Guidance and manufacturer's declaration - Electromagnetic immunity
The mesh nebuliser is intended for use in the electromagnetic environment specified below . The
customer or the user of mesh nebuliser should assure that it is used in such an environment.

GB/T 17626.6
Radiated RF
GB/T 17626.3
Note 1: At 80MHz and 800MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic is affected by absorption and
reflection from structures, objects and people.
a. Stationary transmitters, such as base stations for wireless (peak/cordless) telephones and terrestrial
mobile radios, amateur radio, AM and FM radio broadcasting, and television broadcasting, etc., whose
field strength cannot be accurately predicted in theory. In order to assess the electromagnetic environ-
ment of fixed radio frequency transmitters, electromagnetic field surveys should be considered. If the
measured field strength of the microgrid device is higher than the above radio frequency compliance
level, the microgrid device should be observed to verify its normal operation. If abnormal performance
is observed, supplementary measures may be necessary, such as re-adjusting the direction or position
of the micro-mesh device.
b. During the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

The Mesh Nebuliser is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled.The customer or the user of the Mesh Nebuliser can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment(transmitters)and the Mesh Nebuliser as recommended below,according to the maximum

Portable and mobile RF communications equipment
should be used no closer to any part of the device,
including cables, than the recommended separation

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
