8. Important information
Electromagnetic
environment –
guidance
Mains power quality
should by that of a
typical commercial or
)
T
hospital environment.
If the user of the Nio
)
5MP LED Display
T
requires continued
operation during power
mains interruptions, it is
recommended that the
Nio 5MP LED Display
be powered from an
uninterruptible power
supply or a battery.
Power frequency
magnetic fields should
be at levels characteristic
of a typical location in
a typical commercial or
hospital environment.
Portable and mobile
RF communications
equipment should be
used no closer to any
part of the Nio 5MP LED
Display, including cables,
than the recommended
separation distance
calculated from the
equation applicable
to the frequency
of the transmitter.
Recommended
separation distance
d = 1.2√P
d = 1.2√P 80 MHz to 800
MHz
d = 2.3√P 800 MHz to 2.5
Ghz
Where P is the maximum
output power rating
of the transmitter in
watts (W) according
to the transmitter
manufacturer and d
is the recommended
separation distance in
meters (m).
