Guidance and Manufacturer’s Declaration - Electromagnetic Immunity (Continued)
The 3600 Handpieces are intended for use in the electromagnetic environment specified
below. The customer or the user of the 3600 Handpieces should assure that it is used in
such an environment.

Where P is the maximum output 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 near the equipment 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 reflection from structures, objects, and/or people.
a.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and 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 3600 Handpieces is
used exceeds the applicable RF compliance level above, 3600 Handpieces should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the 3600 Handpieces.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
