6. Guidance and manufacturer’s declaration – electromagnetic immunity
The ElectroFlex is intended for use in the electromagnetic environment specified below. The customer or the user of
the ElectroFlex should assure that it is used in such an environment.
Conducted RF 3V/ms 3V/m Portable and mobile RF communications equipment
IEC 61000-4-6 150kHz to should be used no closer to any part of the ElectroFlex,
80MHz including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.

Distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey, a
should be less than the compliance level in each
frequency range (b).
Interference may occur in the vicinity of equipment
marked with the following symbol:
At 80MHz and 800MHz, the higher frequency range applies.
These guidelines 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 a
ssess t
he 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 ElectroFlex is used exceeds the
applicable RF compliance level above, the ElectroFlex should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the ElectroFlex.
(b) Over the frequency range
150kHz t
o 80MHz, field strengths should be less than 3V/m.
7. Recommended separation distances between
portable and mobile RF communications equipment and the ElectroFlex
The ElectroFlex is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the ElectroFlex can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the ElectroFlex as recommended
below, a
ccording to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
At 80MHz and 800MHz, the separation distance for the higher frequency range applies.
These guidelines may not apply in all situat
ions. E
lectromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
