Electromagnetic Compatibility
This product complies with the requirements of
applicable standards for electromagnetic
compatibility (EMC). However, medical electrical
equipment such as the
Sara Plus
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.
Guidance and manufacturer’s declaration: electromagnetic emissions (EMI)

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

CISPR 11
Class B
This equipment is suitable for use in all establishments, in-
cluding domestic establishments and those directly connected
to the public low voltage power supply network that supplies
buildings used for domestic purposes.

Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the
Sara Plus,
in-
cluding cables, than 1.0m, if the trans-
mitter’s output power rating exceeds
1W
(a)
Field strengths from fixed RF trans-
mitters, as determined by an electro-
magnetic site survey, should be less
than the compliance level in each fre-
quency range
(b)
Interference may occur in the vicinity
of equipment marked with this sym-
bol:
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 Plus
is used exceeds the applicable RF compliance level above,
the
Sara Plus
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 Plus
The
Sara Plus
is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer and user of the
Sara Plus
can help prevent electromagnetic interference by maintaining a minimum dis-
tance between portable and mobile RF communications equipment (transmitters) and the
Sara Plus
by maintaining a
distance of not less than 1 metre to any part of the
Sara Plus
, including cables, if the transmitter’s output power rating
exceeds 1W.
