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

P
is the maximum output power rat-

to the transmitter manufacturer and
d
is the
recommended separation distance in meters
(m). Field strengths from fixed RF transmit-
ters, as determined by an electromagnetic
site survey, should be less than the compli-
ance level in each frequency range.
