Note: The EMISSIONS characteristics of this equipment make it suitable for use in industrial areas and hospitals (CISPR 11 Class A). If it used in a
residential environment (for which CISPR 11 Class B is normally required) this equipment might not offer adequate protection to radio-frequency
communication services. The user might need to take mitigation measures, such as relocating or re-orientating the equipment.

ELECTROMAGNETIC ENVIRONMENT – GUIDANCE
The SH870 Humidifier uses RF energy only for its internal function.
Therefore, its RF emissions are very low and not likely to cause any
Interference in nearby electronic equipment.
The SH870 Humidifier is suitable for use in all establishments, including
domestic and those directly connected to the public low-voltage power
supply network that supplies buildings used for domestic purposes.

ELECTROMAGNETIC ENVIRONMENT – GUIDANCE
Floors should be made of wood, concrete or ceramic tile.
If floors are covered with synthetic material, the Relative
Humidity should be at least 30%.
Mains-power quality should be that of a typical commercial
or hospital environment.
Mains-power quality should be that of a typical commercial
or hospital environment.
Mains-power quality should be that of a typical commercial
or hospital environment. If the user of the SH870 Surgical
Humidifier requires continued operation during power mains
usage, it is recommended that the SH870 Surgical Humidifier
be powered from an uninterruptible power supply or battery.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commercial or
hospital environment.
