Mains power quality should be that of a
typical commercial or hospital environment.
If the user of the TAURUS C1 requires
continued operation during power mains
interruptions, it is recommended that the

dental chair unit should be used no closer
to any part of the TAURUS C1, including
cable, than the recommended separation
distance calculated from the equation

according to the transmitter manufacturer
and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
