The UnicLine S Dental Delivery System is intended for use in the electromagnetic environment
specified below. The customer or the user of the UnicLine S Dental Delivery System should
assure that it is used in such an environment.

3 Vrms
150 kHz to 80 MHz
3 Vrms Portable and mobile RF communications
equipment should be used no closer to any
part of the UnicLine S dental unit,
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 = 1.2√P 800 MHz to 2.5 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
survey,
a) should be less than the
compliance level in each frequency range b)
Interference may occur in the vicinity of
equiptment marked with the following
symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and refection from structures, objects and people.
a) Field strengths from fixed transmitters, such as base stations for radio(cellular/cordless)
telephones and land mobile radios, amateur radio, AM & FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the UnicLine S Dental
Delivery System is used exceeds the applicable RF compliance level above, the UnicLine S
Dental Delivery System should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or
relocating the UnicLine S Dental Delivery System.
b) Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m
