The Mesh Nebulizer with Rechargeable Battery is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Mesh Nebulizer with Rechargeable Battery can
help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and
the Mesh Nebulizer with Rechargeable Battery 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 metres (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
manufacture

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.
Interference may occur in the
vicinity of equipment marked
with the following symbol:
NOTE1:At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2:These guidelines may not apply in all situations. Electromagnetic is
affected by absorption and reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cord-
less) 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 Mesh Nebulizer with Rechargeable Battery is used exceeds the applicable RF
compliance level above, The Mesh Nebulizer with Rechargeable Battery should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Mesh Nebulizer with
Rechargeable Battery.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3V/m.
