The CONCHATHERM NEPTUNE Humidifier is intended for use in the electromagnetic environment specified below. The
customer or the user of the CONCHATHERM NEPTUNE Humidifier 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 CONCHATHERM
NEPTUNE Humidifier, including cables,
than the recommended separation dis-
tance calculated from the equation appli-
cable to the frequency of the transmitter.

Field strengths from fixed RF transmitters,
as, determined by an electromagnetic site
survey,
a
should be less than the compli-
ance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following
symbol.
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 electro-
magnetic site survey should be considered. If the measured field strength in the location in which the CONCHATHERM NEPTUNE Humidifier is used exceeds the
applicable RF compliance level above, the CONCHATHERM NEPTUNE Humidifier should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the CONCHATHERM NEPTUNE Humidifier.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
