INTOUCH® CRITICAL CARE BED - (CONTINUED)
The InTouch® Critical Care Bed is suited for use in the electromagnetic environment specified below . The
customer or the user of the InTouch® Critical Care Bed should ensure that it is used in such an environment .
IEC 60601
Immunity Test
Test Level
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 reflection
from structures, objects and people .
a
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 InTouch® Critical Care Bed is used exceeds the
applicable RF compliance level above, the InTouch® Critical Care Bed should be observed to verify normal operation .
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
InTouch® Critical Care Bed .
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m .

Electromagnetic Environment - Guidance
Level
Portable and mobile RF communications equipment should be
used no closer to any part of the InTouch® Critical Care Bed,
including cables, than the recommended separation distance
calculated from the equation appropriate for the frequency of
the transmitter .
Recommended Separation Distance
3 Vrms
3 V/m
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 metres (m) .
