Mains power quality should be that of a
typical commercial or hospital environment.
If the user of IndiGo requires continued
operation during mains power interruptions,
it is recommended that IndiGo be powered
from an uninterruptible power supply or
battery.
Power frequency magnetic elds should
be at levels characteristic of a typical
location in a typical commercial or hospital
environment.
Electromagnetic environment -guidance
Portable and mobile RF communications equipment should
be used no closer to any part of IndiGo, including cables,
than the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter. Recommended separation distance
Where is the maximum output power rating of the
P
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation in
meters (m). Field strengths from xed RF transmitters, as
determined by an electromagnetic site survey,
less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked
with the following symbol:
