NOTE 1At 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 reflection from structures, objects and people.
a The ISM(industrial, scientific and medical) bands between 0,15 MHz and 80 MHz
are 6,765 MHzto6,795 MHz;13,553 MHz to 13,567 MHZ;26,957 MHz to 27,283
MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz
and 80 MHz are 1,8 MHz to 2,0 MHz,3,5 MHz to 4,0 MHz,5,3 MHz to 5,4 MHz,7
MHz to 7,3 MHz,10,1 MHz to 10,15 MHz,14 MHz to 14,2 MHz,18,07 MHz to 18,17
MHz,21,0MHz to 21,4MHz,24,89 MHz to 24,99 MHz,28,0 MHz to 29,7 MHz and
50,0 MHz to 54,0 MHZ.
b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz
and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the
likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 has been incorporated into the formulae used in
calculating the recommended separation distance for transmitters in these
frequency ranges.
c 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
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 device is used exceeds the applicable RF compliance level
above, the device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
re-orienting or relocating the device.
d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.

WARNINGS!
· This device should not be used in the vicinity or on the top of other
electronic equipment such as cell phone, transceiver or radio
control products. If you have to do so, the device should be
observed to verify normal operation.
· The use of accessories and power cord other than those specified,
with the exception of cables sold by the manufacturer of the
equipment or system as replacement parts for internal components,
may result in increased emissions or decreased immunity of the
equipment or system.
· Use of this equipment adjacent to or stacked with other equipment
should be avoided because it could result in improper operation.
· Use of accessories, transducers and cables other than those
specified
or provided by the manufacturer of this equipment could result in
increased electromagnetic emissions or decreased
electromagnetic
immunity of this equipment and result in improper operation.
· Portable RF communications equipment (including peripherals
such
as antenna cables and external antennas) should be used
no closer
than 30 cm (12 inches) to any part of the device,including cables
specified by the manufacturer. Otherwise, degradation of the
performance of this equipment could result.
· Portable and mobile RF communications can affect the device.
The device needs special pre-cautions regarding EMC according to
the EMC information provided in the accompany documents.
· Do not use the devices in the MR environment.
· The Operator should not use the system and should inform the
customer service, if the ESSENTIAL PERFORMANCE is lost or
degraded due to EM DISTURBANCES.
· PRECAUTION: The performance of the device may be degraded
should one or more of the following occur:
- Operation outside the manufacturer’s stated temperature and
humidity range.
- Storage outside the manufacturer’s stated temperature and
humidity range.
- Mechanical shock (for example, drop test) or degraded sensor.
- Patient temperature is below ambient temperature.
