Technical Specifications
Recommended separation distances between portable and
mobile RF communications equipment and the CairMax Duo control unit
The CairMax Duo control unit is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the CairMax Duo control unit can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the control unit 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 estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter 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.
Guidance and manufacturer’s declaration – electromagnetic emissions
The CairMax Duo is intended for use in the electromagnetic environment specified below.
The customer or the user of the CairMax Duo should assure that it is used in such an environment.

RF emissions CISPR 11
Group 1
The control unit uses RF energy only for its internal
function. Therefore, its RF emissions are very low
and are not likely to cause any interference in nearby
electronic equipment.
RF emissions CISPR 11
Class B
The control unit is suitable for use in all establishments,
including domestic establishments and those directly
connected to the public low-voltage power supply
network that supplies buildings used for domestic
purposes.
