If the user of the Optomed Aurora requires
continued operation during power mains
interruptions, it is recommended that the
device be powered from an uninterruptible
power supply or a battery.

Portable and mobile RF communications
equipment should be used no closer to
any part of Optomed Aurora, 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 2.7 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).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site

, should be less than the compliance
level in each frequemcy range

Interference may occur in the
vicinity of equipment marked
