MANUFACTURER'S GUIDE AND DECLARATION - ELECTROMAGNETIC IMMUNITY
The scooters are intended for use in the following electromagnetic conditions.
IMMUNITY TESTS
conducted RF IEC
61000-4-6
radiated RF
IEC 61000-4-3
3 A/m
The client or user must ensure that it is used in these conditions.
TEST LEVEL IEC 60601
3Vrms From 150
kHz to 80 MHz
20 V/m From 80
MHz to 2.5 GHz
Magnetic fields at the mains
frequency should have the
typical characteristics of
3 A/m
a commercial or hospital
environment. (Applies both

ELECTROMAGNETIC
ENVIRONMENT – GUIDE
Portable and mobile RF
communications devices
should not be used near
any part of the scooters,
including the cables,
unless the recommended
separation distances
are observed, calculated
by the equation
applicable to the
transmitter frequency.
Recommended distances:
d=[3,5/V1]√P
from 0 Hz to 80 MHz
d=[3,5/E1]√P
from 80 MHz to
800MHz,
d=[7/E1]√P
from 800 MHz
to 2.5 GHz,
where "P" indicates the
maximum rated output
of the transmitter in
Watt (W) according
to the transmitter
manufacturer and "d"
is the recommended
separation distance
in metres (m). The
intensity of the field of
fixed RF transmitters,
as determined by an
electromagnetic survey
of the site, a could be
lower than the level
of conformity of each
frequency range. b There
may be interference
near devices with the
following symbol:
