to the transmitter
manufacturer and d

in meters [m].
Field strengths from
fixed RF transmitters,
as determined by an

, should be
less than the com-
pliance level in each
frequency range
2) .
Interference may occur
in the vicinity of
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 people.

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 electro-
magnetic site survey should be con-
sidered. If the measured field strength
in the location in which the
MIGHTY
MEDIC Vaporizer is used exceeds
the applicable RF compliance level
above, the MIGHTY MEDIC Vaporizer
should be observed to verify normal
operation. If abnormal performance is
observed, additional measures may
be necessary, such as re-orienting
or relocating the MIGHTY MEDIC Va-
porizer.
2) Over the frequency range 150 kHz
to 80 MHz, field strengths should be
less than 3 V/m.
Recommended Separation Distances between portable and mobile RF
Communications Equipment and the MIGHTY MEDIC Vaporizer
The
MIGHTY MEDIC Vaporizer is intended for use in an electromagnetic en-
vironment in which radiated RF disturbances are controlled. The customer or
the user of the
MIGHTY MEDIC Vaporizer can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mo-
bile RF communications equipment (transmitters) and the
MIGHTY MEDIC
Vaporizer as recommended below, according to the maximum output power
of the communications equipment.
