- ELECTROMAGNETIC IMMUNITY
The Compex Performance is designed for use in the electromagnetic
environment stipulated below. The buyer or user of the Compex
Performance must ensure it is used in this recommended environment.
Portable and mobile RF communication devices must only be used relative to the Compex
Performance and its wiring at a distance which is not less than the spacing recommended and
calculated using the appropriate equation for the transmitter's frequency. Recommended
Where P is the maximum output power of the transmitter in watts (W) set by the manufacturer's
specifications and where d is the recommended spacing in metres (m). The field intensity of RF fixed

Interference may occur close to any appliance identified by the following symbol:
Electromagnetic wave propagation is modified by absorption and reflection due to buildings,
In the event of abnormal operation, new measures may then be imposed, such as realignment
