GUIDANCE AND MINDRAY DS USA, INC. DECLARATION - ELECTROMAGNETIC
IMMUNITY
The Gas Module 3 is intended for use in the electromagnetic environment specified below. The
customer or the user of the Gas Module 3 should assure that it is used in such an environment.

ENVIRONMENT - GUIDANCE
Portable and mobile RF
communications equipment should be
used no closer to any part of the
Gas
Module 3 , including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation
distance
Conducted RF
IEC 61000-4-6 3 Vrms
150 kHz to 80 MHz 3 Vrms d = 1.2 x
Radiated RF
IEC 61000-4-3 3 V/m
80 MHz to 2.5 GHz 3 V/m d = 1.2 x 80 MHz to 800 MHz
d = 2.3 x 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
recommended separation distance in
meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
a
should be
less than the compliance level in each
frequency range.
b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
NOTE: At 80 MHz and 800 MHz, the higher frequency range
applies.
NOTE: 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 the-
oretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an elec-
tromagnetic site survey should be considered. If the measured field strength in the location in which the
Gas Module 3 is used exceeds the applicable RF compliance level above, the Gas Module 3 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Gas Module 3.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
