Mains power quality should be that of a
typical commercial or hospital
environment. If a dip or an interruption of
mains power occurs, the current of the
CT40 may be dropped off from normal
level, it may be necessary to use
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.
NOTE: UT is the a.c. mains voltage prior to application of the test level
In the event of an error, the device will auto-recover within 5 seconds.

Portable and mobile RF communications equipment should
be used no closer to any part of the CT40, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
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 metres (m).
