¹) Field strengths from fixed transmit-
ters, 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 theo-
retically with accuracy. To assess the
electromagnetic environment due to
fixed RF transmitters, an electromag-
netic site survey should be considered.
If the measured field strength in the lo-
cation in which the VOLCANO MEDIC
Vaporization System is used exceeds
Recommended Separation Distances between portable and mobile
RF Communications Equipment and the VOLCANO MEDIC Hot Air Generator
The VOLCANO MEDIC Hot Air Generator is intended for use in an electromag-
netic environment in which radiated RF disturbances are controlled. The customer
or the user of the VOLCANO MEDIC Hot Air Generator can help prevent electro-
magnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the VOLCANO MEDIC
Hot Air Generator 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 determined
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.
Note 1
At 80 MHz and 800 MHz, the higher
frequency range applies.
Note 2
These guidelines may not apply in all
situations. Electromagnetic propaga-
tion is affected by absorption and re-
flection from structures, objects and
people.
Medical electrical equipment is sub-
ject to special precautions with re-
spect to electromagnetic compatibil-
ity. The relevant verification according
to EN 60601-1-2 is available.
