Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the Product requires continued
operation during power mains
interruptions, it is recommended
that the Product be powered from
an uninterruptible power supply
or battery.

Portable and mobile RF
communications equipment should be
used no closer to any part of the
Product, included cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
d = 1,2√P
150 KHz to 80 MHz
d = 1,2√P
80 MHz to 800 MHz
d = 2,3√P
80 MHz to 2,5 GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacture and
d
is the recommended
separation distance in meters (m).
Field strengths from fixed transmitters,
as determined by an electromagnetic
site survey, should be less than the
compliance leave in each frequency
range.
Interference may occur in the vicinity of
equipment marked with the following
symbol.
