Manufacturer’s Declaration –Electromagnetic Emissions
The Joerns ECS bed is intended for use in the electromagnetic environment (for professional healthcare) specied
below. The customer or the user of the Joerns ECS bed should assure that it is used in such an environment.
Emissions test Compliance Electromagnetic environment-guidance (for professional

RF emissions
CISPR 11
Group 1
The Joerns ECS bed 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.

Recommended separation distance between portable and
mobile RF communications equipment and the Joerns ECS Bed
The Joerns ECS bed is intended for use in an electromagnetic environment (for professional healthcare) in which
radiated RF disturbances are controlled. The customer or the user of the Joerns ECS bed can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Joerns ECS bed 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
meters (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 a󰀨ected by absorption and
reection from structures, objects, and people.
