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 propa-
gation is affected by absorption and reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellu-
lar/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 electro-
magnetic site survey should be considered. If the measured field strength in the
location in which the AGU NS19 nasal aspirator is used exceeds the applicable RF
compliance level above, the AGU NS19 nasal aspirator should be observed to verify
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the AGU NS19 nasal aspirator.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.

level
3 V/m Portable and mobile RF communications equip-
ment should be used no closer to any part of
the AGU NS19 nasal aspirator, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = 1,2√P
d = 1,2√P 80 MHz to 800 MHz
d = 2,3√P 800 MHz to 2,5 GHz
where P is the maximum output power rating of
the transmitter in watts (W) according to the trans-
mitter manufacturer and d is the recommended
separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site surveyª,
should be less than the compliance level in each
frequency range
