EPIC II CRITICAL CARE BED (CONTINUED)
The Epic II Critical Care Bed is suited for use in the electromagnetic environment specified below. The
customer or the user of the Epic II Critical Care Bed should assure that it is used in such an environment.
Immunity Test
IEC 60601 Test Level
Conducted
RF
150 kHz to 80 MHz
IEC 61000-4-6
Radiated RF
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 Epic II Critical Care Bed is used
exceeds the applicable RF compliance level above, the Epic II 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 Epic II Critical Care Bed.
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.

Electromagnetic Environment - Guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Epic II Critical Care Bed, including cables,
than the recommended separation distance
calculated from the equation appropriate for the
frequency of the transmitter.
Recommended Separation Distance
d=1,2
d=1,2
80 MHz to 800 MHz
d=2,3
800 MHz to 2,5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation diestance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survery,
should be less than the complliance level in
each frequesncy range.
b
Interference may occur in the vicinity of
equipment marked with the following symbol:
