The Laerdal Suction Unit (LSU) is intended for use in the electromagnetic environment specified below.The customer or the user of the
LSU should assure that it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the LSU,
including cables, than the recommended separation
distance calculated from the equation applicable to
frequency of the transmitter.
Recommended separation distance
d=1.2 •P
d=0.35•P 80 MHz to 800 MHz
d=0.7•P 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 deter-
mined by an electromagnetic site surveya, should be
less than the compliance level in each frequency
rangeb.
Interference may occur in the vicinity of equipment
marked with the following symbol:
Guidance and manufacturer’s declaration – electromagnetic immunity
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 LSU is used exceeds the applicable RF compliance level above, the LSU
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the LSU.
b.
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
