Version 02.02 • 04AUG2022
The use of accessories not recommended by ERT may result in an increased electromagentic
radiation or a reduced interference immunity of the SpiroSphere.
Guidance and Manufacturer µ s Declaration ± Electromagnetic Emissions
The SpiroSphere 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.
EMC Basic Standard Compliance Electromagnetic Environment ± Guidance
RF emissions CISPR 11 Group 1 The SpiroSphere uses RF energy for internal
function. Therefore, its RF emissions are very low
and are not likely to cause any interference to
nearby electronic equipment.
RF emissions CISPR 11 Class B The SpiroSphere unit is suitable for use in all
establishments, including domestic establishments
and those directly connected to the public low-
voltage power supply network that supplies
buildings used for domestic purposes.
