NOTE 1: at 80 MHz and 800 MHz, apply the separation distance for the higher frequency band.
NOTE 2: these guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
a The intensity of the field for fixed transmitters, such as base stations for radio-telephones (cellulars and cordless)
and terrestrial mobile radios, amateur radio equipment, AM and FM radio transmitters and TV transmitters may
not be known precisely in theory. To establish an electromagnetic environment caused by fixed RF transmitters,
one must run an on-site electromagnetic inspection. If the field intensity measured in the place where Nefti
is used exceeds the applicable RF level of conformity indicated above, normal functioning
of the scooters must be monitored. If abnormalities are observed, supplementary measures
may be necessary, such as re-orientation or repositioning of the scooters.
b The field intensity over the frequency range from 150 kHz to 80 MHz should be less than 3 V/m.
Table 4
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE
The scooters are intended to operate in an electromagnetic environment in which RF disturbances are
under control. The client or user of the scooters can contribute to preventing EM interference by ensuring
a minimum distance between the mobile and portable RF communications devices (transmitters) and
the scooter battery charger during charging and the internal scooter devices during their operation as
indicated below, in relation to the maximum output power of the radio communication equipment.

For transmitters whose maximum rated output power is not listed above, the recommended separation distance
d, in metres (m), can be calculated using the equation applicable to the transmitter frequency, where P is the
maximum rated output power of the transmitter, in Watt (W), as given by the transmitter's manufacturer.
