For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres
(m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflec-
tion from structures, objects and people.

Problem
ICS AirCal Overheating Warning sounds an aud-
ible continuous beep.

1. Water Reservoir is low/empty.
2. ICS AirCal has been tilted 20° or more
while the pump was operating, there is a
risk of that the pump took in air instead of
water.
3. ICS AirCal is not functioning properly.

Option 1 :
Look at the Water Level Display. If the bar is orange, this means you
need to refill the water in the ICS AirCal. Turn off the ICS AirCal. Fol-
low the Filling and Priming procedure in
cedure ► 9
. Turn on unit and verify that it is working properly.

Option 2
Look at the Water Level Display. If the bar is blue, then you should
have sufficient water but it should be verified. Turn off the ICS AirCal.
Follow the Filling and Priming procedure in
cedure ► 9
.
However, visually see if there is water present in the reservoir. If
there is no or very low water refill the water. Turn on unit and verify
that it is working properly.
Whether the units works or not, contact Natus Medical technical
support and report that the ICS AirCal is not performing as
expected.
