Guidance and manufacturer's declaration – electromagnetic immunity
The NuStep model T4r is intended for use in the electromagnetic environment specifi ed below. The customer or
the user of the NuStep model T4r should assure that it is used in such an environment.
IMMUNITY test IEC 60601 TEST
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2,5 GHz
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 refl ection from structures, objects and people.
a. Field strengths from fi xed 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 fi xed RF
transmitters, an electromagnetic site survey should be considered. If the measured fi eld strength in the
location in which the NuStep model T4r is used exceeds the applicable RF compliance level above, the
NuStep model T4r should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the NuStep model T4r.
b. Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.

Electromagnetic environment – guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the NuStep model T4r, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.

d = 2.3 800 MHz to 2,5 GHz
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 fi xed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in
a
each frequency range. b
