Technical Information
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The LLVS is intended for use in the electromagnetic environments
specified below. The customer or the user of the LLVS should assure it is
used in such an environment.
Immunity
Test
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 Vrms
IEC 61000-4-3
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.

IEC 60601
Test Level
Compliance
Level
Portable and mobile RF
communications equipment
should be used no closer to any
part of the LLVS, including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommended separation
distance
d =
3 Vrms
d =
3 V/m
d =
Where P is the maximum output
power rating of the transmitter
in watts (W) according to the
transmitter manufacturer and d
is the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey,
should be less than the compliance
level in each frequency range.
Interference may occur in the
vicinity of equipment marked
with the following symbol:
