The quality of the mains
power should correspond
to that of a typical
business or hospital
environment. If the user
of the ARC PLUS
requires it to continue
operating even in the
presence of power
interruptions, it is
recommended to operate
the ARC PLUS from an
uninterruptible power
supply or a battery.
Note: U
T
is the AC supply voltage prior to the application of the test level.
Electromagnetic immunity (IEC 60601-1-2, Table 204)
The ARC PLUS is intended for operation in the electromagnetic environment described below. The
customer or user of the ARC PLUS should ensure that it is operated in such an environment.

Portable and mobile wireless devices should not be
used within the recommended protective distance from
the ARC PLUS and its cables, which is calculated using
the formula appropriate to the relevant transmission
frequency.
Recommended protective distance:
d = 0.35 × √P
d = 0.35 × √P for 80 MHz to 800 GHz
d = 0.35 × √P for 800 MHz to 2.5 GHz
where P is the nominal transmitter output in watts (W)
specified by the transmitter manufacturer and d is the
recommended protective distance in metres (m).
The field strength of stationary transmitters as
determined by on-site measurements
a
should be lower
than the compliance level
b
at all frequencies.
Interference is possible in the vicinity of
devices bearing the following symbol:

Note 1 The higher frequency range applies in case of 80 MHz and 800 MHz.
Note 2 These guidelines may not be usable in all cases. The propagation of electromagnetic waves
is influenced by absorption and reflection by buildings, objects and people.
a
It is not possible to accurately predict the field strength of stationary transmitters such as
base stations for mobile telephones and land mobile radios, amateur radio transmitters, AM
and FM radio broadcast transmitters and TV broadcast transmitters. An EMC site survey with
regard to stationary transmitters should be considered in order to determine the effect of their
electromagnetic transmissions. If the measured field strength at the location where the ARC
PLUS is used exceeds the aforementioned compliance level, the ARC PLUS should be
monitored to verify proper operation. If unusual behaviour is observed, additional measures
may be necessary, such as changing the orientation or location of the ARC PLUS.
b
The field strength should be less than 3 V/m over the frequency range of 150 kHz to 80 MHz.
