* 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 access 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 WarmCloud is used exceeds the applicable RF compliance level above, the WarmCloud system should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the WarmCloud.
** Over the frequency range of 150 kHz to 80 MHz, field strength should be less than 3 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the WarmCloud system, including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1,17 √ P
d = 1,17 √ P
80 MHz to 800 MHz
d = 2,33 √ 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 metres (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey*, should be less than the compliance
level in each frequency range**
Interference may occur in the vicinity of equipment marked with
the following symbol:
