Electromagnetic Compatibility (EMC)
This product complies with the requirements of
applicable standards for electromagnetic
compatibility (EMC). However, medical electrical
equipment such as the
Sara 3000
requires special
precautions regarding EMC and should be installed
and used in accordance with the information below.
Warning:
Wireless communications
equipment such as wireless computer
network devices, mobile phones, cordless
telephones and their base stations, walkie-
talkies, etc. can affect this equipment and
should be kept at least 1.5m away from
the equipment.

CISPR11
Group 1
This equipment uses RF energy only for its internal func-
tions. Therefore its RF emissions are very low and are
not likely to cause any interference in nearby electronic
equipment.

This equipment is suitable for use in all establishments,
including domestic establishments and those directly
connected to the public low voltage power supply net-
work that supplies buildings used for domestic purpos-
es.

Portable and mobile RF
communications equipment should
be used no closer to any part of the
Sara 3000,
including cables, than
1.0m, if the transmitter’s output
power rating exceeds 1W
(a)
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey, should
be less than the compliance level in
each frequency range
(b)
Interference may occur
in the vicinity of
equipment marked with
this symbol:
a) Field strengths from fixed transmitters, such as base stations for cellular/cordless telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be accurately predicted
theoretically. To assess the 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
Sara 3000
is
used exceeds the applicable RF compliance level above, the
Sara 3000
should be observed to verify normal
operation. If abnormal performance is observed. additional measures may be necessary.
b) Over the frequency range 150kHz to 80MHz, field strength should be less than 1V/m.
Recommended separation distances between portable and mobile RF communications equipment and the
Sara 3000
The
Sara 3000
is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer and user of the
Sara 3000
can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the
Sara 3000
by maintaining a distance of not less than 1 metre to any part of the
Sara 3000
, including
cables, if the transmitter’s output power rating exceeds 1W.
