The WarmCloud WarmCloud system is intended for use in the electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the system can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the WarmCloud
WarmCloud system as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m)
can be established using the equation applicable to the frequency of the transmitter, where P is the maximum output power
rating in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for 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.

Compliance
The WarmCloud WarmCloud system uses RF energy only for its internal
Group 1
function. Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment.
Class B
The WarmCloud WarmCloud is suitable for use in all establishments,
including domestic establishments and those directly connected to the
Class B
public low-voltage power supply network that supplies buildings used
for domestic purposes.
