Portable and mobile RF
communications equipment must not
be used at a distance, including the
cables, from the Hill-Rom® 900 that is
less than the recommended
separation distance. This distance is
calculated using the formulae
applicable according to the frequency
of the transmitter.

where P is the maximum output power
of the transmitter in Watts (W)
assigned by the manufacturer of the
transmitter and d is the recommended
separation distance in meters (m).
The field levels emitted by fixed RF
transmitters, as determined by an
electromagnetic measurement of the
site

, must be below the level of
compliance in each frequency band
b
.
Interference may occur close to
devices identified with the following
symbol:
Note 1: At 80 MHz and 800 MHz, the separating distance in the upper frequency band applies.
Note 2: These recommendations may not apply to certain situations. The propagation of electromagnetic
waves is affected by absorption and reflection due to structures, objects and persons.
a. The field levels of fixed transmitters, such as radio telephone bases (cell/wireless) and
terrestrial mobile radios, amateur radios and AM, FM and TV communication radios cannot be
theoretically evaluated precisely. Site measurements are required in order to obtain the
electromagnetic environment due to fixed RF transmitters. If the field level measured in the
working environment of the Hill-Rom® 900 is greater than the above applicable levels of
compliance, the operation of the Hill-Rom® 900 must be checked. If any anomalies are
detected, additional measures must be taken, such as redirecting or relocating the reference
equipment.
b. The field level must be less than 3 V/m above the frequency band 150 kHz to 80 MHz.
Manufacturer's guide and declaration – electromagnetic immunity
