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
EUT is used exceeds the applicable RF compliance level above, the EUT should be observed to
verifynormal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the EUT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V / m.
Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the FireCR Dental system.
The FireCR Dental
system is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The user of the FireCR Dental
system can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the FireCR Dental system as recommended
below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance (d) in meters (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.

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 reflection from structures, objects, and people.
