter]
The [SW-1000S Plus scooter] is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the [SW-1000S Plus scooter] can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the [SW-1000S Plus scooter]
as recommended below, according to the maximum output power of the
communications equipment.
